Since I don't have a lot of space, I decided to plant my blackberry bushes in a raised bed.
My plan is to make it 4ft wide x 10Ft long, using 2 X 10s. with newspaper or cardboard under the dirt to kill the grass. With 50/50 compost and topsoil.
I plan to grow Arapaho blackberry bushes which are erect thornless.
Any advice at all about this plan? and how many bushes should this space hold? Can I plant stuff like strawberries in between them?
