Hetty is correct these are in 3 gal pots now (not root bound yet) but they need the room if you want to get a great plant Its worth the investment to up the pot I learned the hard way i think some of mine i left in 1 gal pots and did not bloom. when they got to 3 gal pots the are shooting for the sky by the day and i am certain i will see blooms this or next year.
One very wise Lady
has told me and others "these are trees you know??"
the bigger the better....as long as you can protect them from cold. if you have very long cold temps you can uproot them for winter and replant in spring (i dont do it ) my winter is about 3-10 days long
.... no i have the room to leave in pots for now but looking at the ground hard they might meet the open earth next spring...
Hetty is great ( enabler
) sales person due to her wealth of knowledge
will put you down for that
