Strawberry Tips for Tasty Super Berries!

  • Strawberries are in the Rose family.
  • The average berry has 200 seeds, the only fruit whose seeds are on its exterior surface!  The seeds are really the fruit!
  • Usually grown from runner daughters, they will grow from seed.  Just throw down caps you bit the berry from.  Sooner or later, you will have a plant you didn’t ‘plant.’  Strawberry seed saving is simple.
  • Eight out of 10 strawberries grown in the U.S. are grown in California!
  • Strawberries came in second to blueberries in the USDA’s analysis of antioxidant capacity of 40 fruits and vegetables. They are also rich in dietary fiber and manganese, and contain more vitamin C than any other berry.

When do I plant strawberries?  Not now, NOVEMBER 1 to 10!  Yes, it’s that specific for winter chill at the perfect time!  They start producing runners now, but cut them off until early July!  Then let them grow, and cut off the new baby plants mid October for November planting.  Or, just let them grow to fill spots where, for one reason or another, a plant has gone missing, needs replacing, and/or another could fit in.  When those needs are taken care of, cut off the rest of the runners.  These runner plant babies will grow so fast you will be getting berries from them late summer and fall if you have everbearers/day neutral types!!

My plant isn’t producing….  

Variety
 – If it is an everbearer, day neutral, variety it will produce almost all year.  June/spring bearers put out a prolific batch in June, then it’s over.  No amount of care or feeding is going to make that plant have berries after June.  Sorry.  Best to get the varieties your local nursery carries.  Or talk with them about special ordering well in advance, so they can get the ones you want.
Temps – cold weather slows down pollinators.
Shaded – believe me, strawberries like all-day sun!  If you are going to tuck them in among other plants, be sure to put them on the sunny side!
Hungry – think about it!  A strawberry plant is often pumping out several berries at a time!  They are using up soil nutrition, so feed them!  Try a light solution of fish emulsion/kelp every other week over some sprinkled seabird guano or a well aged manure.  Give your strawberries a little fertilizer in the 0-10-10 proportions; that’s lots of phosphorus and potassium for strong roots and uptake of nutrients, blooms and fruits!
Water – don’t let them dry out, they will stop producing.  This month they tend to grow more leaves, send out runners.  Clip off the runners for now, so they don’t take your plant’s energy away from producing berries, unless you want more plants right away.
Mulching is good.  They love pine needle mulch, if you have some about, because they prefer slightly acidic soil.  Drape your berries over pine cones to keep them off the ground, out of the slug zone.
Age – First year plants and 3rd year plants don’t produce as well.

My berries are really tiny! 
Strawberry varieties vary from mammoth chocolatiers, to midget but mighty tasty alpines.  If it isn’t a variety issue, it may be diseased.  See below please.

Misshapen berries or split in two sections with a hole in the center 
Irregular watering  Your berry grows fast when it has water, then is restricted when it doesn’t….
Western Tarnished Plant Bugs,
feed on the flowers and developing surface seeds that stimulate growth causing misshapen berries, hard clusters of yellow seeds on the tip of the fruit.  Clean up debris.  Once you see this, you are too late to prevent it any further.  Bummer.  UC Davis IPM Integrated Pest Management on Lygus Hesperus.  Image of typical cat-faced berries.
Pollination Strawberry flowers are usually open and attractive to bees only a day or less.  Temperatures below 60F, low night temperatures, & high humidity result in inadequate pollination, low yields of small or misshapen fruit.  Strawberries require multiple pollination for perfect fruit formation. Generally, as the number of pollinator visits increases, there will be an increase in fruit set, number of seed per fruit, fruit shape, and fruit weight.  ABOUT BEES:  per NCSU ‘Bees rarely fly when the temperature is below 55°F. Flights seldom intensify until the temperature reaches 70°F. Wind speed beyond 15 miles per hour seriously slows bee activity. Cool, cloudy weather and threatening storms greatly reduce bee flights. In poor weather, bees foraging at more distant locations will remain in the hive, and only those that have been foraging nearby will be active.  Pumpkin, squash, and watermelon flowers normally open around daybreak and close by noon; whereas, cucumbers, strawberries, and muskmelons generally remain open the entire day.’  So if the weather isn’t right THE DAY OR MORNING your flower opens…..

