Need a Sherlock Holmes of apple disease (or ?)
Hello, fellow fruit growing fiends:
I have a mystery that has stumped many apple disease experts -- are you the detective that can crack this case?
My apple trees get puckered leaves and pale yellow spots areas. Some of the leaves turn yellow with green veins, which I understand could be a sign of iron chlorosis. Later in the season the leaves get brown spots. I sent the leaves to a local apple disease expert and she said she could not find any signs of fungal spores. The trees also have not bloomed, although they are 6 or 7 years old and have lots of fruit spurs. Local soils tend to be acidic, although my home test kit was inconclusive.
Thanks in advance for reading and for any suggestions. :)
