Fire blight on this apple tree?

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?

Check the stems for discoloration of the bark, while that doesn't seem to be a classic case of FB it very well could be the initial infestation.
Green or not, any bark discoloration is a sure sign that the tree is in trouble.

You can help the tree out with some minerals added at the drip line (I love sea-90 for that type of application, about half a cup should help a lot).
You can make a good aerated compost tea and spray the whole tree, top to bottom and the soil the tree calls home, this will go a long way to stopping FB in its tracks.

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.

A mushy interior can indicate root rot, check the trunk just below the grass line for evidence of rot setting in.

Really I think it is more a need of nutrients at this stage.

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.

Yes you are correct, the time to fertilize trees is in the early spring only. However, if you have built your soil with organic matter and your microbiome is thriving, you should not need to add fertilizer every year.
The only addition I make is to complete the mineral content of the soil, unless I have some disease issue which calls for a spraying of aerated compost tea.
