Cucurbit Hand Pollination with Brush

In optimal conditions insects, mainly bees, pollinate our veggies. Wind works for some plants. Other times due to weather or stresses, humans help!

Wind-pollinated veggies

such as tomatoes, peppers and eggplant, are fertilized by the beating of Bumblebees’ and other insects’ wings, at exactly the right frequency! More pollen is released and pollination is more efficient. It’s called BUZZ POLLINATION! About 11 AM, when the male flower anthers (they hold the pollen) are most open, you can improve your tomato, eggplant and pepper production by giving the cages they are in or the main stems of your plants a few sharp raps, or gently shake the stems, to help the flowers self pollinate. Or hand pollinate using a small paintbrush or cotton swab. In the greenhouse you can help these veggies simply by adding a fan to move the pollen.

Honey bees don’t pollinate tomatoes, peppers, potatoes, eggplant or blueberries, or other Solanaceae, so build solitary bee condos for native bees. Native bees, per Cornell entomology professor Bryan Danforth, are two to three times better pollinators than honeybees, are more plentiful than previously thought and not as prone to the headline-catching colony collapse disorder that has decimated honeybee populations. A Jan 2019 UK study says pollination by wild bees yields larger strawberries than pollination by honey bees! This led them to say it’s worth it to make habitat for them!

The very best Solanaceae pollinator is a Bumblebee!!! See more! Bumblebees fly earlier in spring and bring in our first spring crops! And they don’t sting!

And, did you know Flowers can hear buzzing bees—and it makes their nectar sweeter!

While you are helping your tomatoes pollinate, if you are growing them in cages, also very gently help them up through the cages. Remove any bottom leaves that might touch the ground when weighted with water. Remove any diseased leaves ASAP!

Pollination Cucurbits Male Female Flowers     Pollination by Hand Cucurbits Male Stamen to Female Stigma

Squashes, melons and monoecious cucumbers

can easily be hand pollinated. Cukes are notorious for needing help being fertilized! Cucurbits have male and female blooms on the same plant. If there are not enough pollinators about, we need to help. Also, multiple visits from the bees are required for good fruit set and properly shaped cucumbers. Male flowers open in the morning and pollen is only viable during that day. Hand pollinate during the morning hours, using only freshly opened flowers. You can use a small pointy paint brush, a cotton swab, Q-tip, your finger, and move pollen from the male stamen to the center of the female flower. Or the best, most complete method is to take the male flower off the plant, pull the petals off, and gently roll the male flower anther around and over the female stigma in the center of the female flower. The pollen is sticky, so it may take some time. One male anther can pollinate several females. Repeat. Female blooms will simply drop off the plant if they are not pollinated. So when your cukes are in production, you need to do this daily.

Don’t be confused by the little fruit forming under the female flowers and think pollination has already happened. The flower needs to be fertilized, and adequately, or the flower and fruit just fall off. Flowers not pollinated enough, that don’t abort, make misshapen fruits. That goes for corn having irregular to lacking kernels. Misshapen Strawberries are called cat-faced. Squash and cucumbers can be deformed. On an unwindy day, tilt the stalk so the corn tassels are over the silks and tap the stalk. You will see a shower of pollen fall on the silks. You may need to do it from one plant to another so you don’t break the stalk trying to get the pollen to fall on silks on the same plant.

Planting a lot of plants close together stresses plants. At higher densities, plants compete for water, nutrients, and sunlight, and the resulting stress can lead to a higher proportion of male flowers, less female flowers, the ones that produce. If you really want more fruit, give them room to be fruitful. The same goes for other stresses – damage from insects or blowing soil, low light intensities, or water stress – less female flowers are produced.

Weather affects pollination. Sometimes cool overcast days or rain, when bees don’t fly, there is no pollination. Rain washes pollen away. High humidity makes pollen sticky and it won’t fall. Drought is a problem for corn pollination. Too high nighttime temps, day temps 86°F and above, will keep your tomatoes, cucumbers and other vegetables from making pollen or setting fruit unless they are high temp tolerant varieties. Too windy and the pollen is blown away.

If it is your cucumbers that are not pollinating well each year, try parthenocarpic varieties. Parthenocarpic varieties produce only female flowers and do not need pollination to produce fruit. This type of cucumber is also seedless. Try a few varieties and see if you like them.

Pollinator Habitat is crucial! Most important of all is to plant flowers for every season possible in your area, near or right beside your plants, make those bee homes for wild bees! From Cornell: Native bees are two to three times more effective than honeybees! However, if weather isn’t with you or other stressful conditions occur, hand pollinating is the answer.

May your Veggie Basket be overflowing!

The Green Bean Connection newsletter started as correspondence for the Santa Barbara CA USA, Pilgrim Terrace Community Garden. All three of Santa Barbara city community gardens are very coastal. During late spring/summer we are in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is.

June Garden Wedding Lyons Farmette CO

What’s a garden for? Fertility and good living! Bridgette and Hoyt got married on a supermoon evening at Lyons Farmette & River Bend, Lyons CO! 

June is Midsummer Magic month! Divine small Faery beings will be celebrating your garden! June 21, 24, 25 or a date close to the Summer Solstice, any day June 19–24, is celebrated as Midsummer Night; June 24 is Faery Day! In Santa Barbara Summer Solstice festival and parade weekend is June 21-23rd!

Abundance is flowing, harvests are happening!

