I cut mine back after they have yellowed also. Once they have yellowed or withered they aren't of use to the plant. When the tips die back I just trim to the healthy looking green area. As for weeds---- I don't like to use chemicals so have been wondering about the pre-emergence that is made from corn. Has anyone tried it? If so does it work?
