Troubleshooting
Grandidier's Baobab problems — and how to fix them
Grandidier's Baobab (Adansonia grandidieri) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Trunk rot
Over-watering, especially during dormancy, leads to fungal rot spreading from the roots into the water-storing trunk tissue. This is usually fatal. Use very gritty compost and a clay or terracotta pot.
Seed dormancy and slow germination
Seeds have a hard, impermeable coat. Without scarification (sanding or nicking) and repeated hot-water soaking, germination rates are very low and erratic. Expect 3–12 weeks even with correct treatment.
Cold stress
Temperatures below 10°C slow growth markedly and below 5°C may kill young specimens even if kept dry. Provide a heated greenhouse or a bright, warm indoor position in winter.
