Winter Green Manure • Woolly Pod Vetch, Oats, Peas and Mustard. Try as we did, we concede that it is just too cold out here to run the market garden during winter. With heavy frosts, overnight temps that get below zero and days that just never warm up or dry out, it’s simply not viable for us. So instead of feeding humans, we feed the ecology, the bacteria in the soil that will in turn provide nutrient-dense food for our local community come spring. A process of chop - drop - fork - tarp is employed to build organic matter in the soil and provide all those beneficial little microbes with tasty sugars and carbohydrates to eat. These rows will stayed covered until early spring when (hopefully) the green manure will be completely composted down and ready for planting out our greens, spring onions and of course, tomatoes.
