Everything it needs
9 essentials at a glance
Watering
Pachypodium lamerei prefers to dry out between waterings.
Water thoroughly when the top 2-3 inches of soil feel dry, typically every 2-3 weeks during the growing season (spring and summer) and less frequently in fall and winter. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and shriveling.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placement is near a south-facing window or outdoors in a sunny spot. It can tolerate partial shade but may not grow as vigorously.
Soil
Pachypodium lamerei prefers well-draining soil with a pH range of 6.0 to 7.0.
A recommended potting mix includes cactus or succulent soil, amended with perlite or sand to enhance drainage.
Humidity
This plant prefers low to moderate humidity levels, ideally around 30-50%.
To increase humidity, you can mist the plant occasionally or place a humidity tray nearby. Signs of humidity stress include browning leaf tips and wilting.
Temperature
Pachypodium lamerei thrives in temperatures between 70-85°F (21-29°C) during the day and can tolerate down to 50°F (10°C) at night.
It is suitable for USDA hardiness zones 10-12 and should be protected from frost.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 or 20-20-20.
Fertilize every 4-6 weeks during the growing season and reduce frequency in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Pachypodium lamerei in late winter or early spring to shape the plant and remove any dead or damaged leaves.
Use clean, sharp pruning shears and make clean cuts. Deadheading is not necessary as it does not produce flowers regularly.
Repotting
Repot every 2-3 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Carefully remove the plant from its pot, trim any damaged roots, and place it in fresh soil.
Propagation
Propagation is typically done through stem cuttings.
Take a healthy cutting of about 6 inches, allow it to callous for a few days, then plant it in a well-draining mix. Best timing is in spring or early summer when the plant is actively growing.

Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks with a balanced fertilizer to promote healthy growth.
Summer
During summer, ensure the plant receives full sun and monitor for signs of dehydration. Water thoroughly when the topsoil dries out, and consider misting to increase humidity.
Fall
In fall, gradually reduce watering as the plant enters dormancy. Continue to provide bright light but be cautious of cooler temperatures.
Winter
In winter, limit watering to once a month or when the soil is completely dry. Keep the plant in a warm location, away from drafts and cold windows.