Whole plant has yellow leaves.  The most common cause is nutrient deficiencies due to overwatering.  Overwatering causes poor root growth making it difficult to move enough water to the leaves during hot weather.  Lay back on watering; give your babies some Nitrogen –fish emulsion/kelp.

Strawberry Pests
Pecked   If birds are pecking your berries, put bird netting or a wire dome over them.

Rebecca & David Barker, Pilgrim Terrace Community Garden, Plot 41, staked the chicken wire in place, push it up to harvest, down to just the right height when done!

Holes in them, Chewed  Silvery slime trails are the giveaway!  Use the pine cones to drape your berries over to keep them off the ground.  Put down some Sluggo or the like, to kill off night-time nibblers, slugs, snails.  Harvest regularly before the berry gets soft and smelly, just before the buglets are attracted!  Those little black pointy worms?  I’m trying to find out what they are.  If you know, let me know, ok?!
Uprooted  Sad to say, that sounds like ‘possums, raccoon, or skunk.  They are looking for your earth worms or grubs.  Just like bunnies, these critters won’t jump a low barrier.  They just go around it.  So install a foot tall perimeter of wire pieces, black plastic plant flats, old trellis parts, whatever you have around, or go get something that looks good to you so you will be happy.  Relocating the critters is a good choice because, they do have children, that have children, that…

Strawberry Diseases  StrawberryPlants.org for full list of diseases.  Here’s a link to the 3 Most common leaf diseases with images.

Angular Leaf Spot – exactly that.  Spotted leaves.  A cosmetic problem until it isn’t.  Your plant will produce, but it won’t thrive.  Spread by water, harvest before you water, water under the leaves, remove badly spotted leaves, don’t use them as mulch, wash your hands before going on to another plant.
Strawberry Blight – the fungus is often confused with angular leaf spot, overwinters in old leaves, remove them.  Remove old leaves from runner plants before setting.  All day sun, well-drained soil, in an area with circulation, equals less fungus.  For good air circulation, plant far enough apart, remove weeds, remove, replant and/or give away runner baby sets.  Plant resistant varieties for your area of your state.  Discussion of SoCal varieties.  When you buy new plants be sure they are certified from a disease-free nursery.  If you use a fungicide, spray the underside of leaves as well as the tops.

Successful SoCal varieties!

Chandler is the most widely commercially grown strawberry in California.  High yield, early producer, large southern berry.  It’s a June bearer, so if you want year round supply, this is not your berry.
Seascape is an ever-bearing, big day neutral, all year strawberry, harvests are more abundant in late spring. High yield, resistant to most diseases except leaf spot.  Reliable producer in fall, performs well in hot, dry climates.  Berry is bright red inside and out!
Oso Grande Another June bearer, high yield big berry, good in warm climates.

Tomatoes & the Wilts – Part 1

Wolf Peach!!!!  Did you know – our tomato originated in South America and was originally cultivated by the Aztecs and Incas, came to Europe in the 1500s.  People were warned not to eat them until the 18th century!  Wolf Peach comes from German werewolf myths that said deadly nightshade was used to summon werewolves!  ‘Tis true, tomatoes are of the deadly nightshade family, and does have poisonous leaves.  But you would have to eat a LOT of them to get sick!  But they are not good for dogs or cats!  Smaller bodies, right?

Tomatoes & the Wilts – Part 1

Tomato - Healthy SunGold!

Tomato – Verticillium Wilt

Above on the left is a very healthy Sun Gold cherry tomato and happy owner.  On the right is a verticillium wilt fatality, not old age.  Almost all of us have had tomato wilt fatalities.  Very sad to see, disappointing and frustrating as XXX!  Tomatoes are pretty dramatically affected, but many plants get the wilt, including your trees, shrubs and roses.  Veggies affected are cucumber, eggplant, pepper, potatoes, rhubarb, watermelon, artichoke, beet, broad bean, strawberries, raspberries.  Cool, damp weather, like we had here in Santa Barbara area ALL last summer, referred to as the ‘May grays’ and the  ‘June glooms,’ is the worst. 

The leaves fold along their length, the stems get brown/black spots/blotches on them, the leaves turn brown, dry and die.  It is a fungus in the soil that is also windborne.  There may be too much N (Nitrogen), too much manure – lots of gorgeous leaves but no flowers.  That’s an easy fix, add some Seabird (not Bat) guano to restore the balance, bring blooms, then fruit.  The wilt is tougher.  When the toms get about a foot tall, STOP WATERING!  Remove weed habitat and don’t mulch.  The fungus can’t thrive in drier soil. Water the toms’ neighboring plants, but not the toms.  Tomatoes have deep tap roots and they can get water from below the wilt zone.

