I prepare beds for setting out annual plants each spring - snapdragons, zinnias, those sorts of things. Digging dahlias in the fall is just prepping the bed for next spring, to my way of thinking. In April, I can just rake in some fertilizer and plunk in the annuals, if I want to.
Washing off the dahlia roots, tossing the old ones and storing the healthy roots in peat moss for the winter is some bother but not a lot. Digging a hole deeper than I would for snapdragons and such is a bother but, at least, I don't dig as many holes to fill a bed .
Leaving them in the ground for the winter? Let's see, you can buy new dahlias for $6 or $7 each! Or, you can dig this year's clump of dahlias and separate each into 3 to 5 new plants . . .
I once asked a guy with a dahlia business in zone 6 if he ever advises people to leave their dahlia roots in the garden overwinter. He said, "Only under 8 or 10 inches of hay. . . !"
I leave dahlia roots in the garden every winter. The ones that I don't want to come back the next year. That never disappoints me -- they are always dead, dead, dead by spring.
