Troubleshooting
Gasteria Armstrongii problems — and how to fix them
Gasteria Armstrongii (Gasteria armstrongii) 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.
Root rot from overwatering
Its slow growth and thick leaves make it very rot-prone if watered too often. Let the soil dry fully and use a sharply draining, gritty mix.
Sunburn
Harsh direct sun bleaches and scars the dark, rough leaves. Keep in bright indirect light and shade from intense afternoon sun.
Slow recovery from damage
Because growth is so slow, scarred or damaged leaves persist for a long time. Prevent injury and pest damage rather than relying on quick regrowth.
Mealybugs
Cottony pests settle in the leaf fan and base. Remove with isopropyl alcohol on a swab and inspect regularly.
