■^ Early spring Is best when temperatures are below 15° Celsius. 



^Ground should be cool and wet. 



Seeding is practical only when protection can be provided from eroding 

 and drying winds by mulching or frequent irrigation, and is therefore not 

 applicable to most beach areas. Beach-grass seeds are not generally available 

 from commercial sources, and must be wild harvested during the fall for spring 

 seeding. 



Where field tested, beach grasses have responded to supplemental 

 nutrients by increased foliage production. This in turn provides greater 

 sand-trapping capacity. Rates of fertilizer are provided in Table 6-4. Only 

 American beachgrass should be routinely fertilized the second growing season 

 with 56 kilograms per hectare (50 pounds per acre) of fertilizer (nitrogen) in 

 April and again in September. Other species should be fertilized if overall