It is better to pull infected plants, called the one-cut prune, because their production will be labored and little compared to a healthy plant that will catch up fast in warmer weather.  And you will be more cheerful looking at a healthy plant.  Heirlooms are particularly susceptible, so get varieties that have VFN or VF on the tag at the nursery, or are a known VFN variety.  The V is for Verticillium, the F Fusarium wilt, N nematodes.  Ask a knowledgeable person if the tom doesn’t have a designation, or check online.  It’s just a bummer when plants get the wilt.  If you are one who removes the lower leaves and plants your transplant deeper, don’t let the lowest leaves touch the ground. When your plants get bigger, cut off lower leaves that would touch the ground BEFORE they touch the ground or leaves that can be water splashed – some say take all up to 18″ high!  The wilt gets into your plant through its leaves, not the stem.  Don’t cut suckers (branches between the stem and main branch) off because the cuts can be entry points for windborne wilts.  Wash your hands after working with each plant with the wilt so you don’t spread the wilts yourself.

There’s little you can do for/to the soil to get rid of the wilt.  The only method I know that most of us can afford is Solarization.  Put black plastic tightly to the ground during a couple weeks of heat to kill it.  Problem is twofold.  1) That would be high summer to get that heat, so you can’t have your summer crop in that area.  If you have enough space, it’s doable.  If you only have a small space, that means no toms this year.  2) We are coastal and the temp needed to kill the wilt isn’t maintained over a two week period.  Sigh.  So we do our best, resistant varieties, little water, removal of lower leaves, remove infected plants.  A lot of smart local farmers dry farm tomatoes, and it’s water saving. 

You can use straw bale planting, or make raised box beds and fill them with soil that isn’t infected with the wilt.  That can help for awhile.  Here’s a link to my Green Bean Connection blog post on Plant a Lot in a Small Space that has a bit on hay/straw bale gardening!  It’s about 2/3s down the page, with link for instructions!  But.  Not only are the wilts soil borne, but airborne.  That you can’t do a lot about except ask everyone with infected plants to remove them.

Now IS still a good time to start your seeds, especially your true heat lovers – eggplant, limas, melons, okra, peppers and pumpkins, and for you SoCal coastal marine layer gardeners, tomatoes!

Beautiful Scarlet Runner Bean Seeds

When you start them, for your sanity, label your seedlings with their name and date!   

Hmph.  How hard could it be, soaking seeds?!  It isn’t, but it turns out there are lots of options and some specifics for better results!

Whether you only soak your seeds, or go on to presprouting, is your choice.  For me, I found once they started sprouting, growth was rapid!  At that stage, they can’t dry out or be too wet and rot, so you have to be ready to plant!  Also, it is more difficult to very carefully plant sprouted seeds.  They are delicate!  So if you are at all bull-in-the-China-shop like I am, it may pay to only presoak!

The main arguments for seed soaking are not only for a speedier garden [Sprouted seed will grow in soils too cool for germination, YES!, but also for more complete germination of all seeds planted. You can get germination results in 3 to 4 days, while without pre-soaking it may take 2 weeks of unfavorable germinating conditions, and you may get none.  Whether you plant directly in the ground, or for those of you at Pilgrim Terrace planning on using the greenhouse, here is some very useful info on seed soaking!

The Harrowsmith Country Life Book of Garden Secrets, by Dorothy Hinshaw Patent & Diane E. Bilberback:

The seed coat that surrounds the living seed sometimes does more than just protect it. The seed coats of many plants contain chemicals that inhibit germination of the seeds. This keeps them from germinating too early or when only briefly exposed to moisture. Some gardeners who are interested in rapid germination soak and wash their seeds to get around these germination inhibitors.

Some types of peppers, such as jalapenos, may germinate more rapidly if soaked in a couple of changes of lukewarm water before planting.

Beet and chard seeds also have a germination inhibitor; these strange-looking lumpy “seeds” are not really seeds at all but dried-up fruits of the plant, each of which contains several seeds. (That’s why beets and chard always need to be thinned.) The hard fruit covering contains a germination inhibitor, but if you soak the seed (fruit) overnight, it will absorb too much water, and you will still have poor germination.Seed coats play other important roles in the lives of plants. They regulate how much oxygen, water, and light the seeds receive.