Tomato Indigo Rose Purple Anthocyanins

Tomatoes are coloring up nicely, their sidekick basil is potent delish, golden zucchini and lettuces of all kinds are being eaten, purple pole beans are being harvested by adults and children! I’ve seen some big fat full size cukes and humongous Seascape strawberries! Be careful with some of your harvests. Clip rather than break away and damage or pull your plant up.

Cherry tomatoes come in first. Fertilize your toms with a slow release fertilizer once the fruiting begins.
This year three of us at Rancheria Garden are trying Blue Berries Tomatoes! Baker Creek says: Here’s a small cherry variety from Brad Gates, Wild Boar Farms. Very dark purple color, which means it’s super-rich in anthocyanins. Unripe, the fruit is a glowing amethyst purple. At maturity it turns deep red where the fruit was shaded; the areas that received intense sunshine are a purple so deep it’s almost black! The flavor is intensely fruity and sugar-sweet! Plants are very productive, yielding all season in elongated clusters that look so beautiful.Reviewer Rebecca of Old Mosses Secret Garden said: I bought this selection for my whimsical choice. My experiences were similar to others opinion, they are abundant, vigorous and salad enhancing, plus they make a wonderful antioxidant jam spread. What I wanted to share about the blue berry tomatoes is that they are top of the menu choices for BATS. Bats were not on our urban radar, four years later five thousand bats have moved in and troll the garden where the fence lines are abundant with these little tasty gems, which get devoured . This plant is the greatest organic gardening boon ever sprouted. For fair reveal though I have hundreds of evergreen spruce that also get bat vacuumed for more meaty choices, so Thank you Baker seed, your diligence to excel is my secret weapon for a fantastic garden.

Harvest at your veggie’s peak delicious moment! Juicy, crunchy, that certain squish in your mouth, sweet, full bodied flavor, radiant, vitamin and mineral rich! Besides being delicious and beautiful, it keeps your plant in production. Left on the plant, fruits start to dry and your plant stops production, goes into seeding mode. The fruit toughens or withers, maybe rots, sometimes brings cleanup insect pests that spread to other plants. Keep beans picked, no storing cucumbers on the vine. Give away or store what you can’t eat. Freezing is the simplest storage method. Cut veggies to the sizes you will use, put the quantity you will use in baggies, seal and freeze. Whole tomatoes, chopped peppers and beans, diced onions. Probiotic pickle your cukes. Enjoy your sumptuous meals! Sing a song of gratitude and glory!

Plant more! Try some new ones too!

In those empty spots you have been saving, plant more rounds of your favorites! Check your lettuce supply. Put in more bolt resistant, heat and drought tolerant varieties now. Some heat tolerant lettuce varieties are Sierra, Nevada, Jericho, Black Seeded Simpson. That ruffly little beauty queen Green Star has excellent tolerance to hot weather, bolting, and tipburn. Rattlesnake beans keep right on producing when temps get up to 100 degrees! Plant more of everything except winter squash, big melons, pumpkins, unless you live in the hot foothills.

Put in plants that like it hotter! Long beans grow quickly from seed now. They grow later in the season when your other beans are finished. They make those enormously long beans in the ample late summer heat. Keep watch on them, in spite of their size they grow quickly, harvest promptly, usually daily! Certain varieties of them don’t get mildew either! Their unique flavor keeps your table interesting. Plant Okra now, it grows quickly in this warmer weather! More eggplant and also tomatoes you have been waiting to put in the now drier fungi free ground. Plant mini melons like Sugar Baby watermelons!

For those of you that are plagued with fungi diseases in your soil, the drier soil now makes this a better time to plant. Select wilt and blight resistant Tomatoes. Remember, when you plant your tomatoes and cukes, build a mound and make a basin whose bottom is higher than the surrounding soil. You want drainage and a wee bit of drying to reduce the potential of fungi – verticillium and fusarium wilts, blights. More Special Planting and growing tips for your Tomatoes and Cucumbers!

Plant WHITE potatoes with Zucchini to repel squash bugs, radishes with cukes and Zucchini to repel cuke beetles, and radishes with eggplant, potatoes and arugula to repel flea beetles.

If you have more space or you lost a plant here or there, think on putting in some perfect companion plants! One of the Three Cs are super!

  1. Calendula – so many medicinal uses, bright flowers, and traps aphids, whiteflies, and thrips! Yep. Plant Calendula by tomatoes and asparagus.
  2. Chamomile –  is called the Plant Dr! It heals neighboring plants and improves the flavor of any neighboring herb! The flowers make a lovely scent and the tea is sweet.
  3. Comfrey – aka Knitbone, is an amazing medicinal herb, a super nutritious compost speeder upper! Plant it by your compost area.

Tasty herbs – chives, parsley, or more permanent perennials like rosemary, oregano (invasive), thyme are flavorful choices.

When you put them in the ground, pat Mycorrhiza fungi right on the roots of all your transplants except Brassicas. It increases uptake of nutrients, water, and phosphorus that helps roots and flowers grow and develop. Ask for it bulk at Island Seed & Feed in Goleta.

Here’s your tending list for Beauty and Bounty!

Summer Solstice Sunflower

Water regularly so everyone is moist the way they like it! Seeds and seedlings daily. Peppers like moist, so as they need it. Others not so water critical on average need an inch a week; water beans, cukes, lettuces and short rooted varieties of strawberries more frequently – lettuces could be daily on hot windy days. To double check use the old finger test or push your shovel in and wedge the soil open enough so you can see if it is moist as deep as it needs to be. Watering at ground level, rather than overhead watering, keeps your plant dry. That means less mildew, less fungal diseases, especially for fuzzy leaved plants like toms and eggplant.

