White fur on apple trees

QuestionsWhite fur on apple trees
Anita Kennedy Staff asked 14 years ago

We are not sure what type of apple trees we are growing but they are young, they are at a max. of 12″. There is white fur growing on the leaves, it is not on the bark as suggested in so many other people’s blog. Is this a fungus, should I be worried. It doesn’t seem to be doing any harm I just don’t know what it is?
