You do realize that what you've bought is a
tree, right? The
dwarf type can be grown in a container of 1 to 3 feet in diameter, but the
full-sized type will become quite large, about 25 to 30 feet tall.
They need full sun, but cannot withstand temperatures below about 55º F. They don't like to be in wet soil, so be sure you use a fast-draining planter mix when you repot yours. If you have the full-sized type, be sure you plant it in a well-drained place in your yard.

"Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?" - Douglas Adams
