Four falls years ago, I planted 2 peach trees side by side. The next spring, they both produced some peaches. The 2nd year, they were so full of peaches that I had to prune off a lot so the branches wouldn't break. Last year, the biggest and the one that produced the most, had only miniature peaches on it. The other one was fine. This year, the biggest tree has nothing at all. The other one is showing fruit as normal. Any suggestions as to why one has stopped producing?

Several reasons not enough nutrients uneven auxin balance, try pollading it stimulates the trees to grow quicker. good luck!
