From their website:
•Our trees are 30 - 32" tall and about one year old.
•We grow our trees in the same pot that we grow commercial trees. It is a 4 inch square pot that is 14" tall.
•This "sleeve" is perfect for shipping because you get the entire root ball and soil rather than "bare root."
•Getting the soil with the tree greatly increases your success with your new citrus tree.
•The pot is equivalent to a "1 gallon" capacity.
•We grow a standard size, budded tree, not a rooted cutting.
