Use and Management

One old man palm may be all that is needed in a small landscape, but they can be planted en mass if room and budget permit. They appear to be standing like soldiers with their stiff, bearded trunks emerging straight from the ground. Good drought and salt tolerance makes them well adapted for planting along the seashore with some protection.

Pests and Diseases

There appears to be no major pest or disease problems.
