Kentia palm for indoors (Howea forsteriana ) -
Once Kentia palm plants have established, they require very little care. Feed your container grown plants with a controlled release fertilizer with an NPK ratio of about 3-1-2. Excessive fertilization may cause the tips of lower leaves to turn brown and die. While normally carefree, they are prone to potassium deficiency. The first signs of this deficiency appear on the oldest leaves as necrosis on the tips. To manage this deficiency, apply a control release potassium supplement, as this is more effective than a water-soluble supplement. Kentia plants are also susceptible to deficiencies of manganese, which exhibits as leaf tip necrosis on the youngest leaves. Boron deficiencies may cause stunting of new leaves as well. Indoor grown palms rarely become diseased but may be plagued with spider mites, mealybugs, and scale insects. The use of insecticidal soap or neem oil can often help with any pest issues that may arise.
