Overview:
Elymus trachycaulus (Link) Gould ex Shinners ssp. teslinensis (Porsild & Senn) A. Löve, commonly known as Teslin wheatgrass, is a subspecies of Elymus trachycaulus, a species within the Poaceae family. It is a native grass species found in Arctic and subarctic regions of North America.
Origin:
The Teslin wheatgrass subspecies is native to the northern regions of North America and is commonly found in Alaska and Canada.
Common Names:
The most common name for Elymus trachycaulus ssp. teslinensis is Teslin wheatgrass. It is also called Teslin grass, as well as Arctic wheatgrass (although this name is also used to refer to the species as a whole).
Appearance:
Teslin wheatgrass typically grows in small clumps and has rigid leaves that are about 5-10 cm long and 2-4 mm wide. The plant's inflorescence is typically a dense spike-like panicle that can grow up to 20 cm tall. In general, Teslin wheatgrass is a hardy, non-rhizomatous plant that is adapted to cold, dry climates.
Uses:
Teslin wheatgrass has a variety of uses, primarily as a forage crop for livestock. The plant's hardiness makes it ideal for cold climates and it is often used to revegetate disturbed land and prevent soil erosion. It is also an important food source for many indigenous communities in the northern regions of North America. In addition, the plant has been studied for its potential as a biofuel crop due to its high biomass production and hardiness.

Cultivation Methods for Elymus trachycaulus ssp. teslinensis
Elymus trachycaulus ssp. teslinensis, commonly known as slender wheatgrass, is a perennial bunchgrass found in North America. Here are some cultivation methods that can help you grow healthy Elymus trachycaulus ssp. teslinensis plants:
- Elymus trachycaulus ssp. teslinensis grows best in full sun but can tolerate some shade.
- The ideal soil pH range for growing Elymus trachycaulus ssp. teslinensis is between 6.0 and 8.0.
- Ensure that the soil is well-draining and not waterlogged.
- Prepare the planting area by removing any weeds, rocks, or debris.
- Sow the seeds at a depth of approximately ¼ inch and cover lightly with soil.
- Water the seeds thoroughly after planting and keep the soil moist until the seeds germinate.
Watering Needs for Elymus trachycaulus ssp. teslinensis
Elymus trachycaulus ssp. teslinensis requires regular watering, especially during its initial growth period. Below are some watering tips:
- Water the plants deeply, and avoid overwatering, as this can lead to root rot.
- During hot and dry periods, water the plants at least once a week, ensuring that the soil is moist to a depth of at least 6 inches.
- If possible, water the plants in the morning or evening to reduce water loss from evaporation.
Fertilization for Elymus trachycaulus ssp. teslinensis
Fertilization can help boost the growth and health of Elymus trachycaulus ssp. teslinensis. Here are some fertilization tips:
- Apply a slow-release, nitrogen-rich fertilizer in mid-spring, before the plant enters its active growing season.
- If the plants show signs of deficiency, such as yellowing of leaves, apply a quick-release, nitrogen-rich fertilizer.
- Water the plants after fertilization to ensure that the nutrients are absorbed effectively.
Pruning for Elymus trachycaulus ssp. teslinensis
Elymus trachycaulus ssp. teslinensis does not require much pruning, but removing old and dead plant debris can help promote new growth. Here are some pruning tips:
- In late fall or early spring, remove any dead or damaged stems and leaves to prevent disease and pest infestations.
- Cut back any overgrown stems by one-third of their length to promote bushier growth.
- Avoid pruning the plants during the active growing season, as this can stress the plants and reduce their growth potential.
Propagation of Elymus trachycaulus ssp. teslinensis
Elymus trachycaulus ssp. teslinensis, commonly known as Teslin wheatgrass, is a cool-season perennial grass species native to dry slopes, sandbars, and hillsides of North America. The species is highly valued for its extended growing season, drought tolerance, and versatility in soil types. Propagation of Elymus trachycaulus ssp. teslinensis can be achieved through various methods including:
Seed Propagation
Seed propagation is the most common method used to propagate Elymus trachycaulus ssp. teslinensis. Seeds should be collected from fully mature plants during the fall season. The collected seeds should be cleaned, treated with fungicide, and stored in a cool and dry place until the next growing season. In the spring, the seeds can be sown directly into moist and fertile soil. The soil should be kept consistently moist until the seedlings reach a height of 2-3 inches.
Division Propagation
Division is also an effective method for propagating Elymus trachycaulus ssp. teslinensis. Division should be done in the spring or fall while the plant is dormant. Carefully dig up the plant, and divide it into smaller sections with a sharp knife or shovel. Each section should have a viable root system and several healthy shoots. The divided sections can then be replanted in the desired location with well-drained and fertile soil. Water the replanted sections adequately until they are established.
Vegetative Propagation
Vegetative propagation is another method used to propagate Elymus trachycaulus ssp. teslinensis. The plant can be propagated through vegetative cuttings or tissue culture. Propagation through vegetative cuttings involves taking stem cuttings from healthy plants, dipping them into a rooting hormone, and planting them into a soilless mix. The cutting should be kept consistently moist until roots develop. Propagation through tissue culture involves growing plant cells or tissues in a sterile environment under controlled conditions.
Propagation of Elymus trachycaulus ssp. teslinensis can be achieved through various methods depending on the availability of materials and resources. Each method has its advantages and disadvantages, but all should result in healthy and robust seedlings or plants.
Disease Management
Elymus trachycaulus ssp. teslinensis, like all plants, is susceptible to diseases caused by bacteria, fungi, and viruses. One of the most common diseases that affect this plant is stem rust, which causes brown or reddish patches on the stem. To manage this disease, it is essential to remove and destroy any infected plant parts and to apply a fungicide to the remaining plant parts. Preventive measures such as planting rust-resistant cultivars and avoiding overcrowding can also help reduce the incidence of stem rust.
Another disease that affects Elymus trachycaulus ssp. teslinensis is leaf smut, which causes dark streaks or spots on the leaves. To manage this disease, it is important to remove and destroy any infected plant parts and to spray the plant with a fungicide. Additionally, planting resistant cultivars and avoiding moist environments can help prevent leaf smut.
Pest Management
Elymus trachycaulus ssp. teslinensis is also susceptible to damage caused by pests such as grasshoppers, mites, and aphids. Grasshoppers can cause significant damage by chewing on the stem and leaves of the plant. To manage grasshopper populations, it is recommended to use insecticides and to introduce natural predators such as birds, praying mantis, and ladybugs to the environment.
Mites can cause damage by sucking sap from the plant, which results in discoloration and deformation of the leaves. To manage mite populations, it is important to apply miticides to the plant and to prune and dispose of any severely affected plant parts.
Aphids can also cause damage by sucking sap from the plant. Additionally, they leave a sticky residue on the plant, which can promote the growth of fungi. To manage aphid populations, it is essential to introduce natural predators such as ladybugs and lacewings and to spray the plant with insecticides.