You may have planted beans or corn in soil that was very moist but cool and were dismayed by subsequent poor germination. The seed coats of these crops can allow water to rush into the seeds too quickly, as with beets. This rapid water uptake can damage the tender cell membranes, permanently harming a young seedling so it grows slowly or preventing germination altogether. This process has been termed imbibitional shock, or soaking injury. Soaking injury can occur at any time with some crops, but cold temperatures make it worse.To avoid soaking injury, you can allow the seeds of sensitive crops such as beans, beets, and corn to soak up water gradually before planting them in the garden. This method is called seed moisturization.

One way to do this is to place them in moist vermiculite for eight to sixteen hours before planting. An easier method for most home gardeners is to place damp paper towels on a sheet of wax paper, sprinkle on the seeds you want to hydrate, and roll up the towels with the wax paper on the outside. Leave the seeds inside the paper for eight to sixteen hours at room temperature. Don’t let them sit for more than nineteen hours, or the delicate seedling root may begin to penetrate the seed coat, and you could damage it during planting.

Things to know plucked from the web….  

Start with viable seed.  Check the date on the seed pack to see when it was packaged for.

It won’t do you a bit of good, for example, to presoak lettuce seeds and expect them to germinate in a soil temp of 87 degrees, as they prefer a cooler-temperature. So start your pre-soaked seeds at the temperature and time you generally plant. Pre-soaking just gives you faster performance under normal conditions.

There are huge variations in the length of time people soak their seeds!

  1. Tomato and Pepper seeds are soaked 6 hours, no more that because they can suffocate from lack of air.
  2. overnight in tepid water. That is water that is warm, but not hot. I make sure that the seeds are covered at least twice their size with water. I don’t add anything to the water, but when planting them, I do water them in with manure tea.
  3. Soak them for 12 hours in compost tea, then rinse & drain. Rinse & drain each day, keeps the seeds moist until you have roots.  With beans, the roots emerge from the scar.  Plant the seed endwise, the root pointing down.  Plant roots and shoots at the soil surface, the bulk of the seed below the soil mix surface.  Keep moist.
  4. Soaked in tepid well water for six hours. The water was then poured off and the seeds were rinsed a couple times a day with some misting in between. The seeds were planted once they had visible roots.
  5. 12 hours in water, then drain and leave for 12 hours, then keep repeating the process until they split their skins and start showing a root. It normally only takes 2 or 3 days and then I plant out.
  6. Bean seeds may split if soaked for more than an hour or two. However, even this short soak will speed up germination
  7. When legume (peas/beans) seed coats split, the seeds may lose vital nutrients and fall prey to disease fungi when planted.  Drain them after they have been submerged for an hour.
  8. I do think I’ve oversoaked bean and pea seeds in the past, almost to the point where they are falling apart, and that it has weakened them. The soak time would depend on the size of the seed I would think, but never more than a few hours.
  9. I let them soak ‘til they are big and full, or ‘til they start to sprout a small root. Corn, beans, peas, squash (some) and pumpkins. Then I gently place them in the ground.  [Tweezers, please?!]
  10. OKRA !!!! (48 hours)  Or… I presoak my okra seed in 1 pint of warm water containing 1 tablespoon of household bleach to pre-soften the seed for 24 hours before planting.
  11. Cucurbita (cucs, luffas, melons, squash) seeds only needs to be soaked to loosen up the shell. Gourd seeds in particular are very tough and some people even scratch the sides of tips (scarify) to make it easier to germinate. I soaked them a little and also wrap them in wet toilet tissue before planting. This will help to keep them moist.

The soaking solution varies…see compost tea, manure tea above.  And what about worm tea?!

  1. Last year I soaked my bean seeds in a kelp solution before planting and they sprouted in about 2 days.
  2. I would never use bleach in the soaking solution. If you are worried about contamination, try soaking in chamomile tea or 3% hydrogen peroxide instead. If the seed is purchased, I wouldn’t bother.
  3. Hydrogen peroxide, both in soak and rinse solutions:1 oz. of  3% H²O² to 1 pint of water.  Sprouts come up faster.  Some people have reported 3/4″ sprouts in 24 hours.   

