When should we dig out the tubers of Dahlia?
I just started gardening from last spring and I planted a lot of beautiful Dahlias. Someone told me that I should dig out the tubers before winter comes. When should it be? Thanks.

In cold climes, the tubers won’t survive. Remove them, store them in a cool place (basement) in wood shavings or wrap loosely in newspaper. Do it as soon as the blooms are gone.
Just remember where you put them. I dug up my begonias last year and still can’t find them
You should wait till the first frost makes the leaves wilt, then dig them out and store them in a cool, dry place. You can start them in a grow-bag in a bright spot indoors in early April, then if you plant them out you get flowers earlier.
I work at a private greenhouse/garden and we are going to dig our dahlias any day. Ours were covered and protected from frost so the foliage just died due to a freeze we had. Dig your dahlias soon, definitely before the ground freezes.
If you live in an area with mild winters, you don’t need to dig them up as long as they are in soil that drains well. Otherwise, dig them up before a hard freeze. Dry them out for a couple of days, then put a layer of peat moss in a box. Add the tubers, then cover with more peat moss. Keep in a cool, dry place such as a garage or basement through the winter, keeping the peat moss just barely damp. Plant in spring when danger of frost is past.
