Palm trees are one of the most easily recognized trees in the world. Although they are indigenous to tropical and subtropical climates, palm trees are popular additions to landscaped areas that do not have heavy frosts, and indoors as potted plants. There are more than 2,500 species of palm trees and all of them are prone to magnesium deficiency if not properly cared for. Epsom salt for palm trees is an excellent source of magnesium.
What is Epsom Salt?
Epsom salt is magnesium sulfate. It gets its name from the wells in Epsom, England where it was first discovered many years ago. In addition to many medicinal uses for Epsom salt, it is also an effective natural fertilizer for many plants and flowers, including palm trees.

To apply Epsom salt to outdoor, grown palm trees, spread 2 to 4 pounds of Epsom salt over the root zone approximately four times a year. Add water to the Epsom salt so that the soil and roots can absorb it more easily. Even if commercial palm tree fertilizer is available, try alternating it with Epsom salt every other month.
Epsom Salt for Palm Trees: Indoor or Parlor Palms
Since outdoor palm trees usually grow in zones 10 to 12. Plant owners farther north may choose to have a palm tree inside and grow it in a container as a houseplant.
Indoor palms, also called parlor palms, can also benefit from the magnesium sulfate present in Epsom salt.
Salt from commercial fertilizers can build up in the potting soil of parlor palms.
This can cause palm leaves to yellow and wither and can also cause root damage. One of the great things about Epsom salt is it will attach to harmful types of excess fertilizer salts in the soil and remove them.
To draw out the damaging salts that have built up in potted plant soil, apply a mixture of 1 teaspoon of Epsom salts with 1 gallon of water. Place the palm tree container in the bathtub or other deep sink. Slowly pour the Epsom salt mixture into the pot. Allow the container to drain completely before returning it.
