Recommended Spray Programs, by Rosemania

Information on when and what to spray:
Fungicides - With any good spray program, the key is "Prevention". You don't want to be spending all your time fighting blackspot and powdery mildew. You want to prevent it from happening in the first place.
Insecticides & Miticides - We do not recommend spraying insecticides or miticides preventively. Spray them only when you have a pest problem.
