Bump

Since no one in that planting zone responded, I'll give you my two cent Monopoly money...

Once you dig the tubers, I would not replant the disturbed roots until spring. Here's my theory on why-- there are lots of fine hair roots that feed the tuber, providing it with an immune system of sorts. If you sever that feeding system in a non-growing time of year, that tuber might rot with the winter rains. I wouldn't want to risk it.

Lots of growers in nice year-round climates dig every fall with the rest of us cold-zoned growers, as it allows them to divide and in turn get more vigorous plants. It also avoids rot when the plant is not actively growing.

Hope this helps, and that someone in your zone adds their thoughts.

Cheers!

Thank you cc!! I read the Georgia dahlia society on the internet and it said to wait til spring to dig up and divide. I sooooo hate to store things over winter so I think I will just wait til April and dig them up then and divide. I'm hoping they will be fine. Your advice was very helpful in steering me in the right direction if I do decide to divide now. Thanks for your help!! Judy
