Bought two Beg. Rex-all chartreuse green and the other pinkish-cannot rememeber names. Anyway,they stayed beautiful for 3 months or so, then all the leave dropped off, now all I have left are the tubers. Are they still alive, do I toss or do I leave until spring. This is Miami, FL and all things grow all the while, I think. Also, snails got to some of the leaves. They had holes, but would this cause all the leave to fall from the base of the stems?
