Planting a Black Gold cherry tree in a defunct old root system.
We had a dead 40 foot ash tree removed three years ago. I want to plant the cherry tree about 6 feet from where the ash was. I'm planning to go in with a mattock to hack up and remove the old root systems so the tree has the best chance possible. Has anyone done this before, and can you tell me how deep and wide I need to go to accommodate our new fruit tree?
