Frequently Asked Questions
What's the actual point of planting a cover crop instead of just leaving the bed bare?
Bare soil is vulnerable to erosion, nutrient loss, and weed pressure, while a cover crop holds the soil in place, suppresses weeds through competition, and in many cases adds organic matter or nitrogen back into the ground. Legumes like clover fix nitrogen from the air into the soil, while grasses like winter rye build organic matter and break up compaction with their root systems.
Do I need to till the cover crop into the soil, or is there another way to deal with it?
Tilling is one option, but many gardeners prefer to cut or mow the cover crop down and leave it on the surface as mulch, which avoids disturbing soil structure and the organisms living in it. Winter-killed cover crops, ones that die back naturally from cold temperatures, require no termination step at all and can simply be planted through in spring.
How do I know which cover crop to pick for my specific goal?
If nitrogen fixing is the priority, legumes like clover are usually the better choice, while grasses like winter rye or oats are stronger for building organic matter and suppressing weeds through sheer biomass. Blended mixes, like the seasonal soil builder options, are designed to combine several of these benefits at once if you'd rather not choose a single species.
