Similar to the Bermuda grasses in texture and playability, Salam Seashore Paspalum was originally marketed for golf greens and tees, especially in salt-challenged environments. Salam Seashore Paspalum is a warm-season perennial grass that spreads by stolons. The stolons and leaves of Salam Seashore Paspalum are slightly coarser than those of common Bermuda grass. However, when mowed regularly at heights of 1 inch or less, the grass produces a dense turf. One of the outstanding characteristics of Salam Seashore Paspalum is its tolerance to saline soils. It is reported to tolerate brackish sites much better than Bermuda grass. Salam Seashore Paspalum grass thrives in moist sites. It tolerates wet conditions much better than Bermuda grass. Although Salam Seashore Paspalum survives prolonged dry periods, it shows moisture before Bermuda grass. Salam Seashore Paspalum’s drought tolerance is similar to that of Centipede grass.
Light, frequent watering is necessary during the establishment of Salam Seashore Paspalum. As the lawn becomes established, less frequent, but longer watering encourages deeper rooting. Salty or recycled water can be used to water Salam Seashore Paspalum. Irrigate established Salam Seashore Paspalum to a soil depth of 4-6 inches at each watering. The duration and frequency of irrigation will vary with soil type. For example, sand requires a shorter period to wet to a 6-inch soil depth, but watering must be more frequent because sand does not hold moisture well. Avoid light, shallow watering, as this will promote shallow rooting.
Mow Salam Seashore Paspalum with a reel mower to a height of 0.5-1 inch for highest quality. If mown too high, the turf will scalp easily and develop a significant thatch problem. A rotary mower may be used, but thatch develops quicker because rotary mowers cannot cut at a height of 1 inch or less. Salam Seashore Paspalum can be an aggressive grass under high fertilizer regimes. Mow once per week or often enough so as not to remove more than 1/3 of the leaf blade per mowing.
Once the Salam Seashore Paspalum grass has completely covered an area, weed invasion is minimal if the lawn is maintained properly. It is important to keep the lawn free of weeds from the time of establishment because few herbicides are registered for use on Salam Seashore Paspalum. This can be done by hand-pulling weeds or by using a reemergence herbicide. Salam Seashore Paspalum is sensitive to many herbicides commonly used on other turfgrasses in Hawaii. A fungus disease has been observed on Salam Seashore Paspalum in Hawaii, but this problem presents itself mostly when the grass is under stress. Proper fertilization, watering, and cultural practice minimize the effects of this fungus disease on Salam Seashore Paspalum.
Salam Seashore Paspalum responds well to fertilizer, but excessive growth and thatch occur with high rates of nitrogen—especially in the summer months. Apply ½ lb of nitrogen fertilizer per 1000 square feet each month as a complete fertilizer or as nitrogen alone, depending on soil test results. On coarse, sandy soils or highly maintained turfs, up to 1 lb of nitrogen per 1000 square feet each month may be necessary. Lower rates may be applied during the winter months (November-February) when growth is slowed. Salam Seashore Paspalum will respond well to iron application when grown in alkaline soils.
