Fertilization
A light feeding with a balanced fertilizer once a year is recommended for Agropyron boreale (Turcz.) Drobow ex Polunin var. alaskanum (Scribn. & Merr.) Welsh. Springtime is the ideal season for fertilization, as it will give the plant a boost during the growing season. Avoid over-fertilization as it can result in excessive foliage growth at the expense of flowering.
Pruning
Agropyron boreale (Turcz.) Drobow ex Polunin var. alaskanum (Scribn. & Merr.) Welsh does not require significant pruning. However, deadheading spent flowers can prolong flowering time. In late winter or early spring, you can prune out dead or damaged stems to promote new growth in the upcoming growing season. Also, prune out old growth in the center of the plant to encourage new growth and reduce the risk of disease.
Propagation Methods for Agropyron boreale (Turcz.) Drobow ex Polunin var. alaskanum (Scribn. & Merr.) Welsh
Agropyron boreale (Turcz.) Drobow ex Polunin var. alaskanum (Scribn. & Merr.) Welsh, also known as Alaska wheatgrass, can be propagated through either seed or vegetative means.
Propagation through Seed
The easiest and most common method of propagation for Alaska wheatgrass is through seed. The seeds are best collected in late summer when the plant has matured, turned brown, and is easily harvested. The seeds should then be dried, cleaned, and stored in a cool, dry location until they are ready to be planted.
When planting, Alaska wheatgrass seeds should be sown in the fall or early spring when temperatures are cool and moisture levels are optimal. The seeds should be sown in a well-prepared seedbed that has been furrowed or drilled at a depth of 1/4 to 1/2 inches. The seedbed should be kept moist until germination occurs, which typically takes between 10 and 21 days.
Propagation through Vegetative Means
While less common, Alaska wheatgrass can also be propagated through vegetative means. This is typically done through either rhizome or root division.
Rhizome division involves carefully digging up a mature plant and gently separating the rhizomes or underground stems. These rhizomes can then be planted in a prepared seedbed and kept moist until they take root and begin to sprout new growth.
Root division is similar to rhizome division but involves separating the plant's roots instead of the rhizomes. This method can be more challenging because it requires an established plant with well-developed roots. However, it can be an effective way to propagate Alaska wheatgrass in areas where seeds may not be readily available.
Overall, Alaska wheatgrass is a hardy plant that can thrive in a variety of environments and is relatively easy to propagate through both seed and vegetative means.
Disease Management
Agropyron boreale var. alaskanum is generally considered to be a healthy plant with good resistance to most diseases. However, occasional outbreaks of some diseases have been reported, including the following:
- Leaf rust (Puccinia graminis) - The fungus that causes leaf rust can cause yellow-orange spots to form on the leaves of the plant. These spots will eventually turn black and release spores that can spread the disease to other plants in the area. The best way to manage this disease is to remove infected leaves and destroy them. Applying a fungicide may also be effective in controlling the spread of the disease.
- Crown rust (Puccinia coronata) - Crown rust occurs when infected plant debris is left in the field over the winter. In the spring, the fungus can infect new growth. The disease can affect seed production and reduce yield. Crop rotation and plowing fields after harvest may help reduce the incidence of crown rust. Fungicides may also be effective.
Pest Management
Agropyron boreale var. alaskanum is generally not a preferred food source for many common pests. However, some pests may still pose a threat. The following are pests to watch out for:
- Armyworms - Armyworms can consume large amounts of foliage, leaving the plant weak and vulnerable to disease. To manage armyworms, regular scouting and monitoring of fields is recommended. Natural predators like birds and parasitic wasps can help control outbreaks, and if necessary, chemical control methods can be used.
- Cutworms - Cutworms feed on the stems of young plants, often cutting them off at the soil level. To manage cutworms, cutworm collars made of cardboard or plastic can be placed around the base of young plants. The collars act as a physical barrier, preventing cutworms from crawling up the plant stem. Pesticides may also be used to control cutworms if infestations are severe.
- Aphids - Aphids can damage plants by sucking sap from the stems and leaves. They can also transmit plant viruses. To manage aphids, insecticidal soap or oils can be used. Natural predators like ladybugs and lacewings can also help keep aphid populations under control.
