Autumn Blaze maple rescued from WalMart

In May of 2005 I rescued an Autumn Blaze maple from the local WalMart.

It was a small (6') containerized tree, and was badly neglected, lying on its side in the parking lot, drying out in the hot sun.

I think I paid $6 for it.

When I got home, I remembered we were leaving for vacation in 2 days, and would be gone for 10 days.

I knew next to nothing about how to plant a tree properly, having never previously done so.

Looking back, I did nearly everything wrong.

I dug a deep hole (about 3 feet) through a surface layer of hardpan clay into the sandy/rocky soil below, and backfilled it part way with rich black soil and organic matter taken from a fenceline populated by old-growth trees and brush. I removed the tree from the container, did not free up the roots, placed it into the hole on top of the backfill soil, backfilled around it to the top of the container soil level (which was about 8" below ground level), supported it with 3 stakes and guy wire, watered it heavily, and left on vacation.

So bottom line:

- the root flare was not exposed (it was below soil level in the container)

- the roots were probably somewhat pot-bound (I don't remember for sure... I didn't know enough to even notice)

- when all was completed, the tree was at the bottom of an 8" deep hole about 2 feet in diameter

For the first 5 or so years, the tree struggled mightily. It developed a bad case a anthracnose, and every year it had a very short growing season before it gave up and just clung to life until the hot summer was over.

Then it finally got over the anthracnose, and for the past 4 years has been growing like a weed. This year, it's still putting out new growth in the middle of July.

It's now about 20 to 25 feet tall, and it puts on quite a display in the fall.

My question is: in view of the improper planting, what are the long-term prospects for this tree, and is there any intervention I should be considering to mitigate the effects of the mistakes I made?
