How do I amend hardened clay soil that won’t drain in order to plant a tree?

Question

Planted a hybrid ornamental cherry tree after removing some clay soil and adding (bagged) garden soil. Got a lot of rain and wind a few days later which flooded the hole due to bad drainage. The tree blew down to its side since the stakes loosened in the mud. How can I fix this problem?
