Pollinator Plant Cosmos Drought Tolerant Long Season Ca Native Bees

Lovely many colored drought-tolerant Cosmos blooms spring through first frost!

The most fabulous choices to grow are a diversity of flowering multipurpose companion plants with your veggies! If that includes being a native plant, hallelujah! 

Companion Planting maximizes your connections!

Companions plants may be other vegetables, like Radish! It is grown for the bulb, can be planted as a living mulch understory, can be let to grow up among cukes and zukes to repel cucumber beetle, is a trap for flea beetles, makes lovely edible flowers! We eat Cilantro leaves, it repels aphids, it’s flowers attract pollinators, the seeds become Coriander on your spice shelf. 

Some companions are colorful! Calendula! Chamomile is bright beauty. Arugula and radish flowers are delicate and detailed! Some flowers are total dainty princesses – cilantro, carrot and celery, the three Cs! Let arugula, cilantro, chamomile, a carrot or two, and a celery go to flower summer through fall to bring bees, butterflies and beneficial insects – pollinators! Besides being beautiful and having lovely scents, let them seed out for seeds for next year’s plantings, to share at the seed swap, give as gifts! Carrots love being with cilantro and chamomile, and chamomile improves the flavor of any neighboring herb!

And what if they are not companions?! Grow beauty for the pollinators just because you love beauty and your special little friends! Flying insects are the most common pollinators. From Cornell: Native bees are two to three times more effective than honeybees! A special note about the importance of Bumble bees! Honey bees DON’T pollinate tomatoes, peppers, potatoes, eggplant or blueberries, but bumble bees DO! Bumblebees do what is called buzz pollination, sonication! Please see all about it in Sue Rosenthal’s post at Bay Nature! See the PBS Bumblebee Buzz Pollination video!

Be careful with those lovely hybrids, especially ‘double-blooms.’ A slight change in scent or shape and your pollinator may not be able to recognize them.

Design for Habitat and No Pesticides!

When you are thinking where to put things, select permanent spots for herbs, gateway points for flowers and edible flowers! Designate a permanent patch for year round flower habitat for bees. Cilantro is both tasty and has lovely feathery leaves and flowers in breeze, great pollinator food. Chamomile is downright heady scented on a warm morning. Comfrey, Knitbone, is both medicinal, healing (arthritis/bones), and speeds your compost, is high in soil nutrition. Poppies are beautiful; humble white Sweet Alyssum is dainty and attracts beneficial insects. Calendula traps aphids, whiteflies, and thrips! Marigolds are brilliant and called the workhorse of pest deterrents! Cosmos is cosmic! Breadseed Poppies will literally have your bees rolling in pollen!

Prairie Nursery in Westfield WI says: Pollinators are attracted to blooms that fit the pollinators’ physiological traits – specifically the length of their tongue. Some bees are generalists, flitting among flowers to drink nectar and collect pollen from many plant species. Flat or shallow blossoms, such as asters or coreopsis, attract a variety of bee species. But long-tongued bees will be attracted to plants with deeper nectaries and flowers with petals that form long tubes. The inclusion of a variety of floral shapes [and sizes] attracts a more diverse array of pollinators.

Grouping plants in clumps of three or more attracts bees to the plants and allows them to forage efficiently. And don’t forget the water. Pollinators get thirsty while they are working in the sun! They like shallow water sources. A shallow birdbath with stones in it is perfect!

Farmers are planting wildflower rows! See Stripes of Wildflowers! The stripy fields have been planted across England and other countries as part of a trial to boost the natural predators of pests that attack cereal crops and potentially cut pesticide spraying! Plant flowers among, alongside, your veggies! In fact, plant your flowers right in the center of things where they can serve several plants at once! Make that a short walk, or fly, for your beneficial insects! You may not plant stripes six metres wide, but do grow plenty of flowers the length of your area!

Pest Pesticides Reduction Flower Stripes Habitat in Fields

Current UCDavis research published Dec 18, 2018 says “Planting wildflowers is a key strategy promoted nationally to support wild and managed bees,” said Williams. “Successful adoption of these plantings in agricultural landscapes will require that they not only support pollinators but that they also avoid supporting too many pests. Plant selection going forward will need to balance multiple goals of pollinators pest management and other functions. This research is a first step on the path to identifying plants that will meet these goals.”

