Rose Powdery Mildew: Oil Sprays, Don't Over-Prune

Florida panhandle roses with mildew on new growth/buds: cutting all new growth prevents blooms. Use oil sprays (neem, horticultural) mixed with soap/water—cheap, effective.

Advice

Old garden roses need less spray; modern roses need more.
Oil + detergent sprays go far, cost little.
Stop cutting new growth; you need it for flowers.

Consistent spraying, not pruning, controls mildew.
