It killed me to do it but had to remove 1/3 or so off my sir prize fruit today. It was falling over even with 3 stakes on it. I tied up the branches with fruit on them to lessen the load on the rest of the tree. Its the only tree that did hardly any self thinning.
That's tough but you do what you have to do. While staking a branch laden with 4 fruit yesterday I found 3 more on it! Pulled one. Of the 4 grafts I did, only the Sir Prize is holding 6 fruit and the Holiday is holding one. All fruit on the Ardith and Pinkerton dropped on their own.
What I don't understand is the massive drop on my Reed. I once had about 100. Probably have only 15 left now. BIG disappointment.
Spaugh, I recommend you thin your tree after fruit set like the peach growers do around here. They remove at least 40% of the fruit at pea size. Of course that is mainly for marketing and sales. Makes for bigger, colorful fruit.
