In many areas blackberries grow profusely with no help from us. However, if you are thinking of planting some berry bushes in your garden, then this information can be helpful for providing you with a bumper crop. This is a guide about growing blackberries.
I have no idea if mine are wild or domestic as they came in with the city's free "organic" mulch. There are too many canes, but I managed to weave/wrap them all around and up a large tomato cage and to keep them green, but no fruit. I heard they can be awful in a garden. Should I cut them out of the garden before next Spring? I don't have a lot of room for them and yet, they seem to stay alive on the cage. They have terrible thorns and no berries.
I don't want them too much. ;< ( yet I hate to kill a fruit bearing plant. This was the year from Hell, remember, yet I watered regularly, but did not know about fertilizing with compost, so I didn't.
I've said that my passion is propagation. It is. A close runner up would be experimentation. My latest experiment is standardizing blackberries.
This is just a warning to those of you who are interested in planting blackberries. Choose your site carefully. They are terrible to get rid of if you don't want them in a particular place in your yard or garden. Once they establish themselves, they pop up everywhere.

Oh Patricia, you are so very right! I planted one small plant 12 yrs ago and I'm still mowing down all the little sprouts that keep showing up! My suggestion is that if you want to plant blackberries (or raspberries or any other such berry) plant them in a container. That way they can't spread.
One year I even took a small plastic kiddie pool (about 6 feet in diameter) and planted one blackberry and one raspberry vine in the middle of it. Worked out great! I went to a yard sale and picked up a wooden ladder for next to nothing and trained the vines to grow up that. Wish I had thought to take a picture of it.
How do I get slips from thornless blackberries?

In the spring when the blackberry leaves come out, draw the tip of the cane onto the ground and secure it with a chunk of wire that you have cut to resemble a large hairpin. A piece 7 or eight inches long that has been bent double will do quite nicely. Do this for as many slips as you want in the fall. In the fall cut the new canes free of the old ones and dig them up and replant.be sure to cover with mulch if it gets really cold where you are.
