I came home from work tonight and went around to water my tomatoes and bean seeds, and guess what I found? The bean seeds had come up out the top of the soil...they were opening up, and I suppose the action of that worked them upward, until some of them were laying on top of the soil. I made new holes and dropped them back down again! LOL. It was good for a laugh...they are very entertaining seeds! Maybe this means they will be very vigorous climbers, and hopefully proliferative too! LOL.