All Season Support! Text for images from UCDavis Arboretum post for native California bees! 

Some bee species are active all year, others only in April and May, still others in July and August, and all need food! New queens are born in the fall, and after breeding they may find a place to hibernate for the winter. When they emerge in spring, they need nectar and pollen sources—or they can’t start their colonies.

Spring

California poppy, Eschscholzia californica is technically an annual, but they will “perennial-ize” by sprouting the following year from their roots and lower stems or by re-seeding. Look for sweat bees scrambling around the bottom of the flower and covering themselves with pollen.

Pollinator Gaillardia × grandiflora Blanket Flower

Summer

Blanket flower,  × grandiflora is a colorful daisy-type flower popular with a number of native bees. In the Valley they attract long-horned bees like Melissodes which can be easily observed collecting nectar and pollen from the showy orange and yellow flowers. This plant may be short-lived in heavy soils. Image by Cerena Childress, Pilgrim Terrace Community Garden

Pollinator Plant Germander Sage, Salvia chamaedryoides Native CA Bees
Fall

Germander sage, Salvia chamaedryoides blooms with beautiful dark blue flowers from late spring to early summer and again in fall. It is a primary nectar source for a number of bee types. Male carder bees may be most noticeable as they set up territories around flowering patches and knock into other bees that enter their area. Deadheading spent flowers in early summer will help the blossoms (and the bees) return in fall.

Goodwin Creek lavender, Lavandula × ginginsii ‘Goodwin Creek Grey’ hybrid lavender is a tough and long-blooming sub-shrub that can be used to provide winter structure to your pollinator planting. Blooming early and lasting into summer, it is popular with large carpenter bees and a range of other smaller bees for its nectar. It can be pruned to shape, to increase branching, or to keep a compact form. Image at UCDavis Arboretum

Grow host plants for butterfly & moth caterpillars too! Some are quite particular, even to only one kind of plant.

Other special pollinators!

Don’t forget the other littles! Butterflies, midges, beetles! Wasps, ants and flies, even slugs! Some of them will make you more happy than others, but thank them too for pollinating!

Bird pollination even has a name, Ornithophily! In the US, hummingbirds are key in wildflower pollination.

About 87% of flowering plants are pollinated by animals. These include wild flowers and those used by people for food and medicine. While many ground plants benefit from small mammals’ pollination, some flowering trees rely on similar relationships with tree-dwelling or flying mammals. Bats are probably the best known mammal pollinators. Hundreds of plants rely on these busy, flying nectar lovers to spread their pollen at night.

The ‘little dragons,’ lizards and skinks, not only pollinate, but eat insect pests!

Where your pollinators live!

Flowers are much more than a pretty face! They are habitat. That means food and shelter, moisture – the morning dew, and for many wild bees, a place to sleep at night! You don’t always see them because they generally get up earlier than Honeybees.

First and foremost, just because your flowers are done, doesn’t mean beneficial insects don’t still need food and living quarters. Be more conscious about planting permanent habitat for them. Plus, if you have year ’round habitat, they will be ready to work for you as soon as your plants are up!

Stripes of Wildflowers says they plant oxeye daisy, red clover, common knapweed and wild carrot. Likely they carefully chose those plants for the results hoped for. This combination probably serves the majority of common beneficial predators, large to small, needed to replace those pesticides.

  • Oxeye daisy is a pretty little perennial – grows year after year, no replanting necessary.
  • Depending on your climate, Red Clover, a legume, is a perennial that has the added advantage that as they die they also feed the soil the flowers are growing in!
  • Common knapweed is a tall, thistle-like grassland perennial that doesn’t like wet areas or acidic soil.
  • Wild carrot (Daucus carota), also known as Queen Anne’s lace, is a biennial plant in the parsley family. The flower head has trillions of tiny flowers! It is perfect for smaller beneficial insects, strongly attracts Syrphid flies aka Hoverflies!

The common factor here is by planting perennials and self-seeders, there is always habitat, and no replanting necessary! Though Wild carrot is a biennial, it self-seeds like crazy, keeping a constant supply of flowers! Your choice of flowers, that insects love, that bloom all year long and are there all the time, is garden wisdom!

