Seed Propagation
The best time for seed collection is in late summer or early autumn when the seed heads have dried out.

Cutting Propagation
Cutting propagation is possible through root division. This method is best done in the spring when the plant is actively growing.
The best way to divide the roots is to dig up the entire plant and separate the roots. The plant can then be replanted in several different areas. Be sure to water the plant thoroughly after replanting it. The plant may need to be supported until the roots become established in the new soil.

Another pest that may affect the plant is the spider mite, which feeds on the plant's juices and causes leaves to become speckled and discolored.
A natural way to manage whiteflies and spider mites is to introduce beneficial insects, such as ladybugs and lacewings, which feed on these pests. Regularly hosing down the plant with a strong stream of water can also help to wash away whiteflies and spider mites. In severe cases, applying an insecticide may be necessary.
