Palm & Tree Fertilization
Palms like an NPK ratio of 3:1:3. Trace elements, such as sulfur, zinc, boron, and copper, are also extremely important to palms. Some palm fertilizers are granular, while others come in the form of spikes which are inserted into the ground beneath the palm's canopy. Water the fertilizer in completely. Different trees need different types of fertilizer. Visit your local nursery to discover the type that's best for your specimen.
