For homes near the sea, divide the garden into exposed and sheltered zones, put salt-tolerant plants such as screw pine, beach naupaka, beach morning glory or Manila grass on the exposed side, improve sandy soil with organic matter and mulch, and use marine-grade stainless steel or rust-free materials.
Salt travels on the wind, not only in the soil
Scorched leaf edges and dry tips on the sea-facing side are usually caused by wind-borne salt spray. Beachfront homes in Bang Saen, Pattaya, Jomtien and Rayong receive far more than homes a few hundred metres inland. Before choosing plants, observe seasonal wind direction, salt marks on glass and which existing plants nearby stay healthy.
Plan the garden in three layers
- Front layer: highly salt-tolerant plants that shelter the rest
- Middle layer: shrubs and feature trees with moderate sun and wind tolerance
- Back layer: thin-leaved or flowering plants that need shelter, near the house or walls
A good windbreak lets some air through rather than being a solid wall, which can create turbulence that drops hard behind it.
Plants often used in Eastern coastal gardens
| Plant | Best position | Notes |
|---|---|---|
| Screw pine (Pandanus odoratissimus) | Exposed front edge, along fences | Spiny leaves; keep away from paths |
| Beach naupaka (Scaevola taccada) | Windbreak shrubs and hedges | Good salt tolerance; can be trimmed as a hedge |
| Beach morning glory (Ipomoea pes-caprae) | Ground cover on sandy soil and banks | Spreads fast; needs a defined edge |
| Manila grass (Zoysia matrella) | Lawns near the sea | More salt-tolerant than many lawn grasses; needs sun |
| Bougainvillea | Full sun, trellises | Drought-tolerant; flowers best without overwatering |
| Frangipani (Plumeria) | Medium feature tree | Tolerates sun and wind; seasonal leaf drop |
| Tropical almond (Terminalia catappa) | Large shade tree | Needs root space; heavy leaf fall; avoid next to pools |
| Alexandrian laurel (Calophyllum inophyllum) | Large coastal tree | Handsome canopy; relatively slow-growing |
| Coconut and coastal palms | Tall canopy, focal points | Mind falling fruit and fronds near paths |
Salt tolerance depends on distance from the sea, soil and establishment care. Treat this table as a starting point, not a purchase list — species and sizes should be confirmed after a site check.
Sandy soil and water
Coastal soil is often sand that drains quickly and holds few nutrients. During establishment, add organic matter, mulch to reduce evaporation, and rinse leaves with fresh water after strong winds or storms. On newly filled plots, check drainage first — waterlogging can kill roots faster than salt.
Materials and fittings near the sea
- Use marine-grade stainless steel (such as 316) or rust-free materials for screws, hinges and light fixings
- Plan re-coating for outdoor timber and expect it to weather with sun and salt
- Have specialists select lighting and irrigation protection ratings for the actual location
- Rinse salt from stone and furniture regularly to extend their life
Checklist before landscaping a coastal home
- Which side faces the sea wind and which is sheltered
- Is the soil sand, fill, or does water pond after rain
- Who will care for the garden and how often
- Which hours of the day need shade
