What is the seeding rate for Sea Spray?
Answer: The recommended seeding rate is 0.75 to 1.25 lbs per 1,000 sq ft (3.7-6.1 g/m2) for uncoated seed, and 1 to 2 lbs per 1,000 sq ft (4.9-9.8 g/m2) for Zeba-coated seed.
Can Sea Spray seeded seashore paspalum be overseeded during winter months?
Answer: Yes. Just like bermudagrass, Sea Spray can be overseeded with most cool-season grasses. The transition from one to another is also similar to bermudagrass.
How long until full coverage after germination?
Answer: Typically 8 weeks. While climate and other environmental factors must be taken into account, Sea Spray generally fills in during this timeframe. Results may vary depending on the type of water used.
Does Sea Spray seeded seashore paspalum grow with potable water?
Answer: Yes. As with any other warm-season grass, proper management is the key to success. The emphasis should be on water conservation and responsible irrigation water use. Sea Spray needs to be established with good-quality water. After establishment, Sea Spray thrives on saline water.
How drought tolerant is Sea Spray?
Answer: Very drought tolerant. As long as irrigation scheduling is infrequent and of sufficient duration to promote deep rooting, Sea Spray is better equipped to sustain periods of drought than other varieties. Light, short duration irrigation schedules will keep the roots shallow and will diminish its drought tolerance capability.
Can you actually use ocean water for irrigation?
Answer: Yes, with proper course construction and management of the salts. Is ocean water use recommended? Not if there is any other non-potable water resource.
Can Sea Spray be covered with water and still survive?
Answer: Yes. If floods or storm surges in coastal areas or rising water tables in low areas persist, this grass will survive. It loves low, boggy, "wet-feet" areas. Sea Spray actually has air pockets in the roots that allow it to persist in low oxygen situations.
Does Sea Spray look like bahiagrass (Paspalum notatum) or dallisgrass (Paspalum dilatatum)?
Answer: No. Those two grasses are bunch-types. Sea Spray (Paspalum vaginatum) is a prostrate-growing, rhizomatous, stoloniferous grass that resembles bermudagrass.
What kind of leaf texture does Sea Spray have?
Answer: Sea Spray has a medium-fine leaf texture resembling hybrid bermudagrass. Its nature changes as the mowing height is lowered, transforming from longer internodes and wider leaves during the grow-in phase to very short internodes and smaller, finer leaves when the mowing height reaches 0.125 inches.
What color is Sea Spray?
Answer: Sea Spray is a dark green color, much darker than most bermudas when mowed at the same height. The leaves have a heavy wax load on them that gives it a glistening, shiny green luster. The appearance resembles Kentucky bluegrass and the grass has a similar pattern of striping.
Does Sea Spray get morning dew?
Answer: No. Because of the heavy wax load and lack of leaf hairs, very little moisture accumulates on Sea Spray. Bermudagrass will look white with heavy morning dew, whereas Sea Spray looks bright and shiny.
What is the origin for this seashore paspalum?
Answer: It is native to tropical and sub-tropical regions all over the world. Fine-textured types such as seashore paspalum evolved on sand dunes in South Africa and have been transported to other countries. A secondary center of origin is thought to be the coastal areas of Argentina and Brazil.
Why is seashore paspalum not well known in the turf industry?
Answer: The dominance of bermudagrass and the development of hybrid bermudagrass brought about an increased recognition of turf quality, cosmetic appearance and performance traits among the warm-season grasses. In the 20th century, water was plentiful and fertilizer was cheap. However, the advent of environmental concerns/compliance and water quality/quantity issues are changing the turf industry in the 21st century. Paspalum will be the primary turfgrass to emerge in a new era of environmental stewardship, especially when using non-potable, alternative water resources.
Is this grass species invasive?
Answer: No. Salt tolerant seashore paspalum has been transported to tropical and sub-tropical areas, has persisted for decades in environments favorable for continual growth year-round, and has not proven to be a pest. If this ever happens, herbicides are available to stop its spread into unwanted areas.
Will Sea Spray have a thatch problem?
Answer: As long as nitrogen fertilizer is applied at 4 lbs or less actual N per 1,000 square feet per year and irrigation scheduling is appropriate, thatch build-up will be minimal. Each year, Sea Spray will require one or two verticutting, slicing, and/or aeration events.
