I'm spraying my plants today and I noticed rust spots on my hollyhocks (even though I've been spraying regularly) and some spots on my cannas. I have 3 questions: 1. What are the spots on the cannas? 2. How many spots warrant removing a hollyhock leaf - percentage wise I guess? 3. Can anyone recommend a sprayer that has an adjustable nozzle that will spray upwards so that I can better reach the backs of leaves? As always, bless you and thank you for your help. Terri.
