My dwarf peach tree's leaves are curling and have a kind of sticky substance on them. The tree is loaded with peaches, so how can I treat the leaf curl situation?
Leaf Curl on Peach Tree
Certified GKH Gardening Expert
Peach tree leaf curl is a common fungal disease among these fruit trees. Prevention is the best form of attack against the disease, however. Once your tree has developed leaf curl, it is difficult to save your peach harvest. Unfortunately, fungicide will not kill this disease. Prune off diseased portions of the tree and try to thin out the number of peaches you have on the tree. Also clean up any debris that may have fallen. In late fall, you can treat with a fixed copper fungicide to try and prevent the re-occurrence of the disease.
