???'s about spraying with copper sulfate #241282
Asked May 03, 2015, 11:31 AM EDT
Recently I got an answer to question 220832 about trouble with a walnut tree not producing good nuts. The answer was to spray with copper sulfate, which we did. My present question is after mixing the CS spray I added a little seven spray and a small portion of dormant spray. I sprayed the walnut, apple, peach and cherry trees. Everything was fine except the peach trees have lost most of their leaves.
Did I do wrong by mixing the chemicals together? Do you think the peach tress will still produce the fruit that is already on them?

All those chemicals are labeled for peach trees. However, copper sulfate should be sprayed in the winter and early spring before the leaves are out. If the blooms fell off or no buds develop, you may just not have peaches or not many peaches this year. If the blooms and/or buds are okay, then you will probably have peaches. There may not be as many or they may not be as big because the leaves have fallen off the trees and the developing peaches won't have that source of energy that the leaves collect.
