This best-selling guide has been revised to include an expanded section on establishment, irrigation, pruning, and soil and nutritional requirements. Also new is a discussion of the mossy rose gall and an expanded reference section. Healthy Roses adapts Integrated Pest Management practices to the home garden—methods of controlling pests and diseases using beneficial insects, traps and barriers, and less toxic pesticides such as soaps, oils, and microbials. The book also covers careful selection of varieties, site selection and planting, proper watering, how and when to prune, and weed management.
