It
is always best to plant your tree as soon as possible after you receive it in
the mail (and within a week or two).  If you need to wait a few days, no
problem, simply take your tree out of the shipping box right away and stand it
upright.  Remove the wrapping around the pot (this was just to keep
everything in place during shipping).  Keep it in the shade and out of the
sun - a garage or shaded porch is perfect.  Drizzle a little water in the
pot every couple of days but not too much.
