I grew a Sago Palm from a pup and planted it in memory of my husband at his golf club. It is about 3 feet tall and I think it needs fertilizer. My Home Depot has no palm tree fertilizer and says none can be stocked on their shelves now due to fertilizer getting into streams, etc. I have thrown Epsom Salts around my Pygmy Palms and they are doing well. Could I do the same with the Sago? I live in Florida.
