How to Landscape to Tolerate Salt Water

Plan the landscape, taking note of how much protection is afforded by existing walls and structures. Pay attention to areas that are be subject to direct spray from the ocean or where runoff from winter de-icing may drain. Rugosa roses, yaupon holly and the southern magnolia are salt-tolerant specimens that may brighten up the seaside landscape. Many plants are salt-tolerant. Some plants grow only in salty soil and are halophytic, or salt-loving specimens.

Take a soil test to determine the salinity of the soil. Tests are available from the local cooperative extension service or at garden and home improvement centers. Improve the soil by adding organic amendments. This will increase drainage and allow salt to be leeched from the soil.

Plant uphill or on a berm to encourage salts to wash away. Keep plant specimens as stress-free as possible by locating in the proper sunlight and applying appropriate fertilizer and water. Unstressed plants are less likely to be damaged by sea spray and storms.

Remove salt spray from plants after a storm when possible to prevent damage to the above-ground plant parts. Use a garden hose to rinse some sea spray from plant material.

Plant a windbreak or barrier to redirect or deflect salt spray during storms. Take advantage of walls and tall fences that act as barriers to wind-blown salt.
