Troubleshooting
Warty Gasteria problems — and how to fix them
Warty Gasteria (Gasteria carinata var. verrucosa) 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.
Overwatering and rot
Soggy soil turns leaf bases mushy and translucent and rots the roots. Let the mix dry fully between waterings and grow in fast-draining, gritty compost.
Fungal leaf spot
Black or brown spots appear in humid, poorly ventilated, wet conditions. Improve airflow, keep water off the leaves, and remove badly affected foliage.
Stretching in shade
Too little light causes loose, pale, elongated growth and faded warty markings. Shift to brighter indirect light for compact, well-textured leaves.
Mealybugs
Cottony pests lodge among the tubercles and in leaf joints. Treat by spot-touching with isopropyl alcohol and inspect new plants before bringing them in.
