Zone 4 cover crop for raised beds?
Hello! I have been gardening in 4 beds (4x4 wooden sides) the past 2 years. I compost and add this to the beds, working in a bit by hand but no tiller. I add fall leaves to cover over the winter. I use some fish emulsion, epsom salt, and crushed egg shells in garden. Mulch garden with saved fall leaves. This year I have some bacterial speck on some of the green tomato fruit. I read that cover crops could perhaps reduce the risk of disease. Wondering what might be recommended - would not be able to "mow" in spring with the wooden sides of the beds.
