What can I do about an area of garden that once had a tree infected by honey fungus? The tree has long since been cut down, but nothing grows there. Is the honey fungus still in the soil and what can I put there that will stand any chance of survival. To add to complications the site is at the bottom of a slope on clay soil and is partially shady. I need to sort out this hole in my boundary with something that will grow, screen and hopefully look pretty. Any ideas?
