Madagascar Palm (Pachypodium lamerei)

Quick Overview

• 🌞 LIGHT: Direct sunlight to bright, indirect light (needs high light).

• 💧 WATERING: Water when 75–100% of the soil is dry; drought-tolerant succulent tree.

• 🌡️ TEMPERATURE & HUMIDITY: 65–85°F (18–29°C) & low to average household humidity.

• 🌱 SOIL: Exceptionally gritty, fast-draining cactus/succulent mix with a drainage hole.

• ❗ SAFETY NOTE: Highly toxic to pets and humans if ingested (contains cardiac glycosides). Spines can cause physical injury. Keep out of reach.

All the Details

🌞 More about LIGHT

• Tolerates: Full direct sunlight (at least 4–6 hours daily indoors).

• Avoid: Low light or medium indirect light, which leads to weak, soft growth, stem rotting, and heavy leaf dropping.

• Pro Tip: Position in your brightest southern or western window. Rotate the pot a quarter-turn monthly to keep the main thorny trunk growing straight toward the light.

💧 More about WATERING

• Frequency: Typically every 2–3 weeks in spring and summer. In late autumn and winter, cut watering back to once every 4–6 weeks (or pause entirely if dormant).

• Avoid: Overwatering—storing water in its thick, swollen trunk (caudex) makes it extremely vulnerable to root and trunk rot. Never leave the pot sitting in standing water.

• Winter Dormancy: It is completely natural for a Madagascar Palm to drop its long, palm-like leaves in winter. Reduce watering drastically until new leaves sprout in spring.

🌡️ More about TEMPERATURE & HUMIDITY

• Draft Sensitivity: Extremely sensitive to cold temperatures. Keep away from cold winter drafts, chilly windowpanes, and exterior doorways. Temperatures below 55°F (13°C) cause severe damage.

• Humidity: Thrives in dry, low-humidity air. No misting, humidifiers, or extra humidity boosts are needed.

🌱 More about SOIL & REPOTTING

• Soil Mix: Requires maximum drainage to prevent water retention around the base. Combine 2 parts cactus/succulent soil mix with 1 part perlite, pumice, or coarse sand.

• Repotting: Repot every 2–3 years in spring as it grows. Use thick leather gloves or wrap the spiky trunk in rolled heavy towels or cardboard to protect your hands while repotting.

🌸 FERTILIZING

• Routine: Feed 2–3 times total during the active spring and summer growing season using a balanced cactus or houseplant fertilizer diluted to half-strength.

• Rest Period: Do not fertilize during late autumn or winter when the plant is dormant.

✂️ PRUNING & MAINTENANCE

• Pruning: Pruning is rarely necessary. If the plant grows too tall, the main stem tip can be cut using clean, sharp tools, which will force it to branch out at the top.

• Cleaning: Dust rarely builds up on the narrow leaves, but you can gently blow away dust or wipe leaves carefully to avoid the sharp trunk spines.

🪴 PROPAGATION

• Offshoots / Pups (Primary Method):

  1. Carefully detach small side-pups growing near the base or trunk using a clean, sharp knife.

  2. Allow the cut end of the offshoot to dry out and form a callous for 4–7 days.

  3. Plant the calloused pup into a dry cactus mix, place in bright light, and water sparingly until roots establish.
