Cover cropping over bulb bed?
Has anyone tried planting a cover crop over top of a dedicated bulb bed? I was just reading an article about cover crops in Fine Gardening (December 2010) and the idea occurred to me. For example, a bed of lilies would come up in the spring and die back by fall so it seems like you could grow a cover crop over it through the winter and then mow it off in the spring before the lilies start coming up. With a dedicated bed of spring bulbs like Narcissus you could plant a warm season cover crop after the bulb foliage dies back in summer. Seems like this might be a good way to add organic material and nutients to the soil without disturbing the bulbs. Any thoughts?
