To Grow In Pots
I have some Dahilas that are growing in small pots right now and rather than plant them in the ground, I'd like to put them in large pots for the summer. These are the large size flowers/plants and not pot dahlias, which I already have growing and blooming in a large rectangular planter.
What size pot should I use for these tubers, which as I said already have some leaves on them? Please use diameter measurement. I have lots of different size pots that are available for me to use.
Thanks for your help,
