What size pot
I have a Glenn in a ceramic pot (about 8-10 gallon) and it's growing like a weed at 7'+ with four nice branches at the top after topping it a few months ago. I am going to keep it in a pot for the next few years but I need to know more about pots for them.
My question is: How large should the pot ultimately be? I want to use ceramic so there's less chance of them blowing over. Right now there's some decent clearance sales going on at the garden centers and I want to buy in advance.
