Paspalum vaginatum

Paspalum vaginatum
Seashore Paspalum is a salt-tolerant, warm-season grass widely used on golf courses, sports fields, and lawns in coastal areas. It forms a dense, fine-textured turf and is known for its ability to withstand heavy foot traffic and tolerate low-mowing heights. It spreads via stolons and rhizomes, making it a good choice for erosion control in sandy soils. It is also used in areas with saline water, such as golf courses with recycled water.
CategoryDetails
Plant TypePerennial plant
Estimated Plant Lifespan5 years lifespan
Sun Requirements6+ hours direct sunlight (Full Sun)
Watering Requirements

Method: Deep and infrequent

Frequency: Water deeply when the soil is dry, approximately 1-2 inches below the surface.

Notes: Avoid frequent, shallow watering, which can lead to shallow root systems. The frequency may vary based on climate and soil type. In general, during dry spells, water deeply 1-2 times per week.

Humidity Requirements

Level: Moderate

Maintenance: Generally, it thrives in moderate humidity levels. No specific methods are needed in typical coastal climates.

Temperature Range

Min: -10°C

Max: 40°C

Alternative NamesSaltwater Paspalum
Zoysia japonica
Korean grass
Zoysia japonica
Can be planted together in transition zones, offering similar aesthetic qualities and water needs, and are both tolerant of salt conditions.
Lolium arundinaceum
tall fescue
Lolium arundinaceum
In cooler climates, tall fescue can be mixed with seashore paspalum to improve cold tolerance and overall turf resilience, creating a more adaptable lawn.

Bermudagrass and Seashore Paspalum can compete for resources, especially in terms of sunlight and water in areas where both species are introduced.

Poa annua
Annual Meadow-grass
Poa annua

Annual bluegrass may invade, especially in areas with poor drainage, and compete for nutrients, space, and light, leading to a less uniform appearance.

White grubs

White grubs, the larvae of various beetle species, feed on the roots of Seashore Paspalum. Infestation causes irregular, brown patches in the turf, and the grass is easily pulled up. Damaged roots lead to weakened plants and potential dieback.

Armyworms

Armyworms are caterpillars that consume the blades of grass, leading to large areas of defoliation. The presence of armyworms is often marked by the appearance of tan or brown patches on the lawn, as the grass is chewed down to the soil line.

Steps:

    • Obtain sprigs or sod pieces from an existing, healthy stand of Paspalum vaginatum.
    • Prepare the planting site by removing weeds and debris.
    • Plant sprigs or sod pieces approximately 6-12 inches apart.
    • Water the newly planted grass thoroughly and regularly until established.
    • Keep the soil moist during the establishment period.
    • Choose a healthy stolon from a mature plant.
    • Cut the stolon into segments, each with a few nodes.
    • Prepare a pot or tray with a well-draining potting mix.
    • Plant the stolon segments horizontally, ensuring the nodes are in contact with the soil.
    • Water the segments regularly and keep the soil moist until roots develop.
    • Once the stolons have rooted, transplant them to the desired location.

Neem Oil

Effective against various pests like white grubs and armyworms.

Seaweed extract

Helps stimulate root growth and overall plant health, improving the turf's resilience.

Slow-release Nitrogen Fertilizer

Provides sustained nutrients to the grass, promoting healthy growth and color while minimizing the risk of burning.
