Propagation Methods
The following are the methods used to propagate Artemisia cana Pursh var. viscidula Osterhout:
- Seed Propagation: Seeds can be sown in the fall, directly into the soil or in pots.

The seedlings can be transplanted outdoors in the spring.
- Cuttings Propagation: Cuttings from the plant can be taken in late spring or early summer. The stem cuttings should be 3-6 inches long, with a few leaves and no flowers. Remove the lower leaves and dip the cut end into rooting hormone powder. Plant the cutting in a well-draining potting mix and water it thoroughly. Cover the pot with a plastic bag to retain moisture and place it in a bright, but indirect light. Rooting can take up to four weeks. Once the cutting has rooted, it can be transplanted into a larger pot or outdoors into the ground.
- Division Propagation: Mature plants can be divided in the fall or early spring. Dig up the plant and gently separate the root clumps. Replant the sections in well-draining soil and water them thoroughly. Divide the plant every few years to maintain its health and vigor.
By using these methods, gardeners can easily propagate Artemisia cana Pursh var. viscidula Osterhout and enjoy its beauty in their gardens.
Disease Management
