Answer: According to the Florida Extension Service, "'Palm Special' fertilizers are available with chelated micronutrients that contain a ratio of N:P:K:Mg of 2:1:3:1 for sandy, nutrient-poor soils. To ensure a steady supply of nutrients, multiple applications are recommended at a rate of 1.5 pounds per 100 square feet of canopy 4 times per year, or alternatively at 1 pound per 100 square feet of canopy 6 times per year. N, K, and Mg should be in controlled- release form to provide nutrients over a 3-month period. When possible, dry, granular fertilizers should be broadcast under the palm canopy, not up against the trunk and not in bands around the trunk." You will find specially formulated palm fertilizers in your local garden center.
Best wishes with your Queen palm!
