Paspalum Setaceum Michx. Var. Psammophilum (nash) D. Banks - >>paspalum Setaceum

Overview of Paspalum setaceum var. psammophilum

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks, commonly referred to as sand paspalum, is a perennial grass species that belongs to the Poaceae family. This plant is native to the southeastern United States, and it thrives in full sun and sandy soils. It is usually found in coastal sand dunes, and it can tolerate salt spray and poor soil conditions.

Appearance of Paspalum setaceum var. psammophilum

Sand paspalum has a bunching habit and can grow up to 60 cm in height. It forms dense patches because the stems radiate from a central base. The leaves are narrow and can grow up to 15 cm in length. The inflorescence is a spike-like structure that emerges from the central base, and it produces small flowers that are green in color. Fruits are small, oval, and persistent.

Common Names of Paspalum setaceum var. psammophilum

In addition to sand paspalum, this plant is known by several other common names, including seashore paspalum, Gulf paspalum, and inland seashoregrass.

Uses of Paspalum setaceum var. psammophilum

While sand paspalum is not typically grown for forage or ornamental purposes, it is an essential plant in coastal sand dune ecosystems. It helps to stabilize sandy soils, prevents erosion, and provides habitat for wildlife. Additionally, it is a popular turfgrass variety for golf courses and sports fields due to its ability to withstand salt and drought stress.

Light Requirements

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks requires full sun to partial shade exposure to light, especially during its growing season. This plant requires a minimum of six hours of direct sunlight per day to allow for optimal growth and development.

Temperature Requirements

This plant requires moderate to warm temperatures to grow well. The optimal temperature range for Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks growth is typically between 60°F to 85°F. The lowest temperature that this plant can tolerate is around 50°F, while the upper limit is approximately 100°F.

Soil Requirements

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks prefers well-drained soils, such as sandy or loamy soils with a pH between 5.5 and 7.5. This plant also prefers soils that are rich in organic matter, which can help retain moisture and nutrients. In addition, this plant has a high tolerance for drought and salt, making it ideal for growing in coastal regions with sandy soils.

Cultivation methods

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks prefers a well-draining sandy soil with a pH range of 6 to 7.5. It can be propagated by seeds, sods, or plugs. Sow the seeds in a shallow bed and cover them with a thin layer of soil. Keep the soil moist until germination occurs. If using sods or plugs, make sure they are healthy and free from any pests or diseases.

Watering needs

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks is drought-tolerant but requires regular watering to establish a strong root system. Water deeply but infrequently, providing enough water to saturate the soil to a depth of 6 inches. Avoid overwatering, which can lead to root rot and other fungal diseases.

Fertilization

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks benefits from annual fertilization with a balanced fertilizer in early spring. Apply the fertilizer at a rate of 1 pound per 1000 square feet of soil area. Avoid using excessive amounts of fertilizer as this can lead to excessive growth and pest problems.

Pruning

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks does not require extensive pruning but can benefit from light pruning to encourage thicker growth and to remove any damaged or dead foliage. Use gardening shears or a lawnmower to trim the plant to the desired length. Avoid cutting too low, which can damage the roots and lead to stress on the plant.

Propagation of Paspalum setaceum Michx. var. psammophilum

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks, commonly known as sandhill paspalum, is a warm-season perennial grass native to the southeastern United States. It grows well in sandy soils and is a popular turfgrass species used for golf courses, sports fields, and landscapes. The plant can be propagated through several methods, including seed, sod, and stolons.

Seed Propagation

Seed propagation is the most common method used to grow new sandhill paspalum plants. The seeds are typically harvested in the fall and can be planted immediately or stored for later use. To plant the seeds, prepare a seedbed by removing any debris and weeds. Spread the seeds evenly over the bed and cover them with a thin layer of soil. Keep the soil moist until the seeds germinate, which usually takes 7 to 14 days. Once the seedlings are established, they can be transplanted to their permanent location.

Sod Propagation

Sod propagation is a quick and easy way to establish a sandhill paspalum lawn. Sod is sold in rolls or squares and consists of mature grass plants with an established root system. The sod can be cut into small pieces and planted immediately or stored for a short period in a cool, shady area. To plant the sod, prepare the soil by removing any debris and weeds. Lay the sod pieces over the soil, making sure they are tightly pressed against each other. Water the sod thoroughly for the first few days to help it establish roots.

Stolon Propagation

Stolon propagation is another method used to propagate sandhill paspalum. Stolons are horizontal stems that grow above ground and produce new plantlets at each node. To propagate sandhill paspalum using stolons, select healthy, mature plants with well-established stolons. Cut the stolons into small sections, making sure each section has at least one node. Plant the stolon sections in a prepared seedbed and cover them with a thin layer of soil. Keep the soil moist until the stolons have established roots and are growing vigorously.

Overall, sandhill paspalum can be propagated through seed, sod, and stolons. Each method has its advantages and disadvantages, and the choice of method will depend on various factors such as time, cost, and resources available.

Disease Management

Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks is generally a healthy plant that is not prone to diseases. However, there are few diseases that may affect it.

• Leaf spots: These are caused by fungal pathogens and are characterized by small black or brown spots on the leaves. To manage these, remove infected leaves promptly, avoid overhead watering, provide good air circulation, and apply appropriate fungicide.
• Root rot: This is caused by waterlogged soil, which results in the death of roots. To prevent root rot, avoid overwatering, improve soil drainage, and remove infected plants.

Pest Management

While Paspalum setaceum Michx. var. psammophilum (Nash) D. Banks is not highly susceptible to pests, some may still be a concern.

• Armyworms: These are caterpillars that feed on the leaves of the plant, causing significant damage. To manage armyworms, apply appropriate insecticides.
• Cutworms: These are another type of caterpillar that feed on the plant's stems, causing them to wilt and eventually die. To manage cutworms, apply appropriate insecticides.
• Grasshoppers: These feed on the plant's foliage, causing significant damage. To manage grasshoppers, apply appropriate insecticides and remove any nearby grassy areas where the pests may multiply.
• Mites: These are tiny insects that suck the sap from the leaves, causing yellowing and distortion. To manage mites, apply appropriate miticides or insecticides.