If at all possible, water in the AM before 10:30 to let leaves dry before evening to prevent mildew – beans and cucumbers are especially susceptible. Plant fewer beans further apart for air flow. If your plants are near a street or there has been a dusty wind storm, wash the dust off your plants so they can breathe, and to make them less attractive to Whiteflies.

In spite of below average May temps in Santa Barbara area, the ground has heated up. Finally. if you haven’t yet, it’s time to mulch! MULCH and replenish tired mulch. No more than an inch of straw mulch with toms and cukes. They need airflow so the soil can dry a bit and reduce harmful fungi. Otherwise, put on 4 to 6 inches minimum to keep light germinating seeds from sprouting. Mulch any Brassicas you are over summering – broccoli, kale – 4 to 6 inches deep for them too. They need cool soil. Melons need heat! They are the exception – no mulch for them if you are coastal. Yes, they will need more water, so be sure their basin is in good condition and big enough so they get water out to their feeder roots. Put a stake in the center of the basin so you know where to water when the leaves get big. The only place for straw for them is right under the melons.

Keep a sharp eye on tomatoes. Remove leaves touching the ground or will touch the ground if weighted with water! Trim so neighboring plants don’t touch and spread diseases like the wilts or blights. Remember, the wilts are spread by wind as well as water, so neighboring plants are very likely to give it to one another. Try planting other plants between. You can still do rows, just mix up the plants! Your healthier tomatoes will produce more and longer.

POLLINATION is vital & easy to do!

Pollination Cucurbits Male Female Flowers Pollination by Hand Cucurbits Male Stamen to Female Stigma

Improve your tomato, eggplant and pepper production by giving the cages or the main stems a few sharp raps, or gently shake the stems, to help the flowers self pollinate.

While you are helping your tomatoes pollinate, if you are growing them in cages, also very gently help them up through the cages. Remove any bottom leaves that might touch the ground when weighted with water. Remove any diseased leaves ASAP!

Squashes, melons and monoecious cucumbers can easily be hand pollinated. Cukes are notorious for needing help being fertilized! Cucurbits have male and female blooms on the same plant.

Don’t be confused by the little fruit forming under the female flowers and think pollination has already happened. The flower needs to be fertilized, and adequately, or the fruit just falls off. Flowers not pollinated enough, that don’t abort, make misshapen fruits. That goes for corn having irregular to lacking kernels. Strawberries are called cat-faced. Squash and cucumbers can be deformed.

Did you know? Flowers can hear buzzing bees—and it makes their nectar sweeter!

SIDEDRESSING! This IS the time! Feeding when your plants start to bloom and produce is a pretty standard recommendation. But if your baby is looking peaked, has pale or yellowing leaves, an emergency measure could be blood meal. Foliar feeding a diluted fish emulsion/kelp is easy for your plant to uptake. Foliar feeding a tea mix per what each plant might need, is the ultimate feed and it’s not hard to make tea mixes! Your lettuces love it if you scratch in some chicken manure, but no manure in a tea on leaves you will be eating! Pull your mulch back, top with a 1/2″ of compost and some tasty worm castings! If you prefer organic granulated fertilizer, easy to apply, sprinkle it around evenly. But remember, that has to be repeatedly applied. Recover with your mulch, straw, then water well and gently so things stay in place. That’s like making compost and worm tea in place!

Face up to pests! It’s easier to deal with them when there are only a few rather than losing your whole plant or a row of plants. I have already seen Cucumber beetles foraging Zucchini flowers. They are deadly to cucumbers because they transmit bacterial wilt and squash mosaic virus and cucumbers are the most susceptible to the wilts than any other garden veggie. Squish those beetlesSee more Here are tips for Beetle prevention for organic gardeners:

  • If possible plant unattractive-to-cucumber beetle varieties. In 2012 U of Rhode Island trials, best pickling choices are Salt and Pepper and H-19 Little LeafMarketmore 76 was tops for slicing cukes. If you find more current research on best varieties, please let me know!
  • Plant from transplants! The youngest plants are the most susceptible.
  • Interplant! No row planting so beetles go from one plant to another.
  • Delay planting! In our case, most of us already having planted cucumbers, can plant another round late June or when you no longer see the beetles. Start from seeds at home now since transplants may no longer be available in nurseries later on.
  • Plant repellent companion plants BEFORE you plant your cukes. Radish with eggplant, cukes & zukes act as trap plants for flea beetles and to repel cucumber beetles. Radish are the fastest growers, so get them in ASAP if you didn’t before.
  • Natural predators are Wolf Spiders, daddy long legs and Ground Beetles! Let them live! They eat beetle eggs and larvae. And there is a tachinid fly and a braconid parasitoid wasp that parasitize striped cucumber beetle, and both sometimes have large impacts on striped cucumber beetles. When you see a dark hairy fly, don’t swat it! It is doing important garden business!
  • Here is a super important reason to use straw mulch! Per UC IPM ‘Straw mulch can help reduce cucumber beetle problems in at least 3 different ways. First, mulch might directly slow beetle movement from one plant to another. Second, the mulch provides refuge for wolf spiders and other predators from hot and dry conditions, helping predator conservation. Third, the straw mulch is food for springtails and other insects that eat decaying plant material; these decomposers are important non-pest prey for spiders, helping to further build spider numbers. It is important that straw mulch does not contain weed seeds and to make certain that it does not contain herbicide residues which can take years to fully break down.’
  • Organic mulches foster diverse populations of beneficial soil microorganisms that trigger the plant’s internal defenses.
  • At the end of the season or when your plants are done, remove garden trash, tired mulch and other debris shortly after harvest to reduce overwintering sites.

