The new shoots are tender and easily broken, so handle gently. Cut the clump into individual tuberous roots with a sharp knife. Eyes are found where the tuberous root and the stalk of last season's plant join. If it is difficult to distinguish the dormant eyes, place clumps in a warm moist place for several weeks or plant in shallow trays to promote sprouting. Cut surfaces should be allowed to dry for several days or dusted with captan or sulfur before planting.
Dahlias are very sensitive to freezing temperatures.
Large tuberous roots may be planted about 2 weeks before the last spring frost date. Small tuberous roots and transplants should not be planted until all danger from frost has passed. Dig a hole 8 to 10 inches deep and wide enough to accommodate the tubers. Loosen the soil in the bottom of the hole and refill to a depth of 6 inches. Set the tuberous root on its side, with the eyes facing upward.
