| Black curly fronds on new growth sounds like Frizzle Top. It's caused by a Manganese (Mn) deficiency. Some palms are more suceptible than others but if left untreated it will lead to the decline and death of the palm. See the following for more information. http://miami-dade.ifas.ufl.edu/programs/commorn/publications/Mn-deficiency-of-palms.PDF Your palm needs Manganese Sulfate (NOT Epsom salts, that's Magnesium Sulfate) Follow the label directions. Regular use of a Palm Special fertilizer should prevent the problem from coming back. |
