Clint ...
Let me take a step back ... would you say you live in a more humid climate ? My climate is quite arid so keeping pots moist in triple digit temps, even in the shade is hard.
Do you get the plants into the ground before winter or how do you over winter them ? I would have to over winter them outside. Would it be safer to have them in the ground ?
I'd really, really like to go for this sale, so if you can talk me into this, I want to do it ..