If you are by a road or in a dusty windswept area, rinse off the leaves to make your plants less attractive to whiteflies. Also, asap remove yellowing leaves that attract whiteflies. Pests adore tasty healthy plants just like we do. They also make us see which plants are weak or on their way out. Give those plants more care or remove them. Replace them with a different kind of plant that will do well now and produce in time before the season is over. Don’t put the same kind of plant there unless you have changed the conditions – enhanced your soil, installed a favorable companion plant, protected from wind, terraced a slope so it holds moisture, opened the area to more sun. Be sure you are planting the right plant at the right time! Remove mulch from under plants that were diseased and replace with clean mulch. Do not compost that mulch or put it in green waste. Trash it.

Please always be building compost and adding it, especially near short rooted plants and plants that like being moist. Compost increases your soil’s water holding capacity.

MY Cucumbers! Cucumbers and Cassie, Indiana Veggie Gardener!

MY cucumbers! Cassie lives in Indiana and usually has dirt under her fingernails.

Some people LOVE Cucumbers! Dice ’em or slice ’em, put slices on your eyes, make a soothing skin cream, hair tonic! Sulphur in cucumbers helps stimulate the growth of hair and makes it thick and healthy. Although less nutritious than most fruit, cukes are delicious and good for your health in many ways. 

  • Magnesium, potassium, and the mineral silicon in Cucumbers keep your skin beautiful! The juice cleans your pores by removing dirt, bacteria and excess oil. Cucumbers have a natural cooling effect and reduce the redness, inflammation of blemishes. Their Vitamin E fights free radicals and heals scars. They treat bad breath, so you will look and smell good!
  • Cucumbers will help heal stomach ulcers. Drinking two glasses of cucumber juice every day can cure heartburn. Cukes help reduce your blood pressure. And they lower blood sugars, helping with diabetes.
  • Cucumber contains polyphenols called lignans, and phytonutrients called cucurbitacins. They help prevent the growth of breast, uterus, and prostate cancers.
  • They help get rid of excess uric acid in the body and help maintain healthy kidneys and bladder conditions, even prevent the formation of kidney stones. They also help digestion and reduce constipation!
  • Vitamin B and electrolytes in the cucumber will be useful to help relieve headaches.
  • Weight loss! Cucumbers are 95% water and low calorie! They will help keep you hydrated and delay hunger, as well as improve your joint health and reduce bad cholesterol!

Cucumbers belong to the Cucurbitaceae family, which includes squashes (including pumpkins), luffas, melons, and watermelons. Cucumbers grew wild in India over 4000 years ago and have since traveled worldwide! They have been traded by empires, eaten every day by emperors, brought to Haiti by Columbus in 1494, banned as deadly at times! In 2010 worldwide cucumber production was 57.5 million tons, with majority of the world’s production and export being located in China (40.7 million tons)! As of a 2013 article, In the United States, consumption of pickles has been slowing, while consumption of fresh cucumbers is rising!

Huge Selection of Extraordinary Varieties!

Cucumber Melothria Scabra Mouse Melon TreatsSizes from itsy tiny watermelon-like heirloom Mexican Sour Gherkin AKA Mouse Melons, sandia de raton, to small bumpy pickling types, substantial juicy slicers, to longs like wonderful Chinese Suyos!

Cucumbers can be green, white, golden orange, healthy bitter red orange spiky Gaks, up to 3 meter long brown Kigelias, brilliant red Dragon’s Eggs! You just haven’t lived until you’ve tried a few exotics!

The different shapes are a treat! Mouse Melons, round lemon cucumbers, the standard long shapes, fat Hmongs, African Horned Cucumbers!

You can get big viners, or bush type patio container types with smaller leaves at shorter intervals. Compact yet lots of production!

Now we have varieties producing all female flowers (gynoecious types) that produce seedless fruit earlier have more concentrated production, a longer shelf life. No bees are needed. In experimental trials the following varieties have produced high yields and have resistance or tolerance to common diseases: Burpee Hybrid, Comet A II, Dasher II, Marketmore 80, Slice Master, Sprint 440 II, and Victory!

Disease Resistant Varieties

Read the notes about these varieties! These are features you want to see when picking varieties!

Long Green Slicing

Burpless (hybrid – 62 days to harvest; the original sweet, long, Chinese-type hybrid; does well on a trellis
Marketmore 76 – 68 days; very uniform, dark green, straight fruit; multiple disease resistance
Straight 8 – 58 days; AAS winner; long-time favorite; excellent flavor; evenly dark green fruit

Long Green Slicing (compact plant)

Bush Crop – 55 days to harvest; delicious; 6-8 inch fruit on dwarf, bushy plants
Fanfare – hybrid – 63 days; AAS winner; great taste; high yield; extended harvest; disease resistant
Salad Bush – hybrid – 57 days; AAS winner; uniform 8 inch fruit on compact plants; tolerant to a wide variety of diseases
Marketmore 97 – 55 days. One of the best early northern cucumbers producing long dark green fruit, non bitter. This excellent slicing cucumber variety is tolerant of powdery mildew, cucumber mosaic virus and resistant to scab, providing a good crop under adverse conditions. Very dark green, looks thick skinned, bumpy.

