Hi, a question about raspberries: When we moved into our house about 5 years ago, there were what I thought were some raspberry vines in the backyard, close to the woods our yard backs to. So, we have left them in the yard, thinking it would be nice to have raspberries, but they have never grown any berries. They are starting to take over that part of the yard, and I'm thinking of digging them up and getting rid of them. I checked the leaves of these plants against some leaves of confirmed raspberry plants that grow wild in the woods by our house, and they look identical. Are there such things as raspberry plants that never or rarely yeild berries, or is there a weed that is a look-alike to raspberry plants?
Thanks for any information you can provide!
