Step 1 – Discard any unattached pieces of old roots or crown remnants. If planting into the garden itself, wait until night temperatures stay above 45 degrees. In pots or containers, you can plant immediately using one ten to twelve inch pot per root.
Step 2 Plant the clumps with the roots facing downward and the old stem upwards. Your hole should be deep enough to accommodate the root. Leave the old stem portion above the soil line. The crown will be just below the surface. This is where the stem meets the root. Full sun is best.
Step 3 - Water them thoroughly. Once they sprout water again. Keep moist in summer.
Step 4 – In pots or containers, you can plant immediately using one ten to twelve inch pot per root. You should place the plants outside and leave them there as soon as evening temperatures stay above 45 degrees.
Step 5 - Planted now each clump will produce impressive flowers in early summer through early autumn and every year thereafter. They are hardy in the winter to about 35 degrees.
