Southwest Yard and Garden teaches viewers hot to grow blackberries in Southern New Mexico. Blackberries grow in high rain fall areas but they can work in the south west. They will need bee pollination so you need to make sure that you do not spray too much insecticide on them or you will kill of the bees. Make sure you pick the blueberries when they are dull and not when they are shiny. This will give them the maximum sugar content. Blackberries should grow in sandy soil or looser soil. You might run into problems with weeds because they can wrap around the plants. You should let first year steams grow but then next year you should cut them back to force all the energy on the can so it produces a bigger berry. You should cut it back about a third after one year.