Honey bees have their hives, but native bees don’t. Most species of wild bees are solitary, and some 70 percent of them dig a nest in the ground to raise their young—something they can’t do if mulch is in the way. Leave a little bare ground and protect it from being stepped on! No mulch needed! They favor a slight slope or well drained site.

Install some living quarters, a bee block or bee hotel, which are available online or at some garden stores. Bee hotels are a pollinator’s paradise! Pollinators’ housing needs are hugely diverse! Bare soil, hollow twigs, big holes in trees, little holes of only a certain depth. You could also drill holes of varying sizes in a dead tree that’s still standing (if beetles haven’t already done it for you). You can easily build them yourself! They can be simple and small or a luxury condo like this one! See more!  Please see these super useful detailed tips here!

Homemade Solitary Bee House with Gourd!

Put your bee home up in March or early April! This will offer prime nesting sites for solitary bees for laying their eggs. Soon they will be buzzing, hovering and feasting about your veggie garden! Plant their favorite flower foods in time to feed them! See more about their favorite food!

Jennifer S Holland, writes for National Geographic: Learn more about organizations that support pollinators and their habitats, such as Pollinator Partnership. You can also participate in citizen-science programs for pollinators such as Bumble Bee Watch (Xerces Society), The Great Sunflower Project (San Francisco State University), Fourth of July Butterfly Count (North American Butterfly Association), and the Monarch Larva Monitoring Project (Monarch Watch).

If you have questions, one wonderful resource is the National Gardening Association! State your location when requesting information. The National Gardening Association reaches more than 7.6 million gardeners a year, and during the Million Pollinator Garden Challenge recorded on its website:

• A 25% uptick in participation in its forum, “Gardening for Bees and Butterflies.
• A 45% increase in searches relating to pollination.
• 140,000 photos of pollinator-friendly plants and pollinators uploaded.

For those of you with space for shrubs and trees, find out the best varieties to seasonally support our precious pollinators all year long! If you don’t have big space, plant your mini bloomers in containers, on your apt balcony, wherever you can! Don’t forget to plant the street strip with drought tolerant abundantly flowering native plants, buckwheat might be one! Check with your local nurseries that support pollinators, local botanic gardens, master gardeners, for the best plant choices for your area.

Compost Tea Brew for Seedlings

Some of you are pros, literally, at making teas, others of us have never done it before, but interested, even willing to give it a try.

Why? Why make teas at all? Isn’t good soil enough? If you are just making compost tea, with compost you are already using in your garden, you may not notice much results. Every time you water, aren’t you making compost tea in place anyway?! But if you make a more diverse tea, with a lot of different ingredients, and it is made just right producing a lot of microbes, you are likely to get superb results! Research shows foliar feeding is more effective than soil drenching.

A lot of summer plants are what are called ‘heavy feeders.’ They are doing business 24/7 for several months using that soil right where they are at. They can’t go walkabout seeking new soil. Plants that produce leaf crops, lettuces, chard, kale, are using up soil nutrients just as fast as they can! Plants that produce a lot of crop, tomatoes, cucumbers, squash, are feeding a big plant, foliage and fruits! Teas are a microbial inoculant that gives them a boost from leaf to root!

Teas offer increased nutrient availability!

Teas are a high grade fertilizer full of nutrients and minerals! The tea’s chelated micronutrients are easy for plants to absorb. The teas will never burn your plants. You can easily make them yourself from your own materials. You know exactly what’s in it. No chemicals, and they don’t add salt that commercial fertilizers can add to your soil. DIY! Save money!

Marvelously, tea microbes degrade toxic pesticides and other chemicals! Much better for beneficial insects, wildlife, plants, soil and humans. Your soil will come alive again as the organisms start thriving. Your soil will have greater water holding capacity, a resiliency, the aeration it needs from burrowing soil creatures.

Nutrients! Black liquid gold can feed your plants through their roots and their leaves. The beneficial microbes are fast acting and quickly absorbed. This whole plant treatment increases plant growth – more and bigger blooms, bigger size fruits and yields. The microbes produce plant growth hormones; mineralize a plant’s available nutrients, and fix nitrogen in the plant for optimal use.

Suppress diseases! When plant surfaces are occupied by beneficial microbes, there simply is no room for pathogens! The plant will suffer little or no blight, mold, fungus or wilt! That’s a huge claim! But even if it doesn’t entirely work, your plant will likely have a much improved existence for a longer period of time. Beneficial microbes compete with disease causing microbes. Go tigers! The live microbes enhance your soil and in turn, up the immune system of your plants. Your plants are healthier, more stress-tolerant.

