Composting in Winter

Composting in Winter

Few things are sadder to a gardener than perfectly good food scraps not getting turned into compost. Once winter hits here, the ground is frozen solid. The compost pile gets frozen too. I’ve tried throwing the scraps onto the compost pile, but that seemed to invite every raccoon in town to come to dine in my compost bin.

How to make a compost trench

My best idea for composting in winter is to make a trench compost. This requires a little work in the Fall but produces amazing results. In fall, I dig a long trench right in the garden….about a foot deep and a foot wide. I leave the soil heaped right next to the trench with a rake nearby. All winter long, when I have a little bucket of food scraps, I dump them in the trench and rake the heaped soil over the scraps. Snow comes and goes but I can usually get to the trench.

 

What’s amazing about this process is that it attracts all the worms to the trench. Some composting takes place in the Fall, but most waits till early Spring. By early May, the trench is significantly decomposed and filled with hungry worms. By the end of May, when it’s time to plant tomatoes, the compost is broken down enough that I can dig big tomato holes right into the trench. Tomatoes are hungry plants that thrive on growing right in compost. This saves me the trouble of hauling compost over to fertilize the tomatoes. If it was an especially cold winter and the compost isn’t finished, I just plant right next to the trench.

Some people like to compost in trenches all year round. They set up a three-year rotating system where they compost one year, plant the next, and use the area as a walkway the third year. Pretty clever.

Another way to save time and labor in the garden.
