Dahlia Bulbs

This year I planted a few Dahlia bulbs and I am wondering about keeping them for next year. I know I have to take the bulbs out of the ground but do they have to stay in dirt with some foliage or what? Mary Jo

    I planted Dahlias for the first time ever this year and I must say I do not think I will keep mine or ever plant them again. Perhaps it was the drought conditions we have....????

    we take the bulbs out for clients. we remove all of the soil, wrap in news papper, place in 5 gallon buckets with sand covering them and then keep them in a cool dry envirrionment for the winter,

    In zones 8 and warmer, dahlias can be overwintered in the ground. Otherwise you need to lift them. After a killing frost, cut the foliage back to 2 to 4 inches above the ground. Lift each clump separately with a spading fork and gently brush the soil off the clump of tuberous roots. Spread the clumps in a well-ventilated, shaded area to cure for a few days. (Do not leave the tubers in full sun) Pack each clump upside down in a ventilated box or basket using slightly damp vermiculite, perlite or peat moss to cover the clumps. If you grow more than one variety, make sure you label them! Ideal storage temperatures are 35 and 50 degrees. Take a look at them every now and then and if they're starting to shrivel, sprinkle lightly with water.
