Spraying Peach/Nectarine Trees to Prevent Leaf Curl

On Friday, I sprayed my peach and nectarine trees to control peach leaf curl. I also sprayed them in late December. I have been spraying my peach tree twice each winter while the tree is dormant since I planted it back in 2002.

I have heard people coming into our local nursery complaining about peach leaf curl in the spring. Unfortunately, it is too late to spray then. The spray needs to be applied at least once while the tree is dormant. I typically spray twice. In very wet years, I spray three times.

Now is the time to spray peach and nectarine trees to control the leaf curl fungus. I have read that the most important time to spray is just as the buds are beginning to swell, and before the blossoms open up. With all of the warm weather we have been having in the past month (today the high temperate neared 70 degrees again), the buds on my white nectarine tree are staring to swell (see above picture). I expect it to bloom before the end of February.
