Pachypodium Lamerei Care — Madagascar Palm Growing Indoors

Pachypodium lamerei (Madagascar Palm) is a spiny caudex-forming succulent tree. Learn indoor growing tips for this dramatic conversation piece including winter dormancy management. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Pachypodium lamerei is not a true palm but a succulent with a thick spiny trunk and palm-like leaf tuft on top. Native to Madagascar where it grows in arid rocky areas reaching up to 20 feet tall in the wild. Indoors it typically reaches 3-6 feet over many years, growing in a distinctive bottle shape. The trunk stores water allowing it to survive extended drought and makes overwatering the main risk. It is deciduous and drops all leaves in winter as part of its natural dormancy cycle. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: The spiny thick trunk is an adaptation to store water and deter herbivores in arid Madagascar. Deciduous winter dormancy mirrors the dry season in its native habitat when water is unavailable. Bottom-heavy trunk shape provides stability in rocky substrate and maximizes water storage capacity. Slow growth rate of 2-4 inches per year in trunk height means it takes decades to reach full potential. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Provide maximum direct sun — 6+ hours daily in the sunniest window or under strong grow lights. Water thoroughly when soil is completely dry in summer — every 1-2 weeks depending on heat and pot size. Stop watering when leaves begin dropping in fall — resume only when new leaf buds appear in spring. Use extremely well-draining mineral-heavy soil in a terracotta pot for the best root conditions. Keep above 55°F at all times — cold damage can be fatal to this tropical succulent. If these steps do not resolve the issue, consider consulting additional resources or a qualified professional.