Best of all is to plant powdery mildew resistant varieties like AAS winner gynoecious and parthenocarpic Diva!

Early Varieties

Marketmore 80
BETH ALPHA – 58 days Heirloom. The original Middle-East type. Often a parent for the wonderful high-end Slicing hybrid cucumbers. Probably the best all round cuke. Early, productive over long season, mild. Thin skin, wonderful taste with no ‘bitter ends’.
Dasher II  Early, dark green; concentrated set
Very early:   Lightning, Speedway, Thunder

Heat/Cold, Drought Tolerant Varieties

If your area has short cool summers, go for early, cold tolerant, smaller fruited varieties, container types. In hot areas, enjoy those big slicers and Japanese longs! Sometimes heat and drought go together, or you would just like to save water. Here’s a great page at SFGate that lists six heat tolerant varieties with all their details! Little Leaf H-19 (parthenocarpic) and Suyo Longs are terrific! Ashley withstands heat and has good downy mildew resistance.

Monoecious or Gynoecious

Affects  your choice of plant for harvest! Monoecious is over the season a steady table supply harvest. Gynoecious is like bush plants, all at once harvest for canning. Female flowers of gynoecious varieties still need to be fertilized with pollen from male flowers, so a certain percentage of monoecious plants need to be planted along with the gynoecious plants to serve as pollenizers. Most seed companies provide cucumber seed blends that contain 85% to 90% gynoecious seed and 10% to 15% monoecious seed.

NOTE: If you are planting non gynoecious types, all female flowers, not to worry if first flowers don’t make baby cukes! Male blossoms come first so they can fertilize the female blooms unless you have an all female no pollination needed gynoecious and parthenocarpic variety. Cucumber vines will produce the greatest amount of female flowers when day length shortens to approximately 11 hours per day. Plant a round at the time you can hit that window!

Choosing Companion Plants

Your climate, soil and many, many other factors determine how well plants grow together. I’ve seen gardeners make exact opposite claims with the pictures to prove it. Bottom line is try things for yourself!

Companion plants enhance each other’s growth, repel pests! Adding companion plants adds a whole new dimension to planning your garden! Spacing changes. Locations change. Your plants are healthier, there is more production, your growing season is extended. By intermingling companion plants, biodiversity happens naturally. For example, rather than having a separate herb area, spread them throughout your garden. Put those herbs to work beside veggie plants they help and favor! Plant 4 or 5 plants with an herb at the hub of the wheel! The herb will serve all those plants at once!

Cucumbers & Dill! This is a companion combo based on timing and usage! Plant Dill at the same time as your cukes, and with your cucumbers so they will mature at the same time for pickling, probiotics, and you have convenience of harvest! Another natural combination is basil and tomatoes!

A super spatial combo is trellising Cucumbers below, letting pole beans grow up, through and above the cukes!

Cucumber Beetles are BAD. They vector bacterial wilts, squash mosaic virus, and others. They harm beans and Cucurbits, the Cucumber family – that’s cucumbers, squash, pumpkin, ZUCCHINI, some gourds.

RADISHES get the gold star award! They repel a variety of beetles, including the nasty disease carrying Cucumber Beetle! Plant Radishes, followed by Cucumbers so the radishes will be up and running when your cucumbers need them! Let the radishes grow out. It’s not like you are planting a crop of radishes there. You want them to mingle among your cukes. You won’t need very many radishes to do this. If you didn’t get them in before planting time, get them up and growing ASAP!

Other helpers! Basil or summer savory, and dwarf marigolds, can mask cucumbers from cucumber pests like striped or spotted cucumbers beetles.

Here are some valuable tips from Jim and Mary at Old World Garden Farms.Plant Sacrificial and Repelling Crops : Many successful growers will plant sacrificial plants that the beetles love nearby their cucumber plants.

  • Alyssum, Zinnias and Pumpkin vines are all excellent sacrificial crops. Beetles prefer them even more than cucumbers, so they tend to stick to attacking them. It makes them easy to spot and destroy, and gives a fighting chance for your cukes.
  • You can also plant repelling crops that beetles dislike such as radishes, oregano (can be invasive – plant in a 5 Gal bucket), and nasturtiums (nasturtiums can bring snails). Plant them right with your cucumbers to help repel the beetles away.

INCOMPATIBLE Plants

Potato, super aromatic herbs like Sage.

Planting for Pleasure!

Long Cucumbers hanging from Overhead Trellis!

First decide how you will grow your Cukes! On the ground, trellising or overhead?!

That determines how you layout your garden! Overhead may require separate additional space, or you might install it over your patio but not so tall that you can’t reach to harvest! Unique! Trellises will make varying kinds of shade depending on what kind of trellis you use. You might like some shade for summer lettuces. A simple vertical trellis still makes shade, but less if you install it along the direction of the summer sun’s path! If you have already planted other plants and don’t want to shade them, you might choose smaller varieties of cucumbers that will grow to less heights, have smaller leaves.

