Whats wrong with my apple trees?
Starting in mid July the leaves on the HoneyCrisp - about 5 years since planting and multiple trees - appear waxy, following by curling and then yellowing of the curled portion. This has occurred for several consecutive years. The trees will bear one or two apples that are misshaped. I do not find aphids and I spray the trees for apple scab on a regular bases. The above symptoms do not appear on the Haralson, honey gold or chestnut crab trees. The sprays used: Captan,(Home Orchard Spray) Sevin, and myclobutanil. I do not use a sticker with the spray.
It may be that your tree has honeycrisp chlorosis. Oddly, this disorder seems to only affect honeycrisp trees:
