Last year we had a HUGE crop on our tree. The birds and squirrels got lots and I pinched about 50% (the tree was covered like crazy) yet I was still able to manage to harvest about a dozen! One dozen peaches out of hundreds of baby peaches. :). I was OK with that - I made jam with them, which is what I want them for. I thought the jam was too thick, but it actually spreads nicely and is bright in flavor. Five little jars of the most hard fought for jam in the history of peach jam!
Maybe our tree will be OK next year - I think our temps didn’t get low enough, often enough this winter. As our tree is very near the house it is in a micro climate - and that bit us in the butt this year.
I’m thinking that we need to do something to protect the crop next year, but the trees are now too tall to cover with bird netting, still the low hanging stuff should be able to come up with something.
I am thinking that hanging some aluminum foil, old computer disks, and/or pie pans might scare them off.
We have so many nut trees, that is what keeps them coming in I think.
You might consider planting some catnip mint under, or out by the drip line of the peach tree.
Catnip will encourage any feral cats or neighborhood cats to come visit which will reduce your bird and squirrel threat, and might dissuade any woodchucks from visiting.
Consider the catnip as a 'trap crop', unless you like catnip (relaxing) tea with camomile .
