Newbie peach spray question
I am growing peaches the first time and I am confused about the spraying for leaf curl thing. The trees I have are "resistant" according to the Dave Wilson tags on them. They look like they will break bud within days and I want to know, do I need to spray?
I understand they need it three times, the nursery they came from is very well known for its great fruit tree culture so I am sure they sprayed earlier if needed. But being Saturday, nobody there is picking up the phone! (It's a small family business).
Gardenwebbers, can you help a girl out? Thanks!
