I’m giving up on some variety of summer raspberry I have (I transplanted them from my grandma and don’t know what they are). They only produce enough fruit if I water them. When I get the time and weather, I’m going to mow them, and keep them mowed.
I have some fall raspberries that are growing under/around an oak tree that produce a lot of fruit and don’t seem to be bothered by birds or much of anything. I like being able to mow them off each winter and start with new canes and more berries late summer/early fall each year.
