Key rule: the closer to salt spray, the more salt-tolerant your plant selection must be. Plants 100+ feet from the water have more flexibility.
Key principles for beach property landscaping: (1) Create windbreak with salt-tolerant hedges (bayberry, rugosa rose, inkberry) before planting tender species behind; (2) Use native coastal plants — they evolved for the conditions; (3) Install gravel or decomposed granite instead of mulch near the dunes — wood mulch blows; (4) Anchor slopes with deep-rooting native grasses; (5) Avoid plants that require regular watering — coastal gardens should be near self-sufficient; (6) Check local regulations for dune disturbance, erosion control, and setbacks.
Best grasses for coastal/ocean properties: American beach grass (Ammophila breviligulata) — best for actual dunes; Sea oats (Uniola paniculata) — zones 7–10, protected in some states; Blue oat grass (Helictotrichon) — ornamental, zones 4–9; Switchgrass (Panicum virgatum) — native prairie grass, excellent salt tolerance; Little bluestem (Schizachyrium scoparium) — bronze fall color, native; Pennisetum alopecuroides — ornamental fountain grass; Sesleria (moor grass) — shade-tolerant coastal grass.
Protect plants from salt spray: (1) Plant in winter when salt spray is highest — spring planting gives establishment time; (2) Use physical windbreaks (fence, hedge) to reduce salt loading on tender plants; (3) Rinse foliage with fresh water after major storms; (4) Choose proven salt-tolerant species for zones closest to water; (5) Apply antidesiccant spray (Wilt-Pruf) to evergreens before winter in heavy spray zones; (6) Raise soil organic matter — salt damage is worse in poor soils; (7) Avoid applying salt-based ice melts near ocean garden areas.
Budget coastal landscaping: (1) Propagate rugosa roses from cuttings — they root easily from softwood cuttings; (2) Collect and direct-sow native seed (sea thrift, beach grass, seaside daisy); (3) Use gravel or shell mulch instead of wood mulch — longer lasting, no blowing; (4) Plant native coastal grasses from plugs ($1–3 each) instead of pots; (5) Salvage driftwood for free focal points and edging; (6) Focus investment on a windbreak hedge first — it enables everything else; Total budget transformation: $500–$2,000 for a typical coastal cottage front yard.
Lakefront landscaping differs from ocean coast: lower salt, but often wind + erosion challenges. Best lake landscaping: Native shoreline buffer (sedges, rushes, native wildflowers) within 10–35 feet of water per most state regulations; Ornamental grasses as informal screening (switchgrass, Karl Foerster); Native shrubs (inkberry, buttonbush, native willows) for shoreline stabilization; Rain garden between lawn and lake to filter runoff; Avoid fertilizers and herbicides within 50 feet of water (many states regulate this); Limestone or fieldstone retaining walls where erosion is active.
