Q.Fruit Tree Leaf Curl
I planted one peach and one nectarine tree two years ago. Last year both trees had leaf curl blisters on the leaves. Last November I sprayed the trees with bordeaux mixture but again this year the trees are just starting to show leaves and flower. They are showing signs of leaf curl. Is it too late or is there anything I can do to stop this problem?

The only treatment is to minimize stress by supplying additional fertilizer and irrigation as well as removing some of the fruit load. Applying a fungicide in autumn will help prevent future problems. You can also try spraying some in spring prior to bud swelling. While it is often deemed to be less effective than fixed copper products, lime sulphur is an acceptable form of organic control for this disease.
