Light Conditions:
Elymus trachycaulus ssp. subsecundus is a plant species that requires full sun to thrive. It cannot grow well in shaded areas. Full sun refers to areas where there is direct sunlight for several hours during the day.
Temperature Conditions:
The plant can withstand cold temperatures and even thrive in cooler regions. It can tolerate temperatures as low as -40 degrees Celsius and can grow well in areas with an average temperature of 10-20 degrees Celsius.
Soil Requirements:
Elymus trachycaulus ssp. subsecundus requires well-draining, sandy, or loamy soils to grow well. It can also grow in clayey soils as long as they are well-drained. The plant needs slightly acidic to neutral soils with a pH range between 6.0 to 7.5. It is also tolerant of saline soils and can grow in areas with a high salt content.
Cultivation
Elymus trachycaulus ssp. subsecundus is native to North America and can be found in dry prairies, sand hills, and open forests. It grows best in full sun or partial shade in well-drained soil with a pH between 6.0 and 7.5. The plant is tolerant of drought, heat, cold, and wind. It can be propagated by seed or by dividing established clumps in the spring or fall.
Watering Needs
While Elymus trachycaulus ssp. subsecundus is drought tolerant, it still requires regular watering, especially during its establishment phase. Water the plant deeply once or twice a week during dry spells, making sure the soil is thoroughly saturated. Avoid overhead watering, as the plant is susceptible to fungal diseases.
Fertilization
Elymus trachycaulus ssp. subsecundus does not require a lot of fertilization. Applying a slow-release fertilizer once a year in the spring when new growth appears can help promote healthy growth and development.
Pruning
Elymus trachycaulus ssp. subsecundus does not require pruning, as it is a low-maintenance plant. However, removing dead or damaged foliage can enhance the plant's appearance and health. It is best to prune in the spring before new growth appears.
Propagation Methods for Elymus Trachycaulus (Link) Gould ex Shinners ssp. Subsecundus (Link) A. & D. Löve
Elymus trachycaulus (Link) Gould ex Shinners ssp. subsecundus (Link) A.& D. Löve, also known as slender wheatgrass, is a native perennial bunchgrass that grows in the western United States and Canada. It has a deep root system and can tolerate a variety of environmental conditions, making it a popular choice for erosion control, range and pasture improvement, and reclamation projects. Here are some of the propagation methods for Elymus trachycaulus:
Seed Propagation
The most common and reliable method of propagating Elymus trachycaulus is through seed. The seeds can be collected from established plants in the fall or purchased from seed suppliers. The seeds should be planted in the fall or early spring in well-prepared seedbeds. Planting depth should be shallow, about 1/4 to 1/2 inch, and the soil should be kept moist until the seeds germinate, which can take two to four weeks. Seedlings should be thinned to prevent overcrowding and ensure proper growth.
Vegetative Propagation
Vegetative propagation of Elymus trachycaulus is possible through rhizomes or tillers. Rhizomes are underground stems that grow horizontally and produce new shoots and roots. Tillers are new shoots that grow from the base of the parent plant. Both rhizomes and tillers can be dug up and divided into smaller sections for replanting. The new sections should be replanted immediately and kept well-watered until established.
Transplanting
Elymus trachycaulus can also be propagated through transplanting established plants. The best time to transplant is in the fall or early spring when the plants are dormant. The soil should be well-prepared before planting, and the transplants should be planted at the same depth as they were previously growing. Transplanted plants should be watered regularly until established.
Disease Management
Elymus trachycaulus is a relatively disease-resistant plant, but it can still be affected by some diseases. The most common diseases that affect this plant are leaf rust, stripe rust, and stem rust.
Leaf Rust: Leaf rust appears as small, red-brown spots on the leaves, which eventually turn into larger orange or red-brown pustules. This disease can cause premature leaf drop, leading to reduced yields. To manage leaf rust, it is important to remove infected leaves and destroy them immediately. Fungicide applications may also be necessary, especially during the growing season.
Stripe Rust: Stripe rust causes yellow-orange stripes on the leaves. These stripes can eventually become red-brown pustules, similar to leaf rust. Like leaf rust, stripe rust can also be managed through the removal of infected plant material and the use of fungicides.
Stem Rust: Stem rust appears as small pustules on the stems of the plant, turning from a yellowish color to reddish-brown. The disease can lead to stem breakage, which can reduce yields. To manage stem rust, it is best to remove infected stems and destroy them. Fungicide applications may also be necessary to control the spread of the disease.
Pest Management
Although Elymus trachycaulus is not highly susceptible to pests, there are still some pests that can affect the plant.
Armyworms: Armyworms are caterpillars that feed on the leaves of the plant. They can cause significant damage to the plant, leading to reduced yields. To manage armyworms, it is best to use Bacillus thuringiensis or other insecticides that are specifically designed to control caterpillars. It is also important to monitor the field regularly to catch infestations early.
Wireworms: Wireworms are the larvae of click beetles, and they can cause damage to the roots and stems of the plant. They are difficult to control, but there are some preventative measures that can be taken, such as crop rotation and maintaining healthy soil conditions.
Leafhoppers: Leafhoppers are small, winged insects that feed on the sap of the plant. They can cause discoloration and distortion of the leaves, leading to reduced yields. To manage leafhoppers, it is best to use insecticides and maintain healthy soil conditions to encourage natural predators.
Overall, managing pests and disease in Elymus trachycaulus involves a combination of preventative measures and the use of appropriate pesticides or fungicides. Regular monitoring of the field can help catch issues early, and proper sanitation, such as removing infected plant material, can help prevent the spread of disease.