Communi-Tea Make your own Compost Tea!

Making teas is fairly new, but is here to stay! Nowadays we know more about microbe power, soil and plant structures and processes. Researchers have determined exacting and scientific ways to brew teas, brewing equipment is available at garden centers or on the internet. Some garden centers are brewing in large batches so customers can conveniently draw-off what they need by the gallon!

There are many tea making methods, from the simplest home bucket method to technical and elaborate brewers with plenty of debate over different ways. Aerobic brewed teas have much higher microbe population densities than extracted teas and for this reason are the teas of choice. A good head of foam and scum on top signifies healthy microbe action! Try out different methods for yourself if you have the time and the gear, and love researching. Whichever you choose, your plants will benefit!

TEA MAKING TIPS

First of all, Temp and Timing matters, especially to the home gardener brewing outside, not using a brewing system. The microbes we want are the most happy at about 75 F, a comfy room temp for us too. Put your brew out of direct sunlight.

Based on Marc Remillards book “Compost Tea Making” temps/time are: 24 hrs @ 75, 36 hrs @70, 42 hrs @ 65 and 48 hrs @ 60. 95 and higher is a no go, just too hot! Your microbes go anaerobic. If you are using a brewing system, you can use an aquarium heater to ensure a constant brew temp especially if ambient is cooler at night. So it helps if night temps are 60 up.

Choose a clean 5 Gallon container or a size that suits your needs

The right water! Rain water is best or let it sit out overnight to allow chemicals to dissipate, or bubble water through an aerator for a minimum of 20 minutes. The chlorine will be released as a gas. Or, add a small amount of powdered ascorbic acid (vitamin C) or humic acids. If you start with chlorinated water it will kill some of your microbes before you get started.

Compost Tea Bucket Straining Painter's Mesh BagStraining your Tea! There’s various thinking on how to strain your tea.

The easiest and simplest is to use a sock, cheesecloth bag, but let the sock be big enough to allow the ingredients you put in it room to move around as it is swished through the water. Clearly those will not accommodate a third of a 5 gallon bucket’s worth of compost plus whatever else you put in. If you will be foliar spraying your tea, sock or pillowcase fibers are too tight to allow the good fungi and nematodes to flow through.

So! Super easy but has a small price, is a painter’s bag, 400 microns, 5 gallon size (they come in different sizes). Perfect! You put it in the container you will use, the elastic top fits over the top of the bucket. When the tea is done you simply lift it out. It has a durable nylon mesh and can be used several times. Add your leftover solids to your compost pile or as a soil topper mulch. Rinse out and dry your bag ASAP.

Or if you already started your brew, just get a 400 micron mesh strainer that fits your bucket, put it over a second bucket, and pour your mix through.

INGREDIENTS! Microbial diversity!

Add Compost

CAUTIONS Unfinished compost or uncomposted manures may contain harmful pathogens and compost that is too old may be nutritionally deficient. COMPOST TEA and MANURE TEA ARE NOT THE SAME THING! Manure teas may be made the same way but are not generally recommended as foliar sprays for veggies and are not as nutritionally well-balanced.

Use well-aged, finished compost The best is good smelling, very dark, broken-down into minute particles like course cornmeal. Dig deep down inside your bin, near the bottom. This is where organic material will be most decomposed and fresh, teeming with life. All you need is a good shovelful or two, maybe a third of the bucket, for a 5-gallon bucket of compost tea.

Add Manure

Cow manure is better than steer manure if you can get it. Chicken manure is good. Less of it does more. Be careful of free horse manure. It can be salty, and if the horses ate pesticide sprayed hay, or the stalls have been sprayed to repel flies, you’ve got toxins. All manures need to be very well composted, except bunny poo, which you can sometimes get free at shelters. Bird guanos do different things. See more soil tips and about quanos. 1 cup of manure may be quite enough. Most importantly, DO NOT foliar feed leaves you will eat, like lettuce, with animal poo brews!

Add Worm Castings! 

