We dig and store our Dahlia rhizomes overwinter at Chicago Botanic
Garden with good rates of success using recycled bulb crates and sawdust
in a frost free location.

I believe there is a group of dwarf dahlias bred for bedding schemes
that are day length neutral. In Ft. Worth, Texas the rhizomes would
sometimes overwinter.

My mother's garden in Mesilla Park, NM used to have some of the typical
garden dahlias that would take 3 to 4 years to die out completely. It is
a high elevation with cooler temperatures at night with typical adobe
(heavy clay) soils.
