This is the first year my peach tree has had fruit. It's about 3 years old and 10' high. The peaches are very small and staying green with no spots but no fruit growth, just small green walnuts. I'm not sure what type they are. We are in SC. Any suggestions?

Peach trees need to be pruned and thinned well to produce fruit. If your tree is at least 3 years old and it carries the immature fruit throughout the season, that may be your problem. This article will help: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-thinning.htm
