Troubleshooting
Gasteria Obliqua problems — and how to fix them
Gasteria Obliqua (Gasteria obliqua) 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.
Crown and root rot
Caused by overwatering or water pooling in the leaf fan. Water at the soil line, let it dry fully, and use a gritty, free-draining mix.
Sunburn
Harsh direct sun bleaches and scorches the leaves, sometimes reddening them. Provide bright indirect light and shield from intense afternoon sun.
Fungal leaf spot
Black or brown spots appear in damp, stagnant conditions. Improve airflow, keep foliage dry, and avoid overhead watering.
Mealybugs
Cottony pests lodge in leaf axils. Treat with isopropyl alcohol on a swab and check offsets and the crown regularly.
