Use Cover Crops to Improve Soil

By the esteemed Barbara Pleasant!

Cover Crop Pleasant Crimson Clover Batchelor's Buttons

Colorful companion cover crops such as bachelor’s buttons and crimson clover will not only improve soil, they’ll beautify your garden beds [and feed the bees].

Intro! Legume cover crops are more than pretty, they improve your veggie garden soil, a lot! There are informed choices to be made. Cover crops are in the same categories as Living Mulch and Green Manure.

I’m copying the beginning of Barbara’s wonderful post and will link you to the rest. She says…

There are three main ways to improve soil: grow cover crops, mulch the surface with biodegradable mulches, and/or dig in organic soil amendments (such as compost, grass clippings, rotted manure or wood chips). All have their advantages and none should be discounted, but cover cropping is the method least likely to be practiced in home gardens. There is a reason for this: Information on using cover crops is tailored to the needs of farmers who use tractors to make short work of mowing down or turning under cover crops. But when your main tools for taking down plants have wooden handles and you measure your space in feet rather than acres, you need a special set of cover crop plants, and special methods for using them.

How Cover Crops Help

A cover crop is any plant grown for the primary purpose of improving the soil. Since the early 1900s, farmers have used cover crops to restore fertility to worn-out land. In addition to helping bulk up soil with organic matter, cover crops prevent erosion, suppress weeds, and create and cycle soilborne nutrients using the power of the sun. Recent advances in soil biology have revealed two more ways cover crops can improve soil.

Rhizodeposition is a special advantage to working with cover crops. Many plants actually release sugars and other substances through their roots. They are like little solar engines, pumping energy down into the soil. With vigorous cover crop plants, this process goes on much more deeply than you would ever dig — 6 feet for oats and rye! If you are leaving your garden beds bare in winter, you are missing the chance to use cold-hardy crops such as cereal rye or oats to solar-charge your soil. Thanks to this release of sugars, the root tips of many plants host colonies of helpful microorganisms, and as the roots move deeper, the microbes follow.

But so much for scientific talk. If you’ve experimented with cover crops, perhaps you have dug up young fava beans or alfalfa seedlings to marvel at the nitrogen nodules on their roots, or watched a stand of buckwheat go from seed to bloom in four weeks flat. Or how about this one: It’s April and the soil is warming up and drying out. After loosening a clump of fall-sown wheat with a digging fork, you pull up a marvelous mop of fibrous roots and shake out the soil. What crumb! The soil’s structure is nothing short of amazing! These are the moments an organic gardener lives for.

Cover Crop Root Channels for New Plant Roots Bio-drillingBio-drilling is what happens when you use a cover crop’s natural talents to “drill” into compacted subsoil. For example, you might grow oilseed or daikon radishes as a cover crop where their spear-shaped roots will stab deep into tight subsoil. Bio-drilling action also takes place when deeply rooted cover crop plants penetrate subsoil and die. Then, the next crop grown may actually follow the rooting network mapped out by the cover crop. Maryland researchers were able to track this process using special camera equipment (a minirhizotron), which took pictures of the interactions between cover crop (canola) and crop plant (soybean) roots. As the canola’s deep roots decomposed, soybean roots followed the trails they blazed in the subsoil, hand in glove. In addition to reduced physical resistance, the soybean roots probably enjoyed better nutrition and the good company of legions of soil-dwelling microcritters, compliments of the cover crop.

Dozens of plants have special talents as cover crops, and if you live in an extremely hot, cold, wet or dry climate, you should check with your local farm store or state extension service for plant recommendations — especially if you want to use cover crops under high-stress conditions. Also be aware that many cover crop plants can become weedy, so they should almost always be taken down before they set seed.

How to Take Cover Crops Down

Speaking of taking down…  Continue reading!

From here, Barbara talks about how to take the cover crops down, then, which cover crop to use, what time of year to start it in which zone, the pros & cons of each, her experiences, research.

Or, you may not want to take down your cover crop. If you planted a short ground cover type legume, late in the season you may simply want to remove the larger plants, open up spots in the living mulch and put in winter plants! Your cover crop will keep on working as the older plants die naturally and feed your soil.

