Title: When to plant grasses on Long Island, NY
Answered by: Nan Hampton
It probably won't hurt to sow your grass seeds now, but they will most likely lie dormant and not germinate until the onset of the warm spring rains. Sea Grant New York and Cornell Cooperative Extension of Suffolk County has an excellent article that recommends planting native grasses in the spring. Indeed, Cornell University and St. Lawrence County Extension recommend sowing switchgrass (Panicum virgatum) when the soil temperature has reached 60° F in the spring. Generally, seeds do well if they are sown when they would fall naturally from the plant. For most of the species listed below that would have been late summer or early fall. However, at least some of those seeds that naturally fall from the plants no doubt become food for small rodents and birds. So, your best bet for commercially purchased seeds, it would seem, is to sow them in the spring when they have a chance to germinate quickly.
It sounds as if you need to consider grasses with some salt tolerance. New York City Department of Parks & Recreation lists the following grasses as salt tolerant:
Ammophila breviligulata (American beachgrass)
Distichlis spicata (saltgrass) and here are photos and more information
Panicum amarum (bitter panicgrass) and here are photos
Spartina alterniflora (smooth cordgrass)
Spartina patens (saltmeadow cordgrass) and here are photos and more information
Spartina pectinata (prairie cordgrass)
Panicum virgatum (switchgrass) moderately salt tolerant
Schizachyrium scoparium (little bluestem)
Not on their list:
Andropogon gerardii (big bluestem) moderately salt tolerant
Andropogon virginicus (broomsedge bluestem) salt tolerant
Deschampsia cespitosa salt tolerant
Sorghastrum nutans (Indiangrass) is on the Native Plant Society of New Jersey's List of Coastal Plants—Salt Tolerant.
