Two years ago I transplanted some of the wild blackberries from outside Albany to my place in Christmas Valley. Only a few of fifteen plants are getting blossoms. Are some plants male and some female that produce fruit?
I have not trimmed back the canes ever. The plants are 2 plus years old. Only a couple of the plants put on blossoms and then fruit. So my question remains. Are some plants male, and therefore will not put on blossoms ever?