Small pickling cucumbers are easy on a vertical trellis. If you are growing heavy slicers, a vertical trellis is still good. If you are growing a LOT of long cukes, you might grow them on an overhead, let them hang for easy harvesting. Cucumbers up on trellises will ripen all the way around while ground growing might leave an unripened yellow area on their down side.

Choose trellis shapes that give you easy picking access and that will give ample space for the variety of cucumber you choose!

Getting your cucumbers off the ground keeps them out of the nibbling insect zone, but it is a little cooler up there and may delay growth a bit. If you are in a cool windy coastal area, you might decide to grow low shrub porous windbreaks to shelter an area, and leave your cukes on the ground. Mulch with only an inch layer of straw to keep them off the ground and the insects happy under the mulch. The thin straw layer allows aeration and some light through to keep the soil warm.

Sun, Soil, Spacing

Full summer sun! Cucumber is not a ‘winter’ plant, they grow best at 81 F to 101! They will do alright at 60 degrees at night, and above 70 degrees during the day. If you are coastal cool, if possible, find a SHELTERED spot for them so they can be good and warm! In the garden plant them on the sunny side of corn, beans or tomatoes. Look for a light colored wall, west facing, with no chilling wind that whips by. A light, sandy loam soil works well for early production. Cucumbers thrive in well drained, fertile soil and need a pH above 6.0.

Some northern gardeners prepare their cukes, melons, squash, peppers and tomato soil well in advance, in fall for spring! They compost in place – pile on manure, chopped leaves and grass, sprinkle on coffee grounds and kitchen scraps, wood ashes from winter fires, etc. In spring dig a foot square hole, fill with your luscious compost, plant your seed right in that compost! Lasts all season if you live in a short season area, and no compost is wasted where no plant is planted! As long as you get that compost out to just beyond the feeder root area your mature plant will have, it’s good.

Incorporate a layer of worm castings at the top of your planting area if you are planting seeds. Castings improve and speed germination, improve water holding capacity to keep your seedlings moist longer!

Spacing depends on which varieties you plant and whether you trellis or not. For trailing cucumbers on the ground, plant 3 to 4 seeds in hills, spacing the hills 3 to 4 feet apart in the row and space rows 5 feet apart. If you plan to trellis your cucumbers, space the hills 2 feet apart in the row and thin to one plant per hill. If you use a vertical trellis, as your plants grow, be prepared to gently weave them up the trellis or tie them in place. Cukes are not like beans or peas that do it by themselves and bend easily.

Hilling or Basins?! If you live in a wet summer rainy area, hilling is great for drainage, though sometimes toward the end of summer, salts accumulate on the top of the soil and water simply runs off. Or the hill flattens from watering, roots are exposed, you need to replenish the soil. Laying on compost mulch covered with a straw mulch will help that. In hot Mediterranean summer dry areas like SoCal, a dripline-wide basin corrals the water right where your plant needs it. Put a stake in the center of the basin so you know where to water. If your soil is infected with wilts or blights, make a hill, put the basin on top, with the bottom of the basin above the regular soil level. This waters your plant, allows drainage and some drying, reducing the fungi. Mulch with only 1″ of straw to allow airflow, but to keep leaves from touching soil. Keeping the leaves from touching the soil is critical because it is the number one way wilts access your plants.

Germination

Cucumbers are frost tender. Wait to plant until the soil has warmed up to 65° degrees or above.

Pre sprouting is smart! Soak your seeds in water for 5 to 10 hours, drain. Put them on damp paper towels wrapped loosely in an unsealed plastic bag and put in a warm spot. 70-85 degrees is optimum. Check the bags every day – keep the towels moist. The seeds will sprout in a few days. It saves time and guarantees you will have a plants in every space! You won’t waste time waiting for failed seeds in the ground. Seed Soaking/Presprouting Tips Plant your sproutlings very gently. 

Transplant Technique Separating Lemon Cucumbers - John Kohler

Selecting Transplants to save money! Not everyone wants to plant from seed! Not everyone wants to spend a ton of bucks on transplants either! Ok, so do it John Kohler style! See this video of him separating out ELEVEN lemon cucumbers from one 4″ container he purchased for $1.79 – those were the days, ha, ha! I didn’t believe it, but he did it easy! And I’ll bet they all grew! You can use this technique with many plants. 

Tag your seedlings and transplants with the date planted, variety name, # of days to maturity. Having your plant date and days to maturity tells you at a glance how well they are doing per how long they have been in the ground. If your seeds don’t germinate, you know your seed is compromised or too old. If there are no fruits when expected, are you over fertilizing and your plant is going to leaf and no fruit, or are they slow due to cooler weather than usual? When the season is done, how did that variety do for you? Should you save some seeds? Put a note in your records of what to do better next year, for selecting next year’s purchases, how many to plant. Also, jot down where you got that transplant or the seeds. 

Successive Planting

If you have poor or fungi infected soil, two plantings may make sense. The first planting may not last long depending on whether you planted a resistant variety or not. A later second planting, when the soil has heated and dried, may be more successful. To help keep the soil drier, use an open mulch like straw, only 1″ is best, for airflow. 

Planting smaller shorter fruited varieties is good early on. A month or two later you might plant long varieties that need good heat to make those big babies! 

Pollination! Or, Why do my cucumber plants have flowers but no fruit?

Unlike tomatoes that have both male and female parts in every flower, the cucurbits – squash, melons, cucumbers, have male flowers and female flowers. Somehow the pollen must be transferred. And, complete pollination is a must! Without it you may get deformed cucumbers, slow growing cucumbers or no cucumbers at all! With good pollination you can get more and larger cukes!

