Light Requirements

Elytrigia smithii, commonly known as Western wheatgrass, thrives in full sun exposure conditions. It requires at least 6 hours of direct sunlight to grow and develop properly. Insufficient sunlight can cause the plant to become weak and susceptible to diseases.

Temperature Requirements

Western wheatgrass grows best in moderate temperatures, ranging between 60–75°F (15–24°C). It can withstand frost and drought conditions; however, these extremes can slow down its growth rate and affect its productivity. During the winter and summer, it becomes dormant and resumes growth when temperatures become favorable.

Soil Requirements

The plant is adaptable to various types of soil, provided they are well-draining and contain adequate nutrients. It favors loamy or clay loam soils with a pH ranging from 5.5 to 7.5. Western wheatgrass can tolerate saline soils and is highly resistant to alkalinity, making it ideal for arid and semi-arid regions. It is essential to ensure adequate soil moisture levels, especially during the growing season, to aid root development and support lush growth.

Cultivation

Elytrigia smithii (Rydb.) Nevski is a hardy and adaptable plant that thrives in well-drained soil and full sun. It can grow in a range of soil types, including sandy, loamy, and clay soils. However, it prefers alkaline soil conditions, which are commonly found in arid and semi-arid regions.

The plant is best propagated in the spring using seedlings. The seedlings should be planted at a depth of about 0.5 inches into soil that has been loosened to a depth of 3-4 inches. The planting area should be watered immediately after planting to encourage rapid root establishment.

Watering Needs

Elytrigia smithii (Rydb.) Nevski is a drought-tolerant plant that does not require frequent watering once it is established. However, it is important to keep the soil moist during the first few weeks after planting to help the roots establish firmly in the soil. After that, the plant can survive with occasional watering. It is important to avoid overwatering, as this can lead to root rot and other fungal diseases.

Fertilization

Elytrigia smithii (Rydb.) Nevski does not require regular fertilization, as it is adapted to nutrient-poor soils. However, if the soil is particularly poor or if the plant is not growing well, a slow-release fertilizer rich in phosphorus and potassium can be applied in the spring before new growth begins.

Pruning

Elytrigia smithii (Rydb.) Nevski does not require regular pruning, as it is a low-maintenance plant. However, to maintain a tidy appearance, any yellow or brown leaves can be removed as they appear. Additionally, if the plant spreads too far beyond its desired boundaries, it can be pruned back in early spring before new growth begins.

Propagation of Elytrigia smithii (Rydb.) Nevski

Elytrigia smithii (Rydb.) Nevski, commonly known as western wheatgrass, is a perennial, cool season grass that is native to western North America. There are different ways to propagate this species, which include seed propagation, transplants, and vegetative propagation.

Seed Propagation

Seed propagation is the most common way to propagate Elytrigia smithii. The seeds are typically planted in the fall or early spring, about 1/4 inch deep in a well-drained, sandy loam soil that is moist but not wet. The ideal temperature for seed germination is 65 to 75 degrees Fahrenheit, and germination typically occurs within 14 to 21 days.

The seedlings should be thinned to one plant per square foot once they reach a height of 2 to 3 inches. Western wheatgrass is a slow-growing species, and it may take up to three years for the seedlings to become established.

Transplants

Transplants are another way to propagate Elytrigia smithii. Transplants are typically used when there is a need to establish a new stand of western wheatgrass quickly. The transplants are typically grown from seeds in a greenhouse and then transplanted into the field when they are 4 to 6 inches tall, and the soil temperatures reach 50 degrees Fahrenheit or higher.

Transplants should be planted in a well-prepared seedbed and should be watered regularly until they become established. It may take up to two years for transplants to become fully established.

Vegetative Propagation

Vegetative propagation is a technique that involves the use of vegetative plant parts, such as rhizomes and stolons, to produce new plants. Elytrigia smithii has a rhizomatous growth habit, which means that it produces underground stems that may be used for vegetative propagation.

The rhizomes can be dug up and divided into sections, each of which has at least one growing point. The sections can then be replanted in a well-prepared seedbed and watered regularly until they become established. Vegetative propagation may be useful for establishing western wheatgrass in areas where seed propagation or transplants are not feasible.
