sour cherry with yellow leaves

My small sour cherry tree has yellowing on about 10% of the leaves. Is this a disease? If so, what should I do?

TIA for any help!

Can you post pictures please?

Also tell us more about your tree. For instance, when was it planted?

RE: sour cherry with yellow leaves

I have a terrible time trying to post photos.

My tress is about 8 years old. It has never had a really great crop. Two years I have been able to get one pie's worth of sour cherries from it. This year I think the birds got almost everything.

It's about 12 feet tall and otherwise healthy. Just some of the leaves (less than 10% probably) are yellowing and have some black spots on them. I would guess this is a fungus of some type?

Thanks for any advice. I will try to post a photo.

It sounds like cherry leaf spot. Hard to say without viewing a photo. Captan or Chlorothalonil can be sprayed to prevent further infection. A few leaves with spot are not a big problem this late in the season. If the issue is
severe, then it is a problem as heavy defoliation can weaken the tree.

Chlorothalonil cannot be sprayed after shuck-split when you have fruit on the tree. Now that this season's cherry
harvest is over, this product can again be used if needed for fungal control should conditions warrant.

Your location could help also.

Your tree might be failing to take up soil nutrients, because the soil pH is too high. Yellow leaves can be due to high soil pH, so it would be a good idea to get this tested, or do it yourself.
