Seashore paspalum in hawaii9/12/2023 ![]() This characteristic along with its ability to grow better in shade and survive wet soil make it a better choice than bermudagrass in some environments. Not only can it be irrigated with gray water, but it can survive when irrigated with salt water. This grass has the unique ability to survive in high-salt environments. But it wasn’t used as turf grass until the late 20th century.Īs the need for water conservation increased in many areas, the benefits of using seashore paspalum began to outweigh its disadvantages. It grows naturally in coastal regions throughout subtropical and tropical zones. Seashore paspalum likely originated in the Americas. ![]() Seashore Paspalum Grass Overview Also Known Asīiscuit grass, saltwater couch, silt grass, swamp couch Paspalum vaginatum Seashore Paspalum Grass Lawn Care Calendar.Seashore Paspalum Grass Characteristics.Mowing this grass on the low end of mowing heights will help reduce thatch buildup to a certain degree. NOTE: the extremely low mowing heights require a rotary mowerīoth grasses have thatch, but Seashore Paspalum has a more rapid buildup of thatch and may require verticutting to control this thatch. Seashore Paspalum: 5 - 10 day for optimum growth and appearance at a height of 3/4" Plugs can take up to 5 months for establishment depending on the season planted.Įl Toro: 7 - 14 day for optimum growth and appearance at a height of 1/2" Although available in seed, the preferred method of planting is sod or plugs. Seashore Paspalumīoth popular grasses on the islands feature dense growth, spread by stolons and underground rhizomes. Those grasses include Buffalograss, Bermuda grasses, and Zoysiagrasses.Įl Toro Zoysiagrass vs. Water restrictions are becoming more prevalent on the islands and some thought should be given to installing turfgrasses that have some drought tolerance. Augustinegrass and to a lesser degree Zoysia Japonica. ![]() Grasses well adapted for these conditions include Seashore Paspalum and St. Periodic leaching with fresh water is necessary to flush the salt from the surface soil in these areas. If a shallow salt water table or poor-quality irrigation water is the problem, however, salinity may build up to levels that are higher than even the most tolerant turfgrasses can survive. Fortunately, there are several grasses that have a good degree of tolerance of salinity. Salt tolerance is therefore of great importance in these areas. Many areas in Hawaii are exposed to salt spray, located over shallow water tables with high salt content, or irrigated with brackish water. ![]() Although there are some companies selling Cool-Season turfgrasses that have been specifically adapted for Hawaii's tropical climate- they have not and these grasses will not survive the warm weather. Hawaii lawns are basically Warm-Season turfgrasses. Fertilizer recommendations are given as a part of the soil test report. Soil testing is available from commercial laboratories or the CTAHR Agriculture Diagnostic Service Center at UH-Manoa (beyond Oahu, contact the nearest CTAHR Cooperative Extension Service office). The first step is to correct deficiencies of any element identified in the soil test results. However, N is the most important nutrient for plant growth and therefore must be continually supplied in a turf fertilizer program. Nitrogen (N) is usually not determined in a soil test because most soils are inherently low in nitrogen because it is readily leached through the soil profile. These major elements are essential to normal plant growth and should always be present in adequate amounts. The soil test will show the level of available phosphorus (P), potassium (K), calcium (Ca), and magnesium (Mg). Before starting a turf fertilizer program, a soil test should be done to determine existing fertility and pH levels of the soil. ![]()
