I have 3 mulberry trees that are over 30 years old and have never fruited. They were purchased from a nursery in sets of 2 (one died within a year) and we were told at the time of purchase that there was one female and one male for cross pollination. Obviously we were misinformed since we have never gotten fruit from any of the trees.
My question is does any one know where I can get some scions from fruiting trees so I can graft them onto my trees to eventually get some berries?
