Help me choose small tree for poor drainage site
I have a Coral Bark maple that I planted last spring and it is slowly declining. When I dug the hole, I dug it too deep, and decided that I would put in some compost and top soil to help with drainage(I have clay soil). Little did I know I was actually hurting it by doing this. The area holds too much water and the tree just isn't growing. The leaves this year look small and droopy. I have decided to take the tree out and put it in a large pot in my back yard as I think it will fare better.
I still want to put a tree on this site because it is a landscaped area of my front yard that really needs some height. My question is, what should I do with the site? Do I choose a tree that adapts well to wet soil, or try to amend the entire area. It does need to be a small tree not growing taller that 20ft.
