The Impact of Saltwater and Wind on South Florida Plants

Living in South Florida means enjoying sunshine, coastal breezes, and the beauty of the beach. However, the salty, balmy air can also lead to rusted metal objects and wreak havoc on your plants and trees.

The Effects of Saltwater Wind

During periods of high winds and low rainfall, easterly winds sweep across beaches and properties, delivering saltwater droplets that cling to surfaces. Without rain to wash it away, the moisture evaporates, leaving behind corrosive salt that:

  • Covers every leaf, bud, twig, and needle
  • Damages the protective scales on plants
  • Grinds tender buds and leaves with abrasive salt crystals

A single gallon of seawater contains 27 teaspoons of salt, which acts as both a corrosive and abrasive force. Over time, this results in plants with a dull, tattered, and burned-out appearance.

Choosing Salt-Tolerant Plants

To maintain a vibrant landscape in coastal areas, landscapers and gardeners must consider salt tolerance when selecting trees and plants. Popular salt-tolerant options include:

  • Palms: Coconut and Sabal palms
  • Trees and Shrubs: Sea Grapes, Green Island Ficus, and Clusia
  • Smaller Plants: Variegated Peperomia, sun-loving Agave, and fern-like Cardboard palms
  • Ground Cover: Ice plant (Aptenia), Baby Sun Rose, and Spartina grass
  • Fruit-Bearing Plants: Garcinia
  • Ornamental Options: Silver Buttonwood
