Overview
Poa secunda var. elongate, also known as Elongate Bluegrass or Sandberg Bluegrass, is a perennial grass species belonging to the Poaceae family. The grass is native to North America and can be found in a variety of regions, including the western United States, Alaska, and Canada.
Appearance
The plant grows in clumps and is characterized by its narrow bluish-green leaves that are flat or rolled and have a smooth texture. The grass can grow to a height of up to 18 inches and produces a slender stem that is topped with a spike-like panicle containing small flowers.
Uses
As a native grass to the North American continent, Poa secunda var. elongate has a variety of uses. Historically, indigenous peoples have used the plant's leaves to create baskets, mats, and other woven goods. The grass also plays a crucial role in land restoration projects and erosion control measures. Additionally, some grazing animals feed on the plant, and it can be used as a forage crop or in hay production. The plant has minimal forage value, however, due to its low palatability.
Moreover, the plant is also useful in landscaping applications, especially in areas where adequate water is not available. The grass has the ability to tolerate drought, salt, and poor soil conditions, making it an excellent option for xeriscaping.
In modern medicine, the grass has been used in traditional remedies for treating various health issues such as headache, fever, colds, coughs, diarrhea, and dysentery.
Overall, Poa secunda var. elongate is a versatile plant with several benefits to offer, both culturally and practically. Its resilience and ability to survive in harsh environments make it a valuable asset to countless industries that rely on sustainable resource management.
Growth Conditions for Poa secunda J. Presl var. elongata (Vasey) Dorn
Light: Poa secunda J. Presl var. elongata (Vasey) Dorn typically thrives in full sun to partial shade. It can tolerate some shade but may not grow as vigorously as it would in full sun. In its natural habitat, it grows in fields, meadows, and open woods.
Temperature: This plant is adapted to a range of temperatures, from cool to warm. It is native to North America and can be found growing in areas with wide temperature fluctuations, such as the Great Plains and Rocky Mountains. Poa secunda J. Presl var. elongata (Vasey) Dorn can tolerate cold winter temperatures and hot, dry summers, and can even tolerate occasional wildfires.
Soil: Poa secunda J. Presl var. elongata (Vasey) Dorn grows best in well-drained soils, but can also tolerate soils with poor drainage. It prefers soils that are sandy, gravelly, or rocky, and can grow in soils that are low in organic matter. It is also tolerant of alkaline soils. However, it may not grow well in soils that are too moist or compacted.
Cultivation Methods
Poa secunda var. elongata is a hardy plant that is easy to grow and maintain. It can be propagated from seed or by dividing existing clumps in early spring or autumn. The plant prefers well-drained soil with a slightly acidic pH, and it thrives in full sun or partial shade. It can tolerate drought and harsh environmental conditions, making it a great addition to xeriscapes or rock gardens.
Watering Needs
Although Poa secunda var. elongata is drought-tolerant, it needs regular watering during the growing season to maintain its greenery and vigor. Water the plant deeply once or twice a week depending on the soil's moisture level, and avoid overwatering which can lead to root rot. During the winter, reduce watering to once every two weeks.
Fertilization
Poa secunda var. elongata rarely needs fertilization, but it can benefit from a light dose of slow-release nitrogen-based fertilizer in early spring when the plant is beginning to grow. Avoid using fertilizers high in phosphorus and potassium, which can harm the plant. Mulching the plant with organic matter during the growing season can also provide it with the necessary nutrients.
Pruning
Poa secunda var. elongata does not require intense pruning but can benefit from occasional removal of dead or damaged foliage and seed heads to encourage new growth and improve its appearance. Use a pair of sharp pruning shears and cut back stems to the ground level or just above the base. Do not prune the plant during its dormant season.
Propagation of Poa secunda J. Presl var. elongata (Vasey) Dorn
Poa secunda J. Presl var. elongata (Vasey) Dorn, commonly known as Sandberg bluegrass, can be propagated through various methods including seeds, sod, and plugs.
Seed propagation
Seed propagation is the most common method used for Sandberg bluegrass. Collect the seeds from the plant when they ripen and sow them in a prepared bed during fall. Ensure the soil is well-drained and free from weeds and debris. The seedlings will emerge in spring and begin to establish.
Sod propagation
Sod propagation involves planting pre-grown grass squares. In this method, lay the sods on a prepared bed, ensuring the edges are tightly packed to inhibit weed growth. Water regularly to ensure the roots establish in the soil. Sodding can be done during any of the growing seasons, although they establish better and faster during rainy seasons.
Plugs propagation
Plugging involves planting small square grass plugs into the soil, allowing them to establish and grow to form a new lawn. To propagate Sandberg bluegrass in this method, dig small holes and plant the plugs at a distance of 6 to 12 inches from each other. Water the plugs immediately and regularly until they establish.
Propagation of Sandberg bluegrass is relatively easy, and any of these methods can be used. Ensure the growing conditions are favorable to give the plant a better chance of propagation and establishment.
Disease management
Poa secunda J. Presl var. elongata (Vasey) Dorn is relatively disease-resistant. However, several diseases can affect the plant, including:
- Snow molds: These are a common problem in areas with prolonged snow cover. They can cause yellowing and death of the leaves. To prevent snow molds, avoid over-fertilizing the lawn, remove excessive thatch, and avoid early fall fertilization.
- Fusarium patch: This disease is prevalent in cool, moist environments and attacks the base of the crowns of grass plants, causing them to turn brown and die. To prevent fusarium patch, avoid excessive nitrogen fertilization, ensure adequate soil drainage, and mow the lawn regularly.
- Rust: This disease is characterized by yellow to brownish-orange spots on the leaves. To prevent rust, ensure adequate soil drainage, avoid excessive nitrogen fertilization, and mow the lawn regularly.
Pest management
While pests are not as common a problem as diseases in Poa secunda J. Presl var. elongata (Vasey) Dorn, some insects may cause damage to the plant. Here are some common pests:
- Chinch bugs: These insects are most active in hot, dry weather and can cause spots of yellowing on the leaves. To control chinch bugs, introduce predators such as ladybugs or lacewings, or apply insecticidal soap or neem oil.
- Sod webworms: These are the larvae of lawn moths and can cause brown patches on the lawn. To control sod webworms, introduce predators such as wasps or birds, or apply Bacillus thuringiensis var. kurstaki, which is an effective biological control agent.
- Armyworms: These insects feed on the grass blades and can cause brown patches on the lawn. To control armyworms, introduce predators such as birds or parasitic wasps, or apply insecticides such as acephate or spinosad.
