Not sure.
I would probably leave it alone, it's just because when digging it out again, too much soil gets disturbed
around the root system and perhaps most soil will fall off!

This planting is very crucial!....It took me two tries.
Kuhlmans has learned a great deal too, when I bought my first one, there was hardly any root system and
when taking the tree out of the pot, all potting soil just have fallen off, the tree never really leafed out
and died.
They replaced it for me the next year and they said that they leave the trees in the greenhouse for a while
until some roots will form before beeing sold.
When I picked it up, they told me not to take the tree out of the pot, make hole first, then set the whole pot
inside and cut put open so no potting soil gets disturbed.
This seems to work, if you have a poor root system when nurseries they came from have cut allot
of tap roots off and had hardly any time to grow new feeder roots.