NMSU says: The female flower cannot produce the pollen needed to cause the fruit to develop and is dependent upon insect (or human) pollinators to transport the pollen from the male flower. The male flowers begin forming [a week or two] before the female flowers form. So, it is possible to have cucumbers blooming, but not producing fruit.

When skies are gray, it’s rainy or it is super windy, some pollinators don’t fly. Hand Pollination is easy! Daub that Q-tip or mini brush on the male flower’s anther (the stem is shorter and has no baby cuke forming under the flower – sometimes they grow in clusters where the females grow singly) then roll it onto the female’s stigma at the center of the flower! Or break the male flower off, remove the petals and do it direct! Don’t shake it and lose all the pollen before you introduce it to that girl flower! One can do several females.

Use only fresh male flowers. Flowers open in the morning. The females are only receptive that day and pollen is only viable that day. If you are doing a few it’s quick. If you have a lot of cukes, it’s going to take some time. But if you love cucumbers, it is so worth it! Do squash and melons the same way!

SFGate says: If pollination is a problem each year for your cucumbers, choose parthenocarpic varieties. Parthenocarpic varieties produce only female flowers and do not need pollination to produce fruit. This type of cucumber is also seedless.

Watering/Mulch  Compost   Fertilizer  Sidedressing

Cucumbers have short roots and need consistent water, kept moist, to never dry out. Pick first, water afterwards. Avoid wetting the plants and water in AMs if possible to avoid mildew. Plant mildew resistant varieties like Diva. Apply your baking soda mix to alkalize the leaves. Some say most granular fertilizers leach from the soil rather quickly due to watering. That is why the instructions say you should reapply periodically through the season, even once a week. Time release pellets do better. But adding organic material, compost, to your soil not only adds nutrients, it loosens the soil, attracts worms and other soil building critters and helps your soil retain moisture and nutrients.

Feed your cukes when they first begin to run (form vines and sprawl); again when blossoms set. A big vined short rooted, long fruited variety of cucumber, in a long summer is a heavy feeder, so some gardeners recommend to fertilize once a week! A small fruited, small leaved patio type container cucumber may need little to no feeding.

Since Cucumbers are short rooted, be very careful if you dig in fertilizer or compost. Dig only on one side so as not to break off all the tiny surface feeder roots. Better to add a 1″ layer of compost, some worm castings if you have them, in the planting basin, cover with straw and water well. Foliar feeding mixed teas feeds the whole plant with no harm to the roots at all! Do both the compost and foliar!

Fruits will be aborted during dry spells and very hot weather. Keep your plants watered, moist, regularly, and don’t worry if your plant temporarily stops flowering and producing. When the weather cools, you will be back in business!

Common Diseases

Mildew is #1. Plant leaving plenty of space for air circulation. Apply your baking soda mix. Drench under and upper sides of the foliage of young plants to get them off to a great start! Do this the same or next day if transplanting. A super combo is 1 regular Aspirin dissolved, a 1/4 cup nonfat powdered milk, heaping tablespoon of baking soda, a teaspoon liquid dish soap per gallon/watering can. Reapply every 10 days or so, and after significant rains. Not only is prevention so much better than after mildew has set in, but this mix stimulates your plant’s growth! IPM on Powdery mildew

The worst diseases, spread by Cucumber Beetles, are the Wilts, Fusarium and Verticillium. Please see Wilts & Cucumber Beetles, Tomatoes & Cukes! for the details, prevention and treatment.

Common Pests

Cucumber Beetle Western Striped SpottedStriped/Spotted Cucumber Beetles are the nemesis of Cucumbers. Squish. Cucumber Beetles get in cucumber, squash and melon blossoms. They aren’t picky. They are yellow greenish with black stripes or dots about the size and shape of a Ladybug. They are cute but are the very worst garden pest. They carry bacterial diseases and viruses from plant to plant, such as bacterial wilt and mosaic virus, deadly to cukes. Radish repels them, is a champion plant, a hero of the garden! Plant enough radish for you to eat and to let others just grow, be there permanently or at least until the beetles are done, gone. IPM data

Squash Bugs like your Zucchini and other squash, cucumber and melons. Plant WHITE potatoes among these plants to repel the bugs. You will get two crops instead of just one! IPM info

Whitefly infestations leave a parasitic fungus called black sooty mold, and that attracts aphids/ants and aphids add to the black problem. Hose ‘em, several days in a row to get rid of them, being sure to get under the leaves! Sprinkle the ground with cinnamon to repel aphid-tending ants. Remove any yellowing leaves throughout your garden that attract whiteflies. Water a tad less. Remove unhealthy leaves that may lay on the ground and harbor pests or diseases. Thin some leaves away to improve air circulation. IPM on Whiteflies

Bill Finch has written a detailed, educated and humorous account about using summer horticultural oil on whiteflies!It’s worth the read.

Maturity

Most cucumber varieties will start to bloom in about 60 to 65 days after they germinate. They have male and female blooms on the same plant. Only the female bloom produces fruit. Insects are necessary for cross pollination. Grow lots of bee food! If it is necessary to apply insecticides it is best to apply them as late in the afternoon as possible, when bees are less active. Parthenocarpic varieties having all female flowers, don’t need bees. 

