I live in east TN. I want to know what to use to prevent brown rot. It's the first of March- dormant oil until when? Buds are forming but not open. What about sulfur spray? When should it be used and how often? Same for fruit tree spray, when to start and how often? Can I use sulfur spray and fruit tree spray during the same time span? For instance, one spray one day then two days later the other? THANK YOU! No fruit for two years! Also, I have apple trees.

The fruit spray and the sulfur spray should treat for the same thing so you only need to use one or the other.
Start spraying now and spray every 2-3 weeks until the blossoms fade. Then spray again when the peaches start to ripen.
