Great idea.
Skip the tug-of-war when the zinnias, marigolds and beans are done this fall. Take the pruners, cut each plant off at the soil, and let the roots stay where they are.
Ohio State University Extension's master gardeners say to cut annuals at the soil surface, leaving the roots in the soil to add organic matter. The UC Master Gardeners of Contra Costa County explain what happens next: worms, bacteria, fungi and other soil life slowly break the old roots down underground, and the decaying roots leave the soil more porous, with better air and better water holding.
Pull the plant and all of that comes out on the end of it, clump and all. 🍂
