Fertilization regimen reduces environmental impact of landscape palms

(American Society for Horticultural Science) A study showed that areca palms can be grown in a native sand soil or in a calcareous fill soil without supplemental phosphorus, and with no nitrogen applied during the rainy summer months (June-September) in southern Florida. The study also demonstrated that the negative effects caused by high nitrogen:potassium ratio turf fertilizers can be mitigated by adding a controlled release palm fertilizer that contains no nitrogen or potassium.
