Q.Do Blackberries spread?
I have raspberries and they would take over the yard if I let them. Wondering if Blackberries are the same.
There are probably hundreds of varieties of blackberry, some of which could be rampant and invasive in your area, and some of which are not. For information on which would be good cultivars to plant, and where to get them, you can consult your county Extension Service.

Here's an article on pruning berry bushes (would apply to red raspberry also): https://www.gardeningknowhow.com/edible/fruits/blackberries/blackberry-pruning.htm
An alternative is to plant berries in containers: https://www.gardeningknowhow.com/edible/fruits/blackberries/blackberry-pruning.htm
