Understanding the Palm Drip Line and Fertilizer Application

What Is the Drip Line?

The drip line is the outermost reach of the palm's fronds. Imagine a circle on the ground directly under the furthest frond tips—that's the drip line. Most feeder roots concentrate in this zone.

Broadcasting Granular Fertilizer

Spread fertilizer evenly from the drip line inward toward the trunk, like feeding chickens. A typical rate is 1 pound per inch of trunk diameter, applied three times per year (spring, summer, fall). Water thoroughly after application to move nutrients into the root zone.

Dealing with Landscape Rocks

If rocks cover the root zone, you can leave them in place—provided there is no weed barrier beneath. Granules will dissolve and seep through the rocks. The empty shells you see later are just the carrier; nutrients have already been released.
