Maintenance
- Water regularly during the first 6–12 months after planting to help establish roots. Allow soil to dry slightly between waterings.
- Drought-tolerant once established; water deeply during extended dry periods, especially in hot climates
- Apply a slow-release, palm-specific fertilizer 2–3 times per year (spring, summer, and early fall) for optimal growth and color.
- Remove only fully dead or damaged fronds. Avoid over-pruning—leaves provide necessary nutrients and structure. Do not cut green fronds.
- Apply a 2–3 inch layer of mulch around the base (keeping it a few inches from the trunk) to retain moisture and suppress weeds.
- Allow at least 10–15 feet of clearance from structures and other plants to accommodate the wide canopy and trunk growth.
