Saltmeadow cordgrass is a tall thin grass that grows naturally along the eastern and southern shoreline of North and South America. It has been used to stop sand bank erosion in several parts of the United States along with Saltwater cordgrass and American beach grass. Although it can withstand inundation of saltwater for short periods, this grass is normally grown at mean tide level or above. The seed is feed for many birds and it provides shelter to other shore and marsh type animals.
Plant seeds in peat pots. Use at least six to eight seeds per pot. You will need one pot every 12 to 18 inches in rows about 3 feet apart. Start to measure from mean high-tide line up the shore for the area that you want to sow to figure out how many peat pots you will need. Start them in early March for a May planting.
Water to keep the peat pots moist and place them where they will get at least four to six hours of sun a day. Weed out to the three to five strongest plants per pot. Keep the plants at a temperature of at least 60 degrees.
Plant peat pots containing the three to five culms per pot of grass in late spring. The plants should be about a foot tall for planting. Dig a hole in the sandy soil to accommodate the peat pot, place the roots in the hole and press the soil tightly around the roots.
Dig a small hole next to each planting and fill with about 2 oz. of either a 10-10-10 fertilizer or a slow release fertilizer like Osmocote, which is preferred. Fertilize again in a year.
Monitor plants for any that are not surviving. If they are destroyed or die, they should be replaced right away. If any debris washes up around the grass, it should be removed immediately.
