It is important to avoid over-fertilization, as this can lead to excessive foliage growth and weak stems.

Pruning Elymus glaucus Buckl. ssp. jepsonii (Burtt-Davy) Gould

Elymus glaucus Buckl. ssp. jepsonii (Burtt-Davy) Gould does not require regular pruning. However, it can be beneficial to remove dead or damaged leaves to promote healthy growth and appearance.

Additionally, if the plant becomes too large or begins to encroach on other plants, it can be divided and transplanted to a new location. Division should be done in the early spring, before new growth begins.

Propagation of Elymus glaucus Buckl. ssp. jepsonii (Burtt-Davy) Gould

Elymus glaucus Buckl. ssp. jepsonii (Burtt-Davy) Gould is a beautiful, long-lived, perennial grass that is native to the western United States. It can be propagated by division, seed, or rhizomes. Each propagation method has its own advantages and disadvantages, and the best method depends on the specific needs and circumstances of the gardener.

Propagation by Division

Propagation by division is a reliable method to create new plants that are genetically identical to the original plant. This method is best done in the spring or fall when the plant is dormant.

To propagate by division, dig up the plant and separate the crown into sections with a sharp knife or spade. Make sure each section has at least one bud or shoot. Replant each section in a suitable location and water well. Divided plants may take some time to establish, so it is important to water them regularly and keep them in a shaded area until they have formed new roots and started to grow.

Propagation by Seed

Propagation by seed is a cost-effective way to create a large number of plants, but it can take a longer time for the plants to mature. To propagate by seed, collect seeds from the existing plant when they are fully mature and dry. Seed collection is usually done in the late summer or fall.

Clean the seeds by removing any chaff or debris, and store them in a dry, cool and dark place until they are ready to be planted. Plant the seeds in a well-drained soil mix in pots or trays. Water the seeds regularly and keep them in a warm, bright, and humid location until they germinate. Once the seedlings are large enough, transplant them into individual pots or containers.

Propagation by Rhizomes

Elymus glaucus Buckl. ssp. jepsonii (Burtt-Davy) Gould also spreads through its underground rhizomes, which are modified stems that grow horizontally and can produce new shoots. Propagation by rhizomes is an effective method to create new plants that are genetically identical to the parent plant.

To propagate by rhizomes, dig up the plant and carefully cut off sections of the rhizomes with a sharp knife. Make sure each section has at least one bud or shoot. Replant each section in a suitable location and water well. Rhizomes may take some time to establish, so it is important to water them regularly and keep them in a shaded area until they have formed new roots and started to grow.
