This summer is the first time I planted Dahlias which were absolutely beautiful. Now that fall is upon us I need to know had do I care for them during the winter. Do they need to be cut down? if so, How far do I cut them?

Your Dahlias should be finished blooming by now. Cut remaining flowers from plants, and then wait for frost to kill the foliage. Cut dead foliage down to the soil line, dig the tubers, and store them for the winter in a cool, dry area in bags of slightly moist peat moss. Tubers can be separated now or left in clusters. I divide mine in spring, after new buds begin to swell.
