Troubleshooting
Alocasia Stingray problems — and how to fix them
Alocasia Stingray (Alocasia macrorrhiza 'Stingray') 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.
Brown, crispy leaf tips and edges
Almost always low humidity or inconsistent watering. Raise humidity above 60% with a tray or humidifier and keep the soil evenly moist (not wet).
Yellowing leaves
Usually overwatering or a waterlogged corm; let the top third of the mix dry between waterings and ensure the pot drains freely. Note that occasional yellowing of the oldest lower leaf is normal aging.
Drooping or weak, leggy stems
Often too little light or erratic watering. Move to a brighter spot with bright indirect light and water on a more consistent schedule.
Spider mites
Tiny webbing and fine stippling on leaves, encouraged by dry air. Wipe foliage, raise humidity, and treat with insecticidal soap or neem oil; isolate the plant while treating.
Mealybugs
White cottony clusters in leaf joints and undersides. Dab with isopropyl alcohol on a cotton swab and follow up with insecticidal soap or neem until clear.
Sudden leaf drop / winter dormancy
Alocasias can drop leaves or go semi-dormant in cool, low-light winter conditions. Reduce watering, keep the corm warm and barely moist, and growth typically resumes in spring.
