One eating apple tree, 4 years old, either Katy or Fiesta (I have one of each), had a great crop of red apples but they were sticky to touch and it was not easy to wash this off. What is it? (Other eater and the Bramley got scab this year.) Should anything be done now to prevent problems next year?
There are no sprays for sooty blotch, but apple scab sprays used in spring and early summer, do help.
