Q.The peaches on my dwarf tree are big and beautiful but never ripen. What can I do?
The peaches on my dwarf tree look great. I cull, spray all season, but the fruit either falls off or stays hard as rock. I’ve tried ripening fruit indoors, in paper bags, etc., but they get soft on the outside and rot rather than ripen. What can I do to get ripe fruit?
