Troubleshooting
Coarctata Haworthia problems — and how to fix them
Coarctata Haworthia (Haworthiopsis coarctata) 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
Soft, translucent or blackening lower leaves indicate root or stem rot; let soil dry fully and improve drainage.
Stretching in low light
Towers that lean and elongate with gaps between leaves need more light; relocate closer to a bright window.
Sunburn
Whitened or scorched patches follow abrupt full-sun exposure; acclimate slowly and avoid harsh afternoon sun behind glass.
Mealybugs and root mealybugs
Check leaf joints and roots for white cottony masses; isolate and treat with isopropyl alcohol or insecticidal soap.
