Epsom salts is Magnesium sulfate. It will provide the magnesium that your palms need. You have to do it over and over. The University of Florida recommends either the Lesco 8-2-12 plus 4 available at John Deere or Howards 8-2-12 available at Fairfield Farms or BGI 8-2-12 from Home Depot. Magnesium is one of the trace elements that are included in these palm specialty fertilizers, eliminating the need for epsom salts or adding boron or iron or manganese, or other trace elements. These 8-2-12 formulas work quite well on you lawns and shrubs as well.
