Cultivation and Uses
USDA hardiness zones: 9-11. Hardy to 18°F.

Sun: Full sun. This palm is intolerant of heavy shade.
Drought tolerant: Yes.
Water after becoming established: Water deeply 1-2 times a month, but 3-4 times a month in temperatures over 85°F. Additional water speeds growth.
Soil: Very well drained, tolerant of soil types otherwise, ph 6.1-9.0 (slightly acidic to highly alkaline). This palm is salt tolerant.
Fertilize: A magnesium (Mg) deficiency might occur in highly alkaline soil. This will appear as leaflets that are yellow from the tip to about half-way up. The center will stay green. A palm fertilizer with magnesium can be applied late winter to early spring to correct the problem and/or to provide faster growth.
Mulch: No.

Litter: Wet fruit drop, infrequent frond drop.
Propagation: Seed, which takes 2-4 months to germinate.
