Planting
How to Grow
- Select a location receiving at least 6 hours of direct sun.
- Ensure the soil is sandy and drains very quickly.
- Dig a hole twice the width of the container but no deeper.
- Gently place the palm in the hole, keeping the root ball intact.
- Backfill with soil and water deeply to eliminate air pockets.
- Avoid fertilizing for the first few months after planting.
Pro Tip
Provide ample space for its massive crown to develop and plant in the sunniest, best-draining spot available.

Care Guide
Do
- Water deeply but infrequently once established.
- Fertilize with a palm-specific fertilizer 2-3 times during the growing season.
- Prune only dead or dying fronds; avoid over-pruning.
- Give it plenty of room to grow to its mature size.
Don't
- Don't plant in heavy clay or poorly drained soils.
- Avoid overhead irrigation, which can encourage fungal issues.
- Don't attempt to transplant a mature specimen; they resent root disturbance.
- Never cut the central growing point or 'heart'.
