Honey Crisp Apple Tree in the Pacific Northwest...

Our family has a question about our Honeycrisp Apple tree.  It's seen better days.    

Please see the attached pictures.

The tree itself has been in the ground for about 5 years (diameter of the trunk is about 3 1/2" at 3 feet from the ground).  For the last three years it continues to grow but the apples at this point look diseased.  We were able to salvage about 30% last year but this year they all look terrible.

We also have a Liberty Tree which is doing beautifully but are trying to get our friend the Honeycrisp to be healthier.  

Do you have any advice of what we could do?  I don't think the tree itself is dying because it continues to grow quite large (and the leaves look okay to me).

Thanks again for any advice you could provide.

looks like scab. it’s a fungal disease. there are probably things you can do about it, but a lot of the suggestions i’ve seen say that it’s best managed by planting resistant varieties...like liberty, for instance.

pruning for better airflow might help?

I’m guessing you live on 5he west side?  I’m guessing this from the amount of moss etc on the trunk of this tree.  Fruit trees like hot dry weather like in Wenatchee or Ellensburg with sun all day long. Good irrigation but lotsa heat and sun.  Is there a difference between the amount of moisture and sun that this tree gets from the other Apple?

If it’s scab I heard on the permaculture orchard YouTube channel you can spray 5:1 diluted whey on the leaves and fruit and it’ll take care of that.

Thank you everyone for your help.

This tree gets a little more shade than the Liberty but it sounds like it's scab.  Not wanting to give up on it yet, we are going to try that spray to product on it to bring it back to life.

Thanks again everyone for your responses.
