Q.pruning peach trees in August
Can I prune my peach trees in August, and if so, how do I do it to get more fruit?
August is generally not a good time for pruning, which should really be done once the tree goes dormant or in early spring. The best time of year to prune is in February, once the danger of frost has passed but before any fruit has begun budding/blooming. That said, it will not hurt to prune out what is dead and any weak branches, especially if they are crossing other branches.
Once the clean up pruning is done, if you have any fruit left on the tree this year, you need to thin it out. This article will help with that: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-thinning.htm
