Plants For Gardening With Salt Water Soil

Found predominantly along sea coasts or tidal rivers and estuaries, salty soils occur when sodium builds up in the soil. In most areas where rainfall is above 20 inches per year, salt accumulation is rare because the sodium is quickly leached from the soil. However, even in some of these areas, runoff from winter salted roads and sidewalks and salt spray from passing vehicles can create a microclimate in need of salt resistant gardens.

Growing Salt Resistant Gardens

If you have coastal garden where sea salt will be a problem, don’t despair. There are ways to combine gardening with salt water soil. Salt tolerant shrubs can be used to form wind or splash breaks that will protect less tolerant plants. Trees that tolerate salty soil should be planted closely to protect each other and the soil beneath. Mulch your garden of plants that tolerate salty soil and spray them regularly and thoroughly, particularly after storms.
