Do you dig yours up? I dont normally...but did..now what?? LOL
There's some info on storing dahlia bulbs here: http://www.ext.nodak.edu/extnews/hortiscope/flowers/dahlia.htm
and here: http://www.dahlias.net/dahwebpg/TuberStor/TuberStor1.htm
We don't plant dahlias JUST becasue one has to dig them up if one wants them to grow the next year around here. Ditto glads and a lot of other tubers/bulbs like that. Lack of suitable storage space is part of the issue but also we just have more than enough to do in the garden without digging up bulbs and replanting them every season!
I found this link about storing them...http://www.dahliabarn.com/dahlia-care.phtml
