We have just had a 40ft Scots pine removed from our very small garden. The tree surgeon said that the soil would be very acidic due to the pine needles. We want to plant a hazel tree in its place, and some shrubs around it, but I am not sure where to start - do we dig the whole area out and get some new topsoil? The stump has been ground out, but the roots from the pine tree are still there. We will plant the hazel to one side, obviously, but am worried that it may not survive.
