I just came into possession of four dahlia tubers that have not been planted this year. It's too late to plant them and have them bloom before first frost this fall, but I need to know if they will survive if I store them now in a cool, dry place.

What should I do to store them, OR should I go ahead and plant them now? I don't usually dig up my dahlias in the Fall -- I just mulch very heavily, and they seem to be coming back just fine.

Anyone with advice would be much appreciated. I'm new at this, and I really want to be sure these four dahlias survive until next spring.
