Troubleshooting
Spiny Adenia problems — and how to fix them
Spiny Adenia (Adenia spinosa) 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.
Caudex rot from dormancy watering
Watering during the leafless winter dormancy is the primary cause of plant loss. Even a small amount of water at low temperatures can initiate fungal rot within the caudex. Maintain a bone-dry substrate from leaf fall until new growth emerges the following spring.
Etiolated, thin caudex
Insufficient light causes the caudex to remain thin and elongated rather than swelling into the characteristic fat, round shape. Relocate to maximum available light and supplement with a grow light in winter if natural light is limited.
Aphid infestations on new growth
Soft new vine tips and emerging leaves can attract aphid colonies in spring. Blast off with a strong jet of water and treat with insecticidal soap or neem oil; repeat every 5–7 days. Avoid systemic insecticides if the plant is kept in an outdoor space accessible to wildlife.
