Spider mites
Fine, dusty webbing in the leaf joints plus pale stippling is a classic spider-mite infestation.
Diagnosis
Spider mites
What's happening
Spider mites love the thin leaves and the warm, dry air that Adansonii is often kept in. They cluster on the undersides and pierce the cells to feed, leaving a fine yellow-white speckling across the leaf and, as numbers explode, delicate webbing strung between leaves and stems. Left alone they spread quickly and can defoliate a vine.
How to fix it
Isolate the plant from your others right away. Rinse it thoroughly in the shower or sink, paying special attention to the leaf undersides, to knock down the population. Then spray every surface — tops, undersides, stems, and growth tips — with neem oil and repeat every 5–7 days for three to four weeks to catch newly hatched mites. Raising the humidity afterward makes the plant a far less inviting host.
What fixes it
- Neem oil for pests — Neem oil smothers spider mites and their eggs; coat every leaf surface and repeat weekly until they're gone.
If that doesn't fix it
This is general guidance based on common symptoms; individual plants vary.