When you plant the seedlings dig the hole and spray it with peroxide. Wet it good and then wet the roots of the seedlings or small plant.   

The vegetable that gave me a problem was the cabbage. I was determined to conquer the cabbageworm. Years ago I sprayed the cabbage plants with peroxide to no avail. This year I soaked the cabbage seeds before planting them. There were no signs of the bug until the cabbage plants were almost full grown, then I poured about a quarter of cup of 8% peroxide over the cabbage, letting it flow down into the layers of the leaves. That stopped the cabbage bugs.

GARLIC TIP: Deciding when to harvest your garlic crop is not an exact science. In the USA and much of Northern Europe garlic is usually harvested in the summer months. The harvesting begins in July and picking can continue all the way through August. Check out this YouTube short: http://www.youtube.com/watch?v=3zcZmDdfano

June blooms mean tasty veggies!

The first tomatoes have now been eaten at Pilgrim Terrace Community Garden, and one bell pepper!

June is not so much a planting month as a maintenance month and getting those first veggies!  You can continue to plant more rounds of your summer plants, especially the ones that don’t have continuous production like indeterminate tomatoes that will produce all season long.  Stoke up your soil, replace plants that didn’t make it, that are done already – mature or bolted chard, cilantro, lettuce, arugula, beets, or are ailing. 

Special Strawberry Tips!  Don’t let them dry out, they will stop producing.  Mulching is good.  This month they tend to grow more leaves, send out runners.  Clip off the runners for now, later we will let them grow.  Give your strawberries a little fertilizer in the 0-10-10 proportions; that’s phosphorus and potassium for strong roots and uptake of nutrients, blooms and fruits!  They love pine needle mulch, if you have some about, because they prefer slightly acidic soil.  Use the  cones to drape your berries over to keep them off the ground, away from chewing creatures. 

Same as last month….

Water deeply, specially as each plant needs.  That’s more frequently for short rooted beans, cucs and strawberries, thirsty lettuces.  Irregular watering = funky shapes; too dry = bitter, production can stop.  Water seeds/seedlings daily.  If they dry out once, they’re dead.  Immediately after planting and watering your new little plant in, sprinkle on some Sluggo.  Sprinkle Sluggo just before your seedlings come up.  Tiny tender plants are irresistibly delicious!

Side dress/fertilize, especially if leaves are looking pale or your plant is puny or slowing down.  Blood meal for a quick fix, otherwise, compost, a little manure raked in, liquid kelp & fish emulsion mix.  Epsom salts for your peppers, once when they bloom and again ten days later. Go very gently with beans, tomatoes and strawberries.  These are not leaf crops, you want fruit!  Too much N (nitrogen), and you get a lot of leaf, little production.  If your planting bed was too rich or you over fertilized, bee bop on out to Island Seed & Feed (if you are in the Santa Barbara CA area) and pick up some Seabird Guano (NOT Bat Guano!).  The Seabird Guano is high in phosphorus, promotes healthy root growth, greatly increases the number of flowers, increases the available phosphorus in the soil and enhances beneficial bacteria activity in the soil!  It is good to use generally just before your plants flower or you see the first flowers!  This inexpensive treatment is a wonder!  Imagine how many beans, strawberries….Yes! 

Now plant heat tolerant and slow bolting varieties of cilantro, and lettuces – Nevada, Sierra, Jericho, Slobolt, Black Seeded Simpson.  Bolting, a natural maturing phenomena – the center of the plant shoots up and forms flowers, is caused by accumulated light hours, warm temps, and water stress.  Another thing to find is varieties that are leaf tip burn resistant.  Might plant them under a bit of a canopy or in the shade of a larger plant?  As your big plants get up, clear the lowest leaves and tuck some lettuce or dandelion greens underneath?

Harvesting is not just for food!  Just like deadheading flowers, when you harvest, they keep coming!  Eat little zuchs flowers and all!  Pull beans and cucs continuously while they are young and tender.  No storing on the vine, or you plant will think it is done!  Continue to harvest your broc side shoots.  Once it goes to flower (they are edible – sprinkle them on your salad!), no more side shoots.                                                      

* * Plant special flowers, herbs, or veggies for summer Hostess gifts!  Friends getting married in June?!  Why not give them plants for their new garden together?!  How symbolic!  Plant a little extra all the time for ready gifts for any occasion!
