Should you dig your dahlias or not? Enthusiasts dig them up every autumn when the clocks get turned back. They dust the tubers with fungicide, divide them up and finally store them in a cool place in slightly damp vermiculite. For those of us not so dedicated to our dahlias we can leave them in the ground provided that the soil is well drained and doesn’t freeze. A little patch of plastic can help keep the spot dry over winter. For more dahlia growing tips go to the Puget Sound Dahlia Association website
