No Verdun, they are not potted - they are a bunch of tubers about double the size of a large cauliflower* - dug straight out of the ground today, with only a small amount of foliage attached. They were in full flower so seemed a shame to cut the stalks off but apparently the clump was quite large & floppy so not practical to dig them up intact.
The clump has lots of tubers packed together. Can they be divided, if so, when? I have never grown Dahlias but always wanted them.
I don't have a GH - just my brick shed (see photos.) I live on the edge of Bournemouth so not usually very hard Winters. Saying that - frost got my container of Pelargoniums last year - my brother's (in his garden border under a tree) survived ok.
Bit mindful of mice as some seed packets in the shed were nibbled last Winter by something!
I do intend to make a cold frame but haven't done it yet!
* peculiar comparison, I know, but couldn't think of anything more appropriate to give example of size!
