Propagating a Mature Madagascar Palm (Pachypodium lamerei)

A 30-year-old, 7–8 foot Madagascar palm needs size reduction. The owner asks whether to root the top or keep the base.

Best Timing

Wait until early summer (June) for propagation – warmer temperatures improve success.

Propagation Options

Option 1: Root the Top Cutting

1. Cut a healthy section of the stem (wear gloves – sap is toxic, thorns are sharp).
2. Let the cut end callous in bright, indirect light for 1–2 weeks.
3. Plant upright in cactus soil with exceptional drainage.
4. Water very conservatively: no more than 1 cup every 3 weeks until roots form.

Success rate: ~50%.

Option 2: Keep the Base

The remaining base may produce a new branch (also ~50% chance). This preserves the established root system.

Seed Propagation

Seeds are slow to germinate (~1 month), don't store well, and are hard to find. Cuttings are more practical.

Critical Care

• Excellent drainage is non-negotiable.
• Protect from cold – keep above 50°F (10°C).
• Full sun preferred.