Harvest & Storage

Cucumber Pickles And Dill Jars

Mexican Gherkins/Mouse Melons, are ripe when they fall to the ground! Lemon cukes are best eaten while still young and pale green. Other Cucumbers mature rapidly and once in production check every other day for ones ready to harvest. No storing on the vine or your plant thinks it’s done and stops producing. Cut, clip or carefully twist off while holding the vine. Cukes are old if they are large, puffy, dull and yellow. Use care not to step on vines during harvest. 

Pickles are the only real way of storing cukes, and there are the cuke varieties that are specific for that purpose! Probiotic pickling is the healthiest way of doing it. 

Cucumbers are another room temp veggie. University of California, Davis, says cukes are sensitive to temperatures below 50°F. They thrive and last longer at room temp. However, cucumbers, eggplant and peppers can be kept in the refrigerator for 1 to 3 days if they are used soon after removal from the refrigerator.

Seed Harvest, SeedSaving, Inbreeding Depression.  When, Seed Saving Process, Viability

If you are in a short summer cool climate, don’t have a long enough summer to save seed, buying seed may be your only option.

Parthenocarpic means your plant produces without pollination, makes NO seeds. Like with hybrids, saving seeds is not an option. However, there are reports of saving seeds from parthenocarpic plants! Some flowers do get pollinated. Soak the seed like usual, keep only the sinkers that look the most like your original seed! You might not get many, but probably enough!

If you have non parthenocarpic varieties and want to save cucumber seed, plant only one variety! They cross breed like crazy! Experienced home seed savers can grow more than one variety at a time in a single garden by using hand pollinating techniques. If you don’t hand pollinate, separate two different cucumber varieties by at least 1/2 mile to ensure purity. Inbreeding Depression, reduced vigor due to breeding related plants, is not usually noticeable in cucumbers. Seeds should be saved from at least 6 cucumbers on 6 different plants.

You may ask what if I plant non and Parthenocarpic varieties together? Parthenocarpic cucumbers grow fruits without pollination, developed for commercial greenhouse production – no bees. As a home gardener, if pollinated they will have seeds. If you don’t mind seeds, then interplanting is not a problem. But these seeds will be hybrids. Experimenting can be fun, or disappointing if you want what you had before.

Saving the seeds of Cukes, Eggplant, Melon, Pepper, Squash, Tomatoes, and Zukes is super easy.

Leave the best or last of your cukes to get old on the vine to reap all they can from the Mother plant. Leave them at least 5 weeks after the eating stage, until they have turned a golden color. Now is the time we want those old large, puffy, dull and yellow ones! In northern areas the first, light frost of the season will blacken vines and make cucumbers easier to find. Undamaged fruits can be stored in cool, dry place for several weeks to finish ripening. 

Slice your cucumbers lengthwise and scrape seeds out with spoon. Put them in warm water no more than two days. Scrape any scum off. Let the contents settle and begin pouring out the water along with pieces of pulp and immature seeds floating on top. Viable seeds, sinkers, are heavier and settle to the bottom of the jar. Repeat this process until water being poured out is almost clear and clean seeds line the bottom of the container. Pour these clean seeds into a strainer that has holes smaller than the seeds. Let the excess water drip out and invert the strainer onto paper towel or piece of newspaper. Allow the seeds to dry completely (usually a day or two). Break up the clumps into individual seeds, label with date and variety, store in a packet or plastic bag. Check them in a week or two to be sure there is no mold or any insect infestations.

The drier the seeds, the longer they will store ~ about 5 years for cucumbers, 2 – 10 maybe. 


Cucumbers are easy to eat! 

Cucumber Open Sandwich Dill Garnish

Some cucumbers simply never make it home from the garden. Next best fresh is in a tasty greens salad!

Eat cukes and yogurt! Raita, an Indian dish, is pretty and a very nice cooling summer dish. It can also be used as a sauce over falafels, as a veggie dip or salad dressing! Chicken, lettuce & cucumber slice sands!

Make a pale green egg salad with fresh minced basil, green onions, and crunchy cucumbers. Tuck it into pita pockets. Mmm…..

In Asia cucumbers are often stir-fried and are quite tasty. Give it a try! Toss cold noodles with sauce, cucumber, and scallion or coriander. Sprinkle noodles with sesame seeds.

How about a delicious Pineapple Cucumber Smoothie?! Add blueberries for blue, Strawberries for pink! Or do Cucumber, Apple & MInt! With Kale. Watermelon! Do a flavor a day – just add Cucumber!

  1. Add cucumber, pineapple, frozen banana, light coconut milk, water, lime zest, lime juice, greens, and ice cubes to a blender and blend on high until creamy and smooth, scraping down sides as needed.
  2. For a thicker smoothie, add more ice. For a thinner smoothie, add more liquid of choice. …

Pickles are prime! Do probiotics for the very best nutrition! Add carrot sticks, hot peppers, garlic, dill, whatever tickles your tastebuds!

FYI the inside of a cucumber can be up to twenty degrees cooler than the outside temperature! This is where the saying cool as a cucumber came from.

Stay cool!

The Green Bean Connection newsletter started as correspondence for the Santa Barbara CA USA, Pilgrim Terrace Community Garden, then became this blog too! All three of Santa Barbara city community gardens are very coastal. During late spring/summer we are in a fog belt/marine layer area most years, locally referred to as the May grays, June glooms and August fogusts. Keep that in mind compared to the microclimate niche where your veggie garden is.
