The trees are over 10 years old and their fruit has shown these symptoms for the past several years. The owner said he sprayed the trees with insecticide every 10 days after 3/4 petal drop. Is this Cork spot, water core or something else? http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13973 http://www.uwex.edu/ces/ag/plantdoc/viewCase.cfm?cid=13973 Thu, 17 Sep 2009 04:09:49 CST Hazen variety apple tree has leaves curling on upper 25% of tree. Trees was planted in the fall about 2.5 years ago in the fall and were about 5 ft tall. Soil is 80% clay/20% sandy soil and receives full sun. Tree is watered regularly. Applied Scott's weed-n-feed on lawn but very little around trees. Other apple trees are unaffected. Any idea what is causing leaves to curl?
