Welwitsch's Anchomanes problems — and how to fix them
Welwitsch's Anchomanes (Anchomanes welwitschii) 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.
Tuber rot during dormancy
The most common failure point. If the tuber is kept moist or cold when dormant, it quickly rots. Lift the tuber after the leaf dies back, allow to dry briefly, then store in barely moist coir at 18–22°C until signs of new growth appear.
Failure to produce leaf after dormancy
Insufficient warmth or light during the growth trigger period delays or prevents emergence. Ensure temperatures remain above 20°C and provide bright indirect light to encourage bud break in spring.
Spider mites in dry conditions
Low humidity encourages spider mite infestations on the large leaf. Maintain 60%+ humidity and inspect the underside of leaves regularly. Treat with insecticidal soap or neem oil spray.
