General Appearance
Agropyron subsecundum (Link) A.S. Hitchc. is a perennial grass species that is a member of the Poaceae family. It is commonly known as the 'crested wheatgrass' or 'fairway crested wheatgrass' due to its prominent feature of small crests on the leaves. The plant grows up to 1.2 meters in height, forming dense clumps or tufts that can spread up to 60 centimeters. The leaves tend to be flat, long, and narrow with a dull green color, while the inflorescence consists of spike-like flowers that range from yellow-green to purple in color.
Origin
Agropyron subsecundum (Link) A.S. Hitchc. is native to regions of North America spanning from British Columbia to Manitoba, down to California, and east to the Dakotas. It has also become naturalized across the globe, mostly in regions experiencing arid and semi-arid climates such as the Mediterranean, North Africa, and South Africa. The plant prefers areas with full sun exposure and well-drained soils.
Uses
Agropyron subsecundum (Link) A.S. Hitchc. is widely cultivated and used for its forage and conservation purposes. It is an important forage species for livestock due to its nutrient-rich leaves and high tolerance to grazing and drought. It is often used in range and pasturelands, as well as in the reclamation and restoration of degraded areas such as mine sites and disturbed lands. Additionally, the plant has been used in erosion control and landscaping projects due to its hardiness and ability to stabilize soils.
Overall, Agropyron subsecundum (Link) A.S. Hitchc. is a highly valuable grass species with multiple applications in agriculture, ecology, and environmental management. Its striking appearance and adaptability have made it an attractive option for various purposes.hereLight Requirements
The Agropyron subsecundum plant requires full sunlight exposure to grow properly. Without enough exposure to direct sunlight, the plant's growth and development would be hindered. Therefore, it is advisable to plant this grass in an open area with direct sunlight exposure.
Temperature Requirements
The Agropyron subsecundum grass grows well in a wide range of temperatures. However, the plant thrives best in regions with a medium to high temperature ranging from 70 to 90 degrees Fahrenheit. In areas with low temperatures, the grass may go dormant, but it grows back once the temperature rises.
Soil Requirements
The Agropyron subsecundum plant requires well-draining soil with a good balance of nutrients, moisture, and pH in the range of 6.5 to 8.0. Since this grass species is native to arid and semi-arid regions, it prefers sandy, loamy, and rocky soils. If the soil in the planting area is too moist, it can lead to root rot disease, which can damage or kill the plant.
Cultivation
Agropyron subsecundum requires full sunlight to grow, and it flourishes in well-drained, sandy, or loamy soils. The plant is drought-tolerant and can even grow in areas with low rainfall. The best time to plant Agropyron subsecundum is in early spring when the soil is moist and temperatures are cool.
Watering Needs
During the first growing season, Agropyron subsecundum needs to be watered regularly, but not excessively. Once the plant is established, it can withstand dry conditions and does not require frequent watering. It is critical to avoid overwatering the plant as it can lead to root rot and other diseases.
Fertilization
Agropyron subsecundum is a low-maintenance plant that does not require much fertilization. However, if the soil is extremely poor or lacks nutrients, adding fertilizer can stimulate growth. Ensure to use a balanced fertilizer containing nitrogen, phosphorus, and potassium in equal proportions.
Pruning
Agropyron subsecundum doesn't require much pruning. However, removing dead or damaged leaves helps to keep the plant healthy and tidy. In addition, it is critical to cut back the plant heavily once every three years to rejuvenate it and stimulate new growth.
Propagation of Agropyron subsecundum
Propagation of Agropyron subsecundum can be achieved through both sexual and asexual means.
Sexual propagation
Agropyron subsecundum produces small, inconspicuous flowers that are wind-pollinated. The plant typically blooms from late spring to early summer, producing spike-like inflorescences that are 6-12 inches long. Once the flowers are fertilized, they produce small grains that can be harvested and used for seed propagation. The seeds should be sown in early fall in well-draining soil. Germination can occur after a few weeks, but it may take several months for the seedlings to emerge.
Asexual propagation
Agropyron subsecundum can also be propagated asexually through vegetative means. One common method is through division. As the plant matures, it develops a network of underground rhizomes. Sections of the rhizome can be cut off and replanted elsewhere, providing a new plant that is genetically identical to the parent. This method is typically done in late fall or early spring, when the plant is dormant.
Another asexual propagation method for Agropyron subsecundum is through stem cuttings. Young, healthy stems can be cut and planted in moist soil and kept in a warm environment until they take root. Unlike division, stem cuttings produce a plant that is genetically different from the parent.
Disease Management of Agropyron subsecundum (Link) A.S. Hitchc.
Agropyron subsecundum (Link) A.S. Hitchc., commonly known as creeping wheatgrass, is a hardy grass species that is resistant to many diseases. However, it can still be susceptible to some diseases that can impact its growth and yield.
One of the most common diseases that can affect Agropyron subsecundum is stem rust. The rust causes orange pustules on the stems and can cause the plant to wither and die. To manage this disease, it is recommended to remove and destroy infected plants, limit overhead irrigation, avoid over-fertilization, and use resistant cultivars if possible.
Another disease that can impact Agropyron subsecundum is leaf rust. This disease causes orange pustules on the leaves and can cause premature leaf drop and stunted growth. To manage this disease, it is recommended to remove and destroy infected plants, avoid overhead irrigation, and use resistant cultivars if possible.
Pest Management of Agropyron subsecundum (Link) A.S. Hitchc.
Agropyron subsecundum can also be impacted by pest infestations that can cause damage to the plant. The most common pests that can affect this plant are aphids and grasshoppers.
Aphids are small, soft-bodied insects that feed on the sap of the plant and can cause significant damage if not managed properly. To manage aphids, it is recommended to use insecticidal soaps or oils, attract beneficial insects like ladybugs and lacewings, and employ companion planting strategies.
Grasshoppers are larger insects that can eat the foliage and stems of the plant, causing significant damage to the plant. To manage grasshoppers, it is recommended to use insecticides and repellents, reduce the vegetation around the plant to limit hiding places, and use physical barriers like netting or screens if possible.
