Arizona's Best Manganese Sulfate

Arizona’s Best Manganese Sulfate enhances iron uptake to help with the prevention of chlorosis (yellowing leaves and fronds). Recommended for Queen Palms, which are susceptible to “frizzle top” and can also be used on other varieties of palms.

Timing: Apply one to three times a year, depending on the severity of the chlorosis, during the growing season (March through October).  

Rate: Evenly sprinkle two tablespoons for each inch of trunk diameter around the base of each palm and work into the soil. Water thoroughly after application.