In nature, worms are a natural part of soil. In addition to soil nutrients, it’s smart to add worm castings. They speed germination of your seeds, seedlings grow faster. Worm castings help your plant’s immune system, and you have measurably more produce! Plants like strawberries, that tend to attract fungal spores will also benefit. Castings contain anti-fungal chemicals that help kill the spores of black spot and powdery mildew! Growing your own worms and harvesting vibrant fresh castings is ideal, but if you don’t have time, simply buy the best organic castings you can get, fresh and local if possible! More about growing worms! Add 2 cups to your 5 gal bucket.

Compost Tea Seaweed & Herbs - Borage Nettle Comfrey Brew

Seaweed and herbs – Nettles, Comfrey and Borage Tea at Milkwood Permaculture Blog

You can add all kinds of supplements at the same time! Put compost, manure/fish emulsion, worm castings, pond muck, powdered seaweed – 2 tablespoons kelp powder, 2-3 crushed Aspirin, rock dust, alfalfa pellets, chopped nutritious comfrey/borage/tansy leaves all in a bucket together – adding one volume of compost to 4-10 volumes of water. Let them sit overnight, a couple of days, stir a couple times, when you think of it. This turns the tea into a balanced organic fertilizer.

Compost Tea Bottle ComfreyComfrey, a dynamic accumulator, is especially nutritious! Having as much as a 20-30 feet deep root system, it bring minerals and trace nutrients up into its leaves that are unavailable to other plants. It is also the only plant that contains a form of vitamin B12. Mash it in a mortar & pestle, or use a big stone to break it down. That makes it easier to stuff into a stocking or 400 micron mesh bag, and speeds decomposition. Put comfrey in loosely, not too firmly, so the water can circulate around it. Even add a bit of healthy soil! You can make just a comfrey tea alone if that suits your needs. More about comfrey at Nantahala Farm & Garden

How long does it take? Add Sugar or Molasses! Aeration!

It has been shown that adding a simple aquarium pump to the bucket and letting it run to percolate the mixture will increase the potency of the finished mixture, and can be completed in as little as 12 hours to 2 days. If you want a super concentrate, let it brew a week, or more!

Recent research indicates that using some kind of aeration and adding a sugar source (unsulphured molasses works well) results in an excellent product that extracts the maximum number of beneficial organisms. 2 Tablespoons of unsulphured Molasses is good. An aerobic environment favors the aerobic microbes, physically pulls them off the compost and supplies air they need to multiply. This aeration is crucial to the formation of beneficial bacteria and the required fermentation process. It increases the absorption of the water and organisms. For the bucket-brewing method, you must stir the tea a few times during those hours or days it is brewing to aerate it. If you go over the time needed, you need to add more food for the microbes (sugar/molasses), and probably a little more compost.

Caution! Commenter Suburban Hobby Farmer on a compost tea post says: I’ve also read a study from a university extension service that says you shouldn’t use compost tea on indoor seedlings –especially if it has molasses —  because of increased damping off. According to the study, this is true even when watering from the bottom. A 2004 study says a more successful brew intended for seedlings has sufficient aeration, cuts back on the molasses, uses humic acid and kelp additives.

Anaerobic? You waited too long and your tea has gone anaerobic? Your tea should always have an “earthy” odor. If it smells bad, throw away the tea and don’t put it on your garden soil or compost pile.

Wash Your Gear Immediately! Bio-slimes build up inside your brewer or in your 5 gallon bucket. In a brewer this means walls, tubes, small crevices at the bottom. The pressure of hose water isn’t enough to remove it. It may take elbow grease, 3% hydrogen peroxide or a solution of 5% baking soda.

Here I’ve added a few notes to Shelle’s Quickie Recipe and instructions:

  1. 2 cups worm castings [or your choice of ingredients]
  2. 2 tablespoons corn syrup or unsulphured molasses. Molasses feeds the bacterial growth in the brew and also contributes trace elements of iron, manganese, copper and potassium.
  3. 5 gallon bucket
  4. Old pantyhose (no holes), a bag if you are doing soil drenching. Manure tea not recommended for foliar application.
  5. Water (rainwater is best or let it sit out overnight to allow chemicals to dissipate)
  • Put the castings (etc) in the sock and tie it closed
  • Submerge the stocking in water
  • Add the corn syrup and soak for 24 hours, stirring every few hours. Your mix should never be stinky. Like good compost, it should smell earthy.
  • Dilute to a 3 to 1 ratio, use within 48 hours

How long will my tea last? It is best to apply your compost tea immediately; however, it can still produce benefits if applied within 4-6 hours of removing the oxygen source if you are aerating. Remember we are talking about living organisms, trying to keep them in optimum health!

