Propagation of Aster cordifolius L. var. incisus Britt.
Aster cordifolius L. var. incisus Britt. can be propagated by both seed and division. Both methods are effective and relatively easy.
Propagation by Seed
The seeds of Aster cordifolius L. var. incisus Britt. can be sown directly in the ground in the desired location. However, it is best to start the seeds indoors in pots or seed trays. The seeds should be sown in a well-draining potting mix and kept moist. They should be kept in a warm location with indirect light. The seeds should germinate within 2-4 weeks. Once the seedlings are large enough to handle, they can be transplanted to their permanent location.
Propagation by Division
Aster cordifolius L. var. incisus Britt. can also be propagated by division. This can be done in either the spring or fall. The plant should be lifted from the ground and the root system carefully separated into sections. Each section should have a healthy shoot system and several roots attached.
