I've been dealing with Cane Borers -- have used glue and insecticide sprayed on the freshly cut cane, which has been working. Have noticed that my Double Delight and Luminesce are much more susceptible to the nasty critters, I think because their stems are wider where the bloom is attached. Roses with smaller stems don't seem to get "bored." Anyone else notice this? If you have been successful with other treatments let me know. Thx, cj
