My early pink lady apple tree and honeycrisp apple trees are infested with aphids or some type of leaf fungus. Can you help determine what the likely issues are and hoe to treat them? I have 6 total semi dwarf apple trees all planted together. Two are liberties that seem fine, one fugi that might have some aphids, one pink lady that is really bad and two honeycrisp that seem to be starting to get aphids and what ever leaf fungus the pink lady has.
