Propagation of Phacelia nevadensis J.T. Howell
Phacelia nevadensis J.T. Howell is a member of the borage family that is native to the western United States. This plant has fragrant, bell-shaped flowers and is commonly called Nevada phacelia. Propagating this plant can be done through several methods.
Seed Propagation
The most common method of propagating Phacelia nevadensis J.T. Howell is through seed propagation. The seeds can be collected from the mature plant or purchased from a seed supplier. The seeds should be sown in the early spring or fall in a well-draining soil mix. Cover the seeds with a light layer of soil, water thoroughly, and keep the soil moist until germination occurs. The plant will typically flower in its second growing season.
Cuttings Propagation
Propagation through cuttings is also possible but can be more challenging. This method is typically performed on mature plants. Choose a healthy stem from the parent plant and cut it just below a leaf node. Dip the cut end in a rooting hormone and insert it into a well-draining soil mix. Water the cutting thoroughly and cover it with a plastic bag to create a humid environment. Keep the soil moist and the cutting in a warm location until roots develop. Transplant the new plant to a larger container or into the ground.
Division Propagation
Division is another method of propagation that can be used for Phacelia nevadensis J.T. Howell. This method involves dividing the parent plant into smaller sections, each containing roots. This should be done in the early spring before new growth appears. Using a clean, sharp tool, divide the plant into sections and replant them in a well-draining soil mix. Water thoroughly and keep the soil moist until new growth appears.
