Cultivation Details

Sporobolus alterniflorus is very tolerant of climate, being found from the cold temperate regions of northeastern Canada through to the tropical regions of S. America. It does, however, need to be by the coast and grows best when in the intertidal zone[

Requires a sunny position. The plant is adapted to a wide range of soils from coarse sands to clays and mucks. Plant
establishment and productivity appear to be superior on heavier mineral soils such as mucky clays, silty clays, silty clay loams, and fine sands. Soils with very high levels of organic matter pose structural problems and have proven to be problematic in establishing the plant[

Agroforestry Uses:

The plant is used primarily for erosion control along shorelines, canal banks, levees, and other areas of soil-water interface, where it has been proven to provide significant erosion protection. In addition, it is an effective soil stabilizer used on interior tidal mudflats, dredge-fill sites, and other areas of loose and unconsolidated soils associated with marsh restoration. When established in conjunction with shorelines, it provides an effective buffer that dissipates energy, reduces shoreline scouring, and traps suspended sediments and other solids. Dense stands are efficient users of available nutrients, producing significant amounts of organic matter. The cumulative effects of organic matter production, sediment trapping, and erosion control not only provide shoreline protection but also accelerate sediment accumulation and near-shore building. Consequently, this species is a sustainable and renewable restoration resource, and when properly established and in the appropriate habitat, will persist and potentially remain effective indefinitely[

Propagation

Seed - requires light for germination. Seed is generally of low vigour - sow in a greenhouse in spring and only just cover the seed. Germination should take place within 2 weeks. Prick out the seedlings into individual pots when they are large enough to handle. Plant out in the summer if sufficient growth has been made, otherwise overwinter them in a cold frame and plant them out in the following spring.
Division in spring. Very easy, it can also be carried out at other times of year, the divisions being planted direct into their permanent positions.
