Kyle,
Thanks for those tips. I do hope to have the stump ground out soon. It was supposed to have already been done, but the fellows who were to do it turned out to be grifters who were asked not to return.

I honestly doubt they were capable of deep grinding anyway.
They are currently sheltered in a couple of flower beds that get morning/mid-morning Sun. The azaleas and myrtles should keep the wind away while allowing some Sun in. I figured that was a good area since it is where the naturally-planted water maple seedlings tend to do well.
Once I choose one to transplant, should I put something around the seedling to prevent any wildlife or other damage? They are awful small plants currently... a foot tall, tops.
