Propagation of Artemisia californica Less.
Artemisia californica Less., also known as California sagebrush, can be propagated through multiple methods:
Seed Propagation
The plant produces seeds in the fall, which can be collected and sown directly into the soil. The seeds should be sown in a well-draining soil mix and kept moist until they germinate in 2-4 weeks. Seedlings should be transplanted once they are large enough to handle, typically after 6-8 weeks.
Cuttings Propagation
Artemisia californica can also be propagated through semi-hardwood cuttings. Cuttings should be taken in the summer or fall, when the plant is actively growing. Choose a non-flowering stem, remove the lower leaves, and dip the cut end in rooting hormone. Stick the cutting in well-draining soil mix and cover with plastic to create a greenhouse-like environment. Water the cuttings regularly and remove the plastic cover once roots have formed, typically after 4-6 weeks.
Division Propagation
Artemisia californica can also be propagated through division. This method is best done in the fall or early spring. Dig up the plant and gently separate the roots into smaller sections. Replant the divided sections, making sure to keep the soil moist to encourage root development.
Regardless of the propagation method, Artemisia californica prefers well-draining soil, full sun to partial shade, and regular watering until established. With proper care and maintenance, this plant can easily propagate and thrive in a variety of settings.
