Am I correct in that I shouldn't fertilize until the next spring? Again, all of my reading has stated not to fertilize after the bloom, fall applications may cause growth that is damaged in winter.

No discoloration other than spots of lichen.
I cut down a couple of trees that we're mostly dead and only a few  branches of leading twigs. They had a soft/mushy core.

I read that mature trees dont really need any fertilizing so I havent put too much thought into that. I'll look into sea90.

Hi all. Moved into a house with lots of neglected apple trees. Before I go crazy, I wanted to confirm that this is fire blight. I don't see the shepherds crook so I am not 100% sure that it is FB. The twigs are still green on this section of the tree and I don't see any oozing anywhere. Maybe it's way past the oozing period since it's not blooming anymore?
