I thought about that, but decided against it because I wanted the soil to have as much "free soil" as possible. I know a few roots here and there won't cause a problem. However, I did that with my lettuce because I thought they had all died, and they came back just from the roots. I had not planted anymore seeds and had actually given up on lettuce.
Have you thought about leaving the roots in the soil from the previous year's vegies? Wouldn't they decompose and feed the new vegetables?