Two for one and save time and money! If you choose edibles as a cover crop under larger plants, you get living mulch and food! If you choose legumes, they are working at the same time you are growing your large edible plants! I do hope you consider this 100% natural organic method of restoring or improving your soil, improving space you won’t be using right away! You will have less disease, less pests, less amendment expenses. Plant with flower combinations like Crimson clover to make habitat for wild bees/pollinators, and beneficial predatory insects, for simple beauty!

  • Spring and Summer, cover crops also act as living mulch while feeding your soil. Toss seeds around and under bigger plants.
  • In SoCal and southern areas, Fall and Winter, use cover crops as green manure to restore and improve your soil for spring ~ summer planting.

The better your soil, the more handsome your harvests. To your health and happiness!

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.

Alyssum Garden Companion Flower Yellow Chard

Beautiful image and planting by Amy at Tenth Acre Farm, a suburban homestead in Cincinnati, Ohio!

Interplant and select wonderful companion plant combinations to make beauty, glorious scent, biodiversity, to protect and enhance your vegetable garden! Plant for bees and beneficial insects and edible flowers for yourself. There are so many magical choices and personal preferences. Design in advance, or simply add as you go. Intuitively try new groupings. Mix and mingle to your heart’s content!

Alyssum is a pretty little ground cover, living mulch!

Attracts beneficial predator insects like hover flies, ladybugs and lacewings that eat mites, white flies, scale insects mealy bugs and thrips! White Alyssum repels cabbage butterflies. As Alyssum spread, they are a lovely living mulch, beauty for free. Your garden is sweetly scented all Summer and alyssum brings butterflies and pollinators! It is a favorite old fashioned border plant as in the image above.

Flower Bees Bachelor's Button Companion Plant BlueTall Bachelor’s Buttons & Cosmos!

Big Beauty in Blue, Bachelor’s Button attracts pollinators, and like Alyssum, they also attract beneficial insects that will prey on damaging insects like scales and thrips. Since it and Cosmos are tall open plants, 4-5′, they can let filtered light through to plants that don’t thrive in direct blasting midsummer midday sun.

Comfrey for Compost and Healing!

Comfrey is a superlative choice! It is nutrient accumulator, has more protein in its leaf structure than any other known member of the vegetable kingdom! It has more than three times the potash of farmyard manure and with a similar phosphorous content, has much the same balance of plant foods as a chemical potato and tomato fertilizer, and one of the first discoveries on the Comfrey Blossoms Nutrient Accumulator, Compost ActivatorHDRA trial was that it behaved exactly like such a fertilizer! In trials, adding 1.5 pounds of wilted comfrey to every foot of potato row doubled the yield! Comfrey is invasive, so put it in a bottomless pot to keep it from spreading too much. It likes moisture, so by or near the spigot is a great place for it.

Besides feeding your compost, it is also a superb compost activator – grow it conveniently near your compost area. Throw in a few leaves each time you add a layer to your compost.

Not only is it good for your veggies, but has many amazing proven health benefits as well! Check it out online as Comfrey or Knitbone.

Herbs! Rosemary, Blue for Bees!

When in flower, Rosemary attracts bees like crazy and the bees will pollinate your beans, cucumbers, squash and tomatoes. Being so aromatic, the fragrance of the rosemary messes with the ability of ‘bad bugs’ to detect delicious vegetables! And, of course, Rosemary is a tasty cooking herb! Other herbs, like Lavender, will do much the same for you as Rosemary. If they are perennials put them in more permanent places, corners, entryways, and use them all year long! Also, enjoy your Rosemary as edible flowers sprinkled on your salad!

Borage Herb Blue Star Flower Pilgrim Terrace Community GardenSupport your bees! Bees can’t see the same spectrum of colors as we do. For example, yellow flowers appear blue to bees. And bees seem particularly attracted to blue flowers (and the yellow flowers that appear blue to them). That’s why our bees love Borage so much too! Help restore their population by planting plenty of Asters, Scabiosa, Blue Larkspur and all those yellows we love. Stagger your times of bloom to feed your bees all summer long! See more about how to have happy bees at Life on the Balcony! Walk in Beauty.
