My peach tree produces great but it had a black spotted fungus last yr. This yr I brought some fruit tree spray but haven't used it yet, cause they don't have blooms. |
There is a bacterial black spot disease that affects some peach trees some years, depending upon the spring rain fall so your tree may not develop this problem every year. However, since you have already purchased a spray for your tree, go ahead and use it - according to label directions. Best wishes with your peaches! |
