Hi, we planted a couple a Honey Crisp apple tree a couple of years ago. It has produced a couple of apples the last 2 years, but the apples got blotchy and fell off and the leaves have gotten blotchy. I've attached a picture of the apple and a picture of the leaves.

The photo is a little blurry, but from what we can see we believe the fruit has been affected by plum curculios and perhaps apple maggots.

These pests can be controlled with the methods recommended in the following bulletins.

We can't see the leaves well enough to comment on them Perhaps you tried to attached a second photo but it didn't appear. If so, please reply and attach a sharp photo of the leaves.

Hi, thanks for the response. I've also attached a picture of the leaves. I think this one may be a little blurry also.

We'd need to see more sharp leaf photos to be sure, but your tree may be affected by a physiological condition specific to Honeycrisp called leaf zonal chlorosis or Honeycrisp leaf complex. Mottling and curling are typical symptoms. The complex isn't caused by disease, insects or nutrient deficiency and usually doesn't affect the tree's growth or productivity
Compare your tree's leaves to photos and information at the following websites:
