Stone fruit trees took a huge hit here in Michigan this year and my 3 little peach trees did not escape early blooming then frosting off of 100% the blooms. Oh boo hoo! Well now my trees look as healthy as they ever have because they hadn no peaches on them to support this summer. I had a big peach leaf curl problem last season but I was able to defeat that and had high hopes for this summer. Soooo! I want to prune them pretty hard to open up the center for next season and then cross my fingers. WHEN is the best time for me to do this?? It is my understanding that in January when everything is still frozen is the right time. Any peach-o-philes in here? Thanks in advance for any input!
