Palms have special requirements when it comes to fertilizer. Palm production worldwide is a multi million pound business and much research has gone into palm fertilizer requirements. We have put together a special formula at a very affordable price based on the latest research (using the well known NPK ratio 3-1-3). This fertilizer doesn't cause accumulation of salts in the soil, which makes it an exceptional product. Salt in the soil is the main reason for palm-yellowing.
