If I see a sprout problem after this, I plan on adding another yet deep layer of plastic barrier below that. Raspberries like to run about the place and constantly have to be tamed into one spot. Raspberries and blackberries need full sun and well-drained soil that's rich in organic matter to stay healthy and at peak performance. The runners have popped up everywhere. This was not exactly the location I would have chosen to plant them if I picked up a plant from the local home improvement storeâ¦but figured best to go with it than fight it since I was sure the raspberry plant would be more persistent.
