I'm hoping someone can give me some insight on why my apple tree is dying or already dead.
I have a group of 7 interstem apples planted by the entry to my house. I planted them out last spring and one, a Kerr Crab apple on M111/Bud9 died after growing relatively well all summer. I had some other grafted apples in my nursery area, so I pulled the dead Kerr and planted a Chestnut crabapple on M111/M27 last fall after dormancy and it woke up and grew relatively well this spring, but now it too appears to be about dead.
The nearest apple is about 2 feet away (same rootstock/variety) I think it is fine, although not growing as vigorously as I'd like which I'm chalking up to the rootstock. So my questions is could there be a problem now in that spot (replant disease) or is it just random bad luck from fireblight or something else?
I'd really prefer to keep an apple in this spot and have a Kerr or a Monark on G696 I can try in that spot this Fall, but wondering if I should go to one of the pears I have on OHxF87 instead. Thoughts?
Here are some a picture of the full tree and a closeup of the foliage. It appears almost as if it is drying out from the bottom up, so I expect it is a root issue, but why in this location and 2 times when the other 6 so close by are fine?
The mulch was added about 3 weeks ago and is away form the trunk although maybe a little has washed down from watering.
