Adansonia digitata

Natural range and habitat of Adansonia digitata

Adansonia digitata is native across tropical and southern Africa and the southern Arabian Peninsula. It grows in savanna, dry woodland and rocky open country with pronounced wet and dry seasons.

The trunk stores water during periods of rainfall. Leaf fall reduces water loss during the dry season, and established trees resume growth when rain and warmth return.

Care for Adansonia digitata

• Light: Give the plant the brightest position available, including direct sun after acclimation. Weak light produces thin, stretched stems.
• Temperature and airflow: Maintain roughly 20–35 °C. If conditions approach 12 °C, move the plant away from the cold source. Warm conditions support active growth. During the leafless rest, keep the dry root system frost-free and away from wet potting mix; gentle airflow helps the swollen base (caudex) remain dry. Keep sustained exposure below 15 °C to a minimum.
• Humidity: Dry to average indoor air is appropriate during both growth and rest.
• Water: During warm leafy growth, water thoroughly and let the mix dry well before watering again. When the plant is leafless, keep it much drier and water only enough to prevent severe shrivelling.
• Potting mix: Use a mineral-rich caudex or succulent mix in a pot with drainage holes. Use a deep pot that closely fits the developing root system.
• Feeding: Supply diluted balanced fertiliser during leafy growth. Pause when the plant is bare and inactive.
• Repotting: Increase pot size when roots crowd the container and need more room. If drainage deteriorates, refresh the mix without enlarging the pot unless root space is also needed. Keep the swollen base (caudex) at the same level.
• Propagation: Fresh seed is the usual method. Seedlings need warmth, strong light and careful watering as their base develops.
• Pruning: Shorten active stems to guide branching once the plant is established. Use clean tools and allow cuts to dry.

Root, stem and leaf problems in Adansonia digitata

• Leaf drop: Gradual loss during a cooler, darker or drier period is normal. A firm stem and base indicate rest; a soft base is consistent with active rot.
• Soft trunk or stem base: Rot is likely, especially in cold wet mix. Remove the plant from the pot, cut away decayed tissue and keep the remaining firm tissue dry until it seals.
• Firm, wrinkled trunk: The plant is using stored water. If it is leafless, do not respond with heavy watering; check temperature and substrate moisture first.
• Thin extended shoots: Light is insufficient. Increase direct light gradually and prune weak growth during the next active period.
• Yellow leaves during active growth: Check for wet roots, poor drainage and cold conditions before adding water or fertiliser.
• Mealybugs: Inspect new shoots, leaf bases and branch joints. Isolate and treat the plant before insects spread.

Keep Adansonia digitata away from children and pets

• Keep this plant away from children, cats and dogs.
• Its effects after chewing or swallowing are unclear, and plant material can still cause an upset stomach.
• Contact a veterinarian or medical professional if symptoms develop or do not settle.

Who first published Adansonia digitata, and what does the name mean?

Adansonia honours the French naturalist and botanist Michel Adanson. The Latin epithet digitata means fingered and refers to the mature leaves, whose leaflets spread like the fingers of a hand.

Carl Linnaeus established the genus Adansonia in 1759 in Systema Naturae, tenth edition, volume 2, pages 1144 and 1382.
