Troubleshooting
Star Window Plant problems — and how to fix them
Star Window Plant (Haworthia retusa) 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.
Reddening or browning leaves
Too much direct sun. The windowed leaves scorch and blush red-brown; move to bright indirect light to recover.
Soft, mushy, translucent leaves
Overwatering and rot. Let soil dry fully, water at the base, and repot into grittier mix, trimming any rotted roots.
Cloudy or shrinking windows
Underwatering or age; the translucent tips lose plumpness when thirsty. A thorough soak restores them; very old leaves naturally dry from the outside.
Mealybugs and root mealybugs
White pests lurk in the rosette and on roots. Treat with isopropyl alcohol or insecticidal soap and check the root ball when repotting.
