If your yard attracts children and pets, you may need to reconsider how, when and if you use certain products. If your roses are located near a pond, birdfeeders, or among perennials, you may need to be more conscious of product toxicity to fish, birds and bees. Know your environment and read the label. First, grow healthy roses. The healthy bushes that grow in that soil develop stronger cell membranes, as well as natural pest defenses, that can withstand attack from pests.
Water is especially important.
When a plant is drought-stressed, it closes down its respiratory system. Next, reduce pest populations. Clean up garden litter than can hide eggs and pupae. Locate your rose beds away from wildflower or weedy areas, but not so far away that beneficials with limited range can t get to you. Keep your perennial beds tidy, especially over winter.
