![]() ![]() 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). Description, Honolulu, Hawaii : Hawaii Institute of Tropical Agriculture. Bermudagrass and goosegrass are problem weeds infesting both fairways and greens on many seashore paspalum golf courses. The first step is to correct deficiencies of any element identified in the soil test results. Tropic Shore Seashore Paspalum : Paspalum vaginatum Sw. Seashore paspalum has gained increased popularity in Hawaii due to its salt tolerance and the use of non-potable water on golf courses. 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. ![]()
