Permaculture uses
Saint Augustine grass is primarily used as a lawn grass for erosion control and ground cover. It can be used as a mulch in some circumstances. Its dense growth habit suppresses weeds and prevents soil erosion. It's not typically used for food or medicinal purposes, but provides habitat for beneficial insects and other organisms within a permaculture system. Certain cultivars offer different growth habits and tolerances.

A warm-season perennial grass commonly used as turf
Botanical description
Stenotaphrum secundatum is a warm-season perennial grass distinguished by its broad, flat blades and creeping stolons. It grows vigorously, forming a dense turf. Leaves are typically folded in the bud and are obtuse at the tip. The inflorescence is a spike-like raceme partially embedded within the upper leaf sheath. It has a relatively coarse texture compared to other lawn grasses and spreads aggressively. The ligule is a short, fringed membrane. The plant prefers warm, humid climates and is tolerant of shade and saline conditions.
Companion planting
Saint Augustine grass is typically used as a monoculture lawn, and companion planting is not a primary consideration. However, it may compete with other plants for resources. Certain broadleaf weeds are common companions and competitors. When used in permaculture settings, careful placement is needed to prevent it from outcompeting desirable plants. Its dense growth can suppress weeds, but can also inhibit the establishment of other ground covers if not managed.
Propagation methods
Saint Augustine grass is primarily propagated vegetatively through stolon cuttings and plugs. Seed propagation is possible but less common due to low seed viability and variability. Division of established turf is also a viable method for smaller areas.
History and traditions
Saint Augustine grass originated in the coastal regions of the Gulf of Mexico and Africa. It has been cultivated as a lawn grass in many warm climates around the world. Historically, its primary use has been for lawns, pastures, and erosion control. Its quick spreading nature has made it popular for establishing ground cover. While not extensively used in traditional medicine, its ground-covering ability has played a role in preventing soil erosion and maintaining land stability in various cultures.
Usage calendar
Saint Augustine grass actively grows during the warm months (spring, summer, and early fall). Planting is best done in the spring or early summer. Fertilization and irrigation are typically required during the growing season. Pruning or mowing is done regularly to maintain desired height. Dormancy occurs during the winter months.
