I tip my hat to you. hello

I live in Northeast Georgia and didn't know a thing about Dahlias until last year when the only two I planted bloomed. This year, one came back (Duet) and one didn't (Firebird). The Firebird was in a container and it may have been too cold or or maybe that variety isn't hardy.

I've visited 4-5 online Dahlia tuber stores and none of them list a recommended hardiness zone. I walked through my friend's garden just this afternoon and she showed me 4-5 varieties that she said are "perennial" but I'm not seeing any indication on these sites and I don't want to lift tubers unless I'm dividing them.

Can anyone give a newbie some advice on how to get more of these beautiful plants that will come back year after year?

Thanks in advance for your time and help! Thank You!

Dahlias are hardy in zones 8-10.

Sounds like you are on the border, which usually means that some will overwinter and other will not.

Of course, if you have a severe (cold) winter, most if not all will die.

I am not aware of any dahlia studies that evaluated borderline hardiness.

P.S. I moved from SE Michigan in 2007 (I lived in many places between Warren and Kalamazoo lol)-- it's a whole different climate [world] down here and we've been renting until recently. We bought in Dec 2015 and I'm starting the journey of creating a garden and Dahlias are definitely going to be a part of it.

I have heard of people who manage to overwinter their Dahlias in the ground even in zones 5-6, with lots of mulch to protect them. However, they really should be lifted and divided at least every 2-3 years to keep them healthy.
