It is a generally accepted fact that once soil temperatures drop below 45°F (7°C), biological activity slows to a crawl, and the soil and all its life forms hibernate through winter. By this logic, soil cannot be expected to change for the better during the winter months, and yet it does when given a little help. Here are five ways to use the winter season to improve the soil in your organic garden.
1. Wait to cultivate.
One of the reasons why soil feels so loose and friable toward season’s end is that it is impregnated with the summer’s “crop” of fungal hyphae and mycelium – microscropic threads that will slowly rot through winter, along with roots left behind by vegetables and weeds. As far as nature is concerned, the table is set, and you would most definitely crash the party if you dug and turned the bed. So, unless you have a good reason for doing so, for example you want to prepare space now for an early spring salad garden, in autumn it is better to mulch over vacant beds without cultivating them first. However, you have my permission to disturb soil as needed to dig out nasty perennial weeds.

3. Grow winter green manures.
Fortunately, many cold-hardy plants that make great winter green manures did not get the memo that they were not supposed to grow in winter. Winter grains in particular are specialists at protecting the soil from erosion through winter, all the while developing huge root systems that increase soil organic matter content. When cut back to the ground in spring, hardy legume winter green manures like hairy vetch or winter peas leave behind nodules of nitrogen, ready for use by the next crop.

5. Compost under cover.
Garden beds that will sit vacant until spring can be heaped up with compost (without cultivating them first), and then covered with an old blanket or even a low row cover tunnel. In this way, the bed benefits from a deep layer of compost at the surface, which is further enhanced by a cloth cover. ……….
