In general, P. urvillei requires moderate fertilization in the spring and fall when the grass is actively growing. However, excessive fertilizer application can lead to unwanted growth and can make the grass susceptible to pests and diseases. It is recommended to conduct a soil test to determine the exact fertilizer requirements of the grass.
Pruning for Paspalum urvillei Steud.
Pruning is not required for P. urvillei unless the grass is used for turf or landscaping purposes. In such cases, regular mowing helps maintain the desired height and promotes new growth. The ideal height for P. urvillei is 2-4 inches, and it is best to leave the clippings on the grass to provide natural fertilization.
It is recommended to sharpen the mower blades regularly to prevent tearing of the grass blades. Additionally, removing no more than one-third of the grass blade during each mowing session helps maintain the health and growth of P. urvillei.
Propagation of Paspalum urvillei Steud.
Paspalum urvillei Steud. is a perennial grass that can be propagated through multiple methods:
Seed propagation
Seeds of P. urvillei can be collected from mature plants during the flowering season. Germination rates can be improved by soaking the seeds in water for 24 hours before planting. The seeds should be planted in well-drained soil in full sun. Seedlings can be transplanted once they have developed into strong plants.
Vegetative propagation
P. urvillei can also be propagated through vegetative means, including stolons and rhizomes. Stolons are above-ground stems that grow horizontally along the soil surface and produce new plants where they make contact with the soil. Rhizomes are underground stems that also produce new shoots and roots. Vegetative propagation is useful for creating new plants that genetically match the parent plant.
Tissue culture propagation
Tissue culture is a method of propagation that involves taking small pieces of plant tissue and placing them in a nutrient-rich medium for growth. This method can be used to propagate specific plant traits, such as disease resistance.
Overall, P. urvillei can be propagated through multiple methods, providing flexibility depending on the needs of the cultivator or gardener.
