I have to add a little note about those dead leaves. After they turn brown or yellow, you don't have to remove them from the ground between the roses, but please do remove them when they land in the crook between canes and branches. Whenever I find a little branch that has died back, I invariably see a leaf caught in the crook where the node branched out. It's hard to believe that roses can have such a highly toxic effect on themselves, but they do.
