We bought this house two years ago, and it came with thornless raspberries and blackberries in the veggie garden. I don't know what kind of plants they are, as in the name of the variety, but they are delicious! However, the raspberries are taking over, and I don't know what to do with them. I've never grown them before, and I need some advice on how to control them. I've converted the veggie garden into a daylily garden, and moved the veggies to a new area. I would eventually like to transplant the raspberries and blackberries to a new area, but I'm nowhere close to being ready for that. The problem I have now is that the raspberries are coming up all over the garden, and I can't seem to stop them. I decided early this year to cut them almost to the ground, along the area where they were originally planted, but that seems to have just put them into overdrive on spreading. The blackberries are much better at staying mostly put.
I'm getting desperate, and need some help! Is there a way to stop them from spreading everywhere? I've tried digging up the new plants, but they just seem to break off from the roots that must be a lot deeper down. I've read somewhere that cutting them off at the ground may help, but that hasn't worked as planned. It's going to be a raspberry jungle out there before too long!
Any help or suggestions would be most appreciated!
