Issue with apple tree #878705

Asked July 25, 2024, 10:45 AM EDT

Some leaves are turning brown and some apples are curdling. I got this tree this spring from burgess. Any idea what is the problem.

Hi Brent,

I can't be sure but this looks like fireblight or black rot, both serious diseases of apples.
