I purchased an 8-foot Holly tree last fall and it was beautiful. I planted it on a clay slope and the ball of the plant was exposed. A couple of months ago, I was concerned this would cause problems, so I boxed it in with drainage rocks and shrub soil. Within the last month I have noticed the tree is turning a yellowish tint on the outside and the leaves inside the tree are brown and falling off. Do you know why this would occur?
