Troubleshooting
Candle Plant problems — and how to fix them
Candle Plant (Senecio articulatus) 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.
Summer leaf drop (often misdiagnosed as a problem)
Normal seasonal behavior — the candle plant is fully deciduous in summer. Do not increase watering to compensate. Reduce water sharply and wait for new leaf growth to emerge in autumn.
Stem rot at the joints
Overwatering causes soft, discolored sections at the stem nodes. Remove affected segments, allow the cut to dry for several days, and repot into fresh, very well-draining mix with reduced watering frequency.
Mealybugs at stem joints
The joints between stem segments are favored hiding spots for mealybugs. Inspect regularly and treat with isopropyl alcohol on a cotton swab or systemic insecticide if infestations are heavy.
