- A summer grower: while in leaf, water thoroughly once the soil has dried through, as a guide, and stay sparing until growth starts in spring.
- Autumn (Oct–Nov)
- Every 14 days
- Once the leaves color and start to fall, water lightly one to two weeks after the soil dries, as a guide.
- Winter (Dec–Feb)
- Every 30 days
- While leafless keep it almost dry, with about one light moistening a month on a warm morning.
Light and placement for Pachypodium horombense
From spring to fall, generally a sunny outdoor spot out of the rain; full sun keeps the branches short and helps its bell-shaped yellow flowers form in spring, and indoors a south window suits it.
Overwintering Pachypodium horombense
Overwintering guide: 5°C (41°F) or above
As a guide, move it into a sunny room when nights fall below about 10°C and keep it above 5°C; once leafless keep it nearly dry and pull it back from cold window glass at night.

Common problems with Pachypodium horombense
- Watered as usual while leafless in winter, the roots and trunk rot.
- Too little sun stretches the branches and stops flower buds forming.
- Left out in the long rains of early summer, the roots suffer from the damp.
Tips for growing Pachypodium horombense
- A trunk that gives when pressed gently suggests thirst; a firm one has enough.
- A gritty, fast-draining mix lets you water generously in the growing season.
- Care varies with the plant's size and conditions, so adjust by watching the leaves.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
