You've got a pretty good looking garden, what kind of fruit trees do you have planted?
We've got a nice apple tree that's gotten a lot bigger over the last couple of years. We couldn't figure out why it wouldn't produce apples, just figured out recently we'll have to get a 2nd to actually act as a pollinator.
I have Grapefruit, 2 Orange, Papaya, Guava, 2 Lemon, Avocado and Loquat (although this one requires the least help ha).
Apple trees are super hard to get to grow fruit. I really wish that I could manage to grow one but they always died young. You're halfway there though! (And ahead of me too!) I wish I could offer some advice but I just kinda free-ball planting haha.
