All About Cover Crops

Cover Crop
While we were on our vacation, Sunshine Through The Windows asked about when the right time to plant cover crops is. I thought I’d take the opportunity to make that small question into a post all about cover crops, if you don’t mind.

Cover crops (also known as green manure) are fantastic ways to enrich your soil. In fact they’ve helped to improve our soil dramatically over the years. Cover crops are a crop that you plant in the off season that works while you rest. Their roots help to break up hard soil and aerate it while also imparting nitrogen into your soil. You can see the nitrogen on our last years cover crop of favas and vetch here. In the spring you cut or mow down the crop leaving the roots in the soil. You can then gently till the soil to spread around the nitrogen and other nutrients the roots provide. As for the tops of the plants, they are a welcome addition to your compost pile that will help amend your soil also.

There are all sorts of cover crops that you can grow, favas, field peas, vetch, buckwheat etc. This year we went with a variety cover crop seed mix that our local nursery pointed us too. Normally, in our non snowy climate, it’s best to plant this in fall. However time escaped us this year and we didn’t get to it until December. If you live in a snowy area, you can plant this first thing in spring and mow it down in summer when your tomatoes and peppers are ready to plant out.

If you’d like to read more about cover crops and overall soil health, I can’t recommend the book Secrets to Great Soil (Storey’s Gardening Skills Illustrated) enough. We refer to this book over and over again.
