There is likely a huge mineral deficiency from 80 years of apple crops, so I would take a soil sample under each tree. I needed to add phosphorous, boron, potassium, zinc, copper. Tree cant make fruit without the necessary soil minerals. Soil testing is a very useful tool.

I unfortunately cannot afford soil testing there used to be cheep/free soil testing available in my state but I believe this has gone by the wayside (anyone who wants to prove me wrong please send links!!)
What I did do is spread 5 gallons of wood ash in concentric rings around the Tree One at 5, 10, an 20 foot distances from the trunk and then water them in. I have 5 more gallons of ash ready to go but I'm holding off (I really don't want to screw up)

Then either proceed with a work agreement with them, or hire someone less educated, or do nothing. Just don't prune them yourself.
