I'm new to gardening. I have two container gardens with annuals, including snapdragons. I recently discovered an budworm infestation and treated with BT this past weekend. I now have lots of stems with raggedy leaves, many buds with holes but only two or three blooms. My question is whether to cut away the damaged areas of the plant to encourage new growth, and if so - should I pinch off the damaged buds one by one? Cut off an entire stem with buds? Or cut back the budless stems with leaves only? Or leave alone let nature take its course?
