Fertilization Needs for Agropyron caninum ssp. majus
Agropyron caninum ssp. majus grows in a range of soil types, but it benefits from fertile soils. Soil fertility can be increased through the application of nitrogen, phosphorus, and potassium-based fertilizers. The recommended fertilizer application is around 50 to 60 pounds per acre of nitrogen, 30 to 45 pounds per acre of phosphorus, and 70 to 80 pounds per acre of potassium.
The best time to fertilize is during the fall or spring seasons when soil temperatures are cooler. Top dress the soil before planting and then reapply two to three times per year for optimal growth. Fertilizers should be applied evenly across the soil surface and then watered to avoid fertilizer burn.
Pruning for Agropyron caninum ssp. majus
Agropyron caninum ssp. majus does not require pruning as it is a grass species that grows from the base. However, regular mowing can help maintain optimal height and density for high-quality hay or grazing. It also helps remove old and dead leaves, which can accumulate and become a breeding ground for fungal diseases.
The recommended mowing height is around 6 to 10 inches, depending on the intended use of the plant. For hay production, mow at a lower height to promote regrowth, and for grazing purposes, a higher height helps maintain nutrient content and reduce soil compaction.
Propagation of Agropyron caninum (L.) Beauv. ssp. majus (Vasey) C.L. Hitchc.
Agropyron caninum (L.) Beauv. ssp. majus (Vasey) C.L. Hitchc., commonly known as dog wheat, is a perennial grass species. The following are the available propagation methods for this plant:
Seed Propagation
Seed propagation is the most common method of propagating Agropyron caninum. The plant produces viable seeds that can be collected and stored for later use. The seeds have a hard outer layer that needs to be scarified before planting to promote germination. This can be done manually by chipping the seed coat with a knife or by soaking in hot water.
After scarification, the seeds can be sown directly into the soil or started in trays. They should be planted in well-draining soil and kept moist until germination occurs. Once the seedlings have reached a height of 4-6 inches, they can be transplanted to their permanent location.
Vegetative Propagation
Vegetative propagation of Agropyron caninum is possible through division. This method involves separating the plant into smaller sections and replanting. This can be done in the spring or fall when the plant is dormant.
The plant should be dug up and the root system carefully separated into smaller clumps. Each clump should have a healthy root system and several shoots. The smaller sections can then be replanted in a new location.
Cutting Propagation
Agropyron caninum can also be propagated through cuttings. This method involves taking a stem cutting from a healthy plant and rooting it. The cutting should be taken in the spring or early summer when the plant is actively growing.
The cutting should be about 3-4 inches long and contain at least one node. Remove the leaves from the lower half of the stem and plant the cutting in well-draining soil. Keep the soil moist and place the cutting in a shaded area. Once roots have developed, the new plant can be transplanted to a permanent location.
