Sorry I didn't read your post earlier bberry. I don't know about Mirabelle plums but yes you can grow Mulberries in Maine. I live in Randolph (across the river from Gardiner) and I have two White Mulberries that are now five years old and completely Winter hardy. They fruit very well as a matter of fact. I got them from St. Lawrence Nursery. |
