Thanks Arlene.
So how do you keep them in their own area? That is my problem right now! I was thinking of a barrier too, but that flashing worries me too much. I noticed that someone down the road had planted all of her raspberries in 5 gallon buckets last year, and buried the buckets in the ground. Sounds like a great idea for when I get around to moving these. I talked to her when she was just planting them, so she didn't know if it would work. Guess I need to check and see how it went, and if they escaped.
Now to figure out how to stop these beasts from taking over! I've dug deep, and haven't found any roots, but I know that they are down there somewhere.
