These are good questions. Most likely if you dug the stump out. There may
be some woody roots that are left without and energy source. They will be
predisposed to rot decay fungi. As long as the tree is healthy, you are
planting, you plant correctly, mulch correctly, I would wait until the
second growing season before any stem pruning or fertilization,you should be
OK. I guess some organic fertilizer would be fine. Do root prune at
planting time to remove torn woody roots. With a sharp tool and straight
across like the end of a straw. Look up "root pruning" at pruning link
below. Other than that -

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

My dwarf pie cherry tree has died, perhaps from old age. At least I found
no patent signs of injury or disease. We removed it and dug out the stump
(no easy task on an older tree).

I want to put in a replacement, but not a dwarf. The place we had the old
one is ideal. Is there some reason I wouldn't put the replacement there
next spring, or something I should do to prepare the site?
