When I first bought seeds for green beans this past winter I thought I would be watching the plants grow six feet tall or something...when my plants only got to be about 1 1/2' tall I guess I realized that they were a bush bean of some sort apparently.

My question is this...I have 4 squares of beans...8 plants per square, and have got many beans off the plants so far, but they seem to have stopped flowering. Should I rip them all out, put in some new compost and start over with seeds or plant seeds now, next to the existing plants and when my existing plants are completely spent cut them at the soil line?
