Trisetum spicatum var. molle, also known as Soft False Oatgrass, is a perennial plant that belongs to the Poaceae family. It is a native plant of North America and can be found in various habitats, including open forests, meadows, and wetlands.
General Appearance
Soft False Oatgrass grows up to 1-3 feet tall and exhibits a bunching or tufting growth habit. The plant bears slender, upright stems with leaf blades that are linear, flat, and bright green in color.
The leaves of Trisetum spicatum var. molle are soft and hairless, with a texture that is comparable to velvet or suede. The plant's inflorescence features narrow and spiky flower heads that taper to a point. The flowering period of this plant occurs in the late spring and early summer.
Common Names
Trisetum spicatum var. molle is commonly known as Soft False Oatgrass, Velvet Grass, and Soft Trisetum.
Uses
Soft False Oatgrass is commonly used for erosion control, habitat restoration, and soil stabilization. This plant is also used as a forage grass for livestock, particularly sheep and cattle. The soft leaves of Trisetum spicatum var. molle make it an excellent food source for animals.
Additionally, some Indigenous North American cultures have used Soft False Oatgrass for medicinal purposes, including the treatment of diarrhea and other gastrointestinal ailments.
Light Requirements
Trisetum spicatum var. molle is a shade-tolerant plant that can grow well in low to high light conditions. Generally, it thrives in partial shade to full sun, with a preference for partially shaded areas.
Temperature Requirements
This plant species can thrive in a variety of temperature zones, from cool to warm climates. It is hardy in zones 3-8 and is commonly found in mountainous regions with cooler temperatures.
Soil Requirements
Trisetum spicatum var. molle prefers well-draining soils that are rich in organic matter. It can tolerate acidic to neutral soil pH levels, typically ranging from 4.5-7.5. This plant can grow in a variety of soil textures, from sandy loam to clay loam.
Cultivation methods
Trisetum spicatum (L.) Richter var. molle (Kunth) Beal, commonly known as soft spike trisetum, is a cool-season grass that prefers full sun to partial shade and moist soil. It is easy to grow by seed or from divisions in USDA plant hardiness zones 4 to 9. The planting method is to use a seed drill or broadcast the seeds over the prepared seedbed and gently rake them into the soil surface.
Watering needs
Soft spike trisetum requires regular watering during the growing season to keep the soil continuously moist. It cannot tolerate drought conditions, so a consistent water supply is necessary for proper development. It is best to water early in the day to allow the leaves to dry off before evening to reduce the likelihood of fungal growth.
Fertilization
Fertilizing soft spike trisetum is generally not necessary if it is grown in fertile soil. However, if you notice weak or slow growth, you may apply a slow-release nitrogen fertilizer in early spring. Avoid over-fertilizing as this may cause the grass to produce excessive foliage and reduce stress tolerance.
Pruning
Soft spike trisetum does not need frequent pruning. To maintain its shape and vigor, you may prune it once a year in early spring before new growth emerges. Use a sharp pair of shears to remove dead, diseased, or damaged leaves, and cut the remaining foliage down to about 2–3 inches above the ground. This will stimulate the growth of new leaves and encourage denser growth.
Propagation Methods of Trisetum spicatum (L.) Richter var. molle (Kunth) Beal
Trisetum spicatum (L.) Richter var. molle (Kunth) Beal, commonly known as spike trisetum or rough trisetum, is a cool-season perennial grass that is native to North America. It is a valuable forage crop for livestock and wildlife, and is also used for erosion control, reclamation, and ornamental purposes.
There are both sexual and asexual methods for propagating Trisetum spicatum, including seed propagation and vegetative propagation techniques.
Seed Propagation
Seed propagation is the most common method for propagating Trisetum spicatum. The plant produces viable seeds that can be harvested, stored, and sown to produce new plants. The seeds should be harvested when they are fully mature, and then stored in a cool, dry place until they are ready to be sown. The seeds can be sown directly into the soil in the spring or fall, or they can be started indoors and then transplanted once they have reached a suitable size.
Vegetative Propagation
Vegetative propagation can be used to reproduce Trisetum spicatum without the use of seeds. This method is often used to produce more plants that are genetically identical to a desirable parent plant. Vegetative propagation techniques include dividing the plant, taking cuttings, and tissue culture.
Dividing the plant involves digging up the parent plant and separating it into smaller sections, each with its own roots and shoots. The sections can then be replanted to produce new plants.
Another method of vegetative propagation is taking cuttings from the parent plant. Cuttings should be taken from the healthiest part of the plant and should include a small section of stem and leaves. The cutting should be planted in a suitable rooting medium, such as sand or vermiculite, and kept moist until it has developed roots and can be transplanted to a larger container or the ground.
Tissue culture involves taking a small piece of plant tissue and placing it in a nutrient-rich medium to grow into a new plant. This method is commonly used to produce large numbers of identical plants in a laboratory setting.
Overall, Trisetum spicatum can be propagated using a variety of techniques, both sexual and asexual. Growers can choose the best method for their specific needs and situation.
Disease Management
The plant Trisetum spicatum var. molle can be affected by several diseases that can cause damage to the plant. The most common diseases affecting this plant are leaf spot, powdery mildew, and rust. Leaf spot and powdery mildew are fungal diseases, while rust is caused by a bacteria-like organism called a phytoplasma.
Leaf Spot
Leaf spot is characterized by small, circular, brownish spots on the leaves that can later coalesce into large patches of dead tissue. To manage leaf spot, remove and destroy infected plant material, avoid overhead watering, and apply a fungicide according to the manufacturer's instructions.
Powdery Mildew
Powdery mildew is a fungal disease that appears as a white, powdery coating on the leaves. Plants growing in humid environments with poor air circulation are most susceptible. To manage powdery mildew, remove and destroy infected plant material, increase air circulation, and apply a fungicide according to the manufacturer's instructions.
Rust
Rust is a bacterial disease characterized by yellow to orange pustules on the leaves, stems, and seeds of the plant. The infected parts become brittle and break easily. To manage rust, remove and destroy infected plant material, avoid overhead watering, and apply a copper-based fungicide according to the manufacturer's instructions.
Pest Management
The plant Trisetum spicatum var. molle can also be affected by several pests that can cause damage to the plant. The most common pests affecting this plant are aphids, grasshoppers, and cutworms.
Aphids
Aphids are small, soft-bodied insects that suck sap from the plant, causing yellowing and curling of leaves. To manage aphids, spray plants with a strong stream of water to knock them off, release natural predators like ladybugs, or apply an insecticidal soap or oil according to the manufacturer's instructions.
Grasshoppers
Grasshoppers are large, hopping insects that can cause significant damage by feeding on the plant's leaves and stems. To manage grasshoppers, use physical barriers like mesh or netting, release natural predators like birds, or use an insecticide specifically labeled for grasshopper control.
Cutworms
Cutworms are caterpillars that feed on the stems of young seedlings, causing them to wilt and die. To manage cutworms, use physical barriers like collars made of cardboard or plastic around young plants, release natural predators like parasitic wasps, or apply an insecticide specifically labeled for cutworm control.
