My dwarf peach tree is 2 yrs old and it appears that the trunk is splitting a bit. What do I do?

Splitting most commonly occurs in freezing weather. If the wound is not weeping or splitting further, then you should just leave it alone to heal on its own. If the split is widening, you can try protective paper (sold at nurseries) to help hold it together while it heals. Do not cover the wound with tar or any other permanent substance as this can trap disease in the wound.
It could also be an indication of peach tree borer. Here is an article that you may find helpful: https://www.gardeningknowhow.com/edible/fruits/peach/peach-tree-borer.htm
If the splitting is in winter or early spring, the best thing to do would be to paint the trunk with a white latex paint to about an inch below the first limb.