Applying your finished tea!

Diluting your tea. You can use your compost tea full strength on plants that are sickly or not growing well. Otherwise, it usually works well to dilute your tea half and half with de-chlorinated water (you can dechlorinate your water by letting it sit in an open container for a day). Another way of diluting it is until it looks like a slightly dark iced tea for soil/root drenching, weak iced tea for foliar feeding. Of course some teas are stronger than others depending on what’s in it and how much water is used. Work with it to find what works for you.

Will you use it as a soil drench or a foliar application? BOTH!

If using it as a soil drench, dilute or apply it full strength. If your tea is good, you really can’t overdo it! And you don’t need to strain it. But for young, delicate or houseplants try it diluted first. Amazingly, only 5 gallons of compost tea can be diluted to cover approximately one acre of land, and still produce benefits!

Tea to be used as a foliar application you must strain. Use a 400 micrometer mesh or screen. The mesh is big enough to allow the fungi and nematodes to flow through it, while trapping larger particulate matter that will eventually clog your sprayer.

Make sure that the sprayer you are using is designed for compost tea. Many sprayers apply with too much pressure, kill the microbes before they even make it to the plant surface. You need 70 pounds psi or less. Use a smooth, slightly-curved nozzle. With 90 degree bends in the nozzle, the microbes can be damaged. Try to arc or parachute, your application onto the leaves so the microbes land more gently, not head on.

Foliar Feeding - Rose Upturned to Moisten Undersides of LeavesApply with a watering can or a simple garden sprayer. Soak the soil to the dripline. When foliar feeding, be sure to add 1/8 to 1/2 tsp vegetable oil or mild dish-washing liquid per gallon to help it adhere to leaves. Use a watering can with a head that rotates so you can spray both on and under leaves. Minerals and nutrients are absorbed through the leaves and the roots – the WHOLE plant! Apply early in the day, avoid applying in direct sunlight. Ultraviolet (UV) rays kill microbes. If you must apply during sunlight time, do it before 10 am or after 3 pm, when UV rays are weakest.

If you do soil drenching, once you apply it, keep it moist for a few days to a week so the microorganisms have time to settle in, strengthen and multiply! Space out your applications a bit to give them time to get results. If you need a little more mojo deeper in your soil, down where the roots are, use your spade fork, the kind with the short wide tines that are spaced about two inches apart. Push your fork all the way into the soil, wiggle it back and forth to make holes, lift it straight up back out. Pour in your tea. Close the holes. Water a bit the next few days so your soil stays moist below and the organisms can thrive. Your plants will thrive as the root zone is so kindly treated!

When, How often?

Why wait until your plants are in the ground to add teas?! Start feeding your soil soonest! If you have your plant placements in mind, be sure to invest your teas out to the anticipated dripline so feeder roots will get some.

Make your tea applications every two weeks until your plants start to bud. We want our plants to make fruit, not foliage then! Some suggest to apply your tea at least four times per year, 1x spring, 2x summer, 1x fall. If you are trying to overcome disease, you may need to apply compost tea every five to seven days. If your soils have ever been sprayed with pesticides or otherwise compromised, apply more often.

Teas are perfect for container gardens, right?! You can buy ready made tea bags. You can buy Tea! No digging, just feeding.

Some tea making techniques are purposely biased toward bacterial, fungal or neutral predominance. It is speculated that one day we can selectively make teas focused to prevent/heal certain plant diseases or upset pest cycles, preventing infestations, and we are already making super teas to inoculate specific crops for super health and production. Eric in Denver says: ‘Now is our chance to get in on the ground floor of this exciting new science. Get a microscope (400x), learn to identify the main types of soil organisms, refine your brewing techniques, and set aside a place in your garden for experiments. It sounds much harder than it actually is, and there is plenty of work to be done.’

