Raspberry patch dying out
My parents used to have a nice patch of red raspberries but in the last two years they have really gone downhill. They are putting up sparse sprouts this spring and I've been digging out dead crowns in many spots. Any ideas what could cause this? I don't know what variety they are although I know they are fall bearing. I think they were originally just passed along from someone else. Perhaps they should start over in a new location with a newer cultivated strain. Any advice?
