Propagation of Artemisia glauca Pallas ex Willd. var. dracunculina (S. Wats.) Fern.
Artemisia glauca Pallas ex Willd. var. dracunculina (S. Wats.) Fern. can be propagated through various methods including seed propagation, division, and stem cutting.
Seed propagation
Seeds of Artemisia glauca can be sown directly into the soil in the spring or in the fall. The seeds should be planted just below the surface of the soil in a well-drained area that receives full sunlight.
After planting, the soil should be kept moist until the seeds germinate, which can take up to two weeks. Once the seedlings reach a few inches in height, they can be transplanted into their permanent location.
Division
Artemisia glauca can be propagated through division. This involves lifting a clump of the plant and separating it into smaller pieces, each with a portion of the root system.
The best time to divide Artemisia glauca is in the spring or fall when the plant is not actively growing. The divided pieces can then be replanted in a well-drained area that receives full sunlight.
Stem cutting
Stem cuttings can also be used to propagate Artemisia glauca. This method involves taking a cutting of the stem, usually in the spring or early summer, and planting it in a well-drained area with full sunlight.
The cutting should be about four inches long and stripped of its lower leaves. It can then be planted in a well-drained area and kept moist until it roots. Once the cutting has established roots, it can be transplanted into its permanent location.