As of early 2011, there was very little evidence that proved the benefits of aerated compost teas; non-aerated teas seemed to fare a little better. That’s similar results as whether to turn compost or not. Turned compost processes faster, but unturned compost is higher in nitrogen! In the Journal of Plant Pathology 2015, Effect of Aerated Compost Tea on the Growth Promotion of Lettuce, Soybean, and Sweet Corn in Organic Cultivation, four types of compost were brewed and then the available nitrogen was determined, as well as the density of microbial communities, along with their effect on plant growth characteristics. Across the board it was shown that aerating compost tea released more nutrients, increased microbial counts, and helped plants grow!

Some practical points: When your tea hits the dirt, the water near the surface remains aerobic sustaining the aerobic species in the tea, and the water that soaks deeper becomes anaerobic sustaining those species. In other words, the soil microbe stratification remains the same as nature makes it. If you apply tea to your soil, made with the same compost you grow with, you are making extra work for yourself! But if you add biodiverse amendments to your tea, it supplies an array of tasty ingredients your compost likely doesn’t have. Compost supplies the organic matter that tea doesn’t supply, so it is critical in and of itself, plus it has many times more nutrients than a diluted tea. But teas are great for potted plants and lawns! And if you foliar feed your veggie plants, the uptake is greater and works within an hour!!! So think through why and how you will use teas and make them accordingly!

Here’s to a blessed summer of happy plants and abundant harvests!

Poly Floating Row Cover - slits for daytime ventilation. GreenHouseWorld.com

Have you ever used these?  Why not?!  Your family never did?  The cost factor?  They sound great!  They’re not just for big farmers, you can get them from nurseries and most seed catalogs!  I’m going to give them a try this year.

USES  Use for warming your plants both for starting spring crops early, and to ripen finishing fall fruits.  Use for frost protection, spring and fall.  Keep away harmful insects that eat or lay eggs, spread viruses.  Keep out birds and bunnies.  A caution:  ‘Colorado State University entomologists have found that overwintering insects can be trapped under the covers next to their favorite plants and be ready for action in spring. Some of these insects are tomato hornworm, onion and other root maggots, flea beetles and the [Colorado] potato beetle. Cultivate the soil before planting to reduce the number of surviving insects. Better yet, rotate crops so the survivors do not find their favorite plants nearby.’  OK?

How they work!  If for heat and growth, lay down black plastic mulch for soil warming and weed prevention. Make your slits in the plastic, plant. Put on your row cover. You can put it over hoops, over tomato cages or wires like hardware cloth bent into an arc, tented, or laid right on your plants, installing enough so your plants have room to grow up underneath. Anchor it well so no marauders can walk under or slither in. You can water right through it. Cover a row, or cover your entire raised bed!  If you are using the garden cloth row covers for freeze or grasshopper prevention, don’t let the covers touch your plants.  Since they are good both to keep your plants warmer when planting early, and help with cool weather frosts and freezes, this is one time you can have it both ways!  🙂

They come in lots of varieties – ask questions, shop around.  Select for your needs.  Get a rig that’s easy to lift for tending, and harvesting, especially if you use them to protect your strawberries from birds.

Insect protection

  • The surest way to protect plants from hungry grasshoppers is to cover them with a barrier, such as a floating row cover or lightweight cloth. Be sure to hold the covers above plants with hoops or stakes, because grasshoppers are more likely to eat their way inside if leaves are pushing against the fabric.
  • Beets & Chard  Leafminers are the most common pest.  Cover plants with fine netting or cheesecloth or floating row cover to protect them from adult flies.
  • Effective in controlling cucumber beetles, squash borer and squash bugs.
  • Flea beetles on arugula, cucumber, eggplant, radish.

Double up under the covers!  Plant your main crop you want to protect, interplant with a smaller understory plant on the sunny side!  You might put in some eggplant with arugula and radish interplanted on their sunny side.

Remove and store when no longer needed!

Danger of frost is past
The insect’s cycle is over.  Know your insect.
You no longer need more warmth
To allow pollination.  Especially melons, cucumbers and squash, that depend on insects for pollination. 

Sustainable.  Pesticides need to be applied weekly and/or after every rain, but with row covers they can be avoided completely.  Keep your soil clean, and our ocean safe.  Not only that, they save the time it takes to apply any formulas you may concoct, and if you are careful, you can lovingly reuse your row covers!  You can use them several times a year, per weather need, as different plants need protection as insects cycle, and next year too!  This is the best kind of ‘dirty laundry!’
