As winter’s knocking on our doors, we’re decorating for Fall and Christmas, putting up the last of our canned goods, and putting our gardens to bed. However, Winter doesn’t have to be a time of complete rest for your garden. If you find yourself needing to improve the quality of your soil, or prevent water run-off and erosion, planting a winter cover-crop can give you a head start without having to babysit it in the cold.

Why Plant a Winter Cover Crop

  • Prevents erosion. The root structure of cover crops will knit the soil together to prevent the melting snows or cold winter downpours from washing your fertile soil away.
  • The top growth will be tilled under in the Spring, providing excellent compost and plant fiber
  • Suppresses weed growth
  • Return nutrients to the soil. Many cover crops release sugars, and microbes to the soil (often as far as 6 feet down!) that will feed next year’s crop.

Cover-Crop Options

  1. annual ryegrass
  2. winter rye
  3. winter wheat
  4. oats
  5. white clover
  6. sweet clover
  7. crimson clover
  8. hairy vetch
  9. buckwheat
  10. field peas

An added bonus is that many of these plants are also edible for humans and livestock or can even be harvested for their medicinal properties. Grow some winter wheat and after it’s finished it’s first job of protecting your garden bed, it can be given a second one in your pantry!

Grow some field peas and harvest them for your chickens, or some white clover and dry it for a medicinal clover tea afterwards. For more information on how to use clover medicinally, check out Herbal Academy’s blog post.

When to Plant

If you have fields that will remain fallow for the growing season, clovers, fescue, buckwheat are good choices, as they’ll grow all summer, but be killed off by the frost.

For covering your soil later in the year, barley, ryegrass, oats and winter wheat are your only options, as they’ll withstand the frost.

Before tilling your cover-crop into the soil, mow it down and let it decompose for a few weeks, as decomposition within the soil can tie up nitrogen. An added bonus of doing this, is that the cut clippings will still act as a mulch and help your soil retain water and prevent runoff.

Now it’s your turn! Have you ever used a cover crop? If not, why not?

  1. My mom has been canning pear preserves for the last couple of weeks. She lives in a different state and I sure do miss her and her large garden. I keep saying I’m going to plant a garden next year, so I need all the tips I can get.

  2. We cover crop with clover and it has worked wonders for our soil. We also cover crop, believe it or not, with mushrooms. To build soil for a year or two in new beds, we spread a layer of wood chips and inoculate with wine cap mushrooms. It’s worked wonders with our clay soil.
