Troubleshooting
Moonstones problems — and how to fix them
Moonstones (Pachyphytum oviferum) 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 and stem rot from overwatering
The most common killer. Mushy, translucent, or blackening leaves and stems mean too much water or poorly draining soil. Use gritty mix, a pot with drainage, and let soil dry fully between waterings.
Etiolation (stretching)
In too little light the rosette stretches, leaves space out and point upward, and colour fades. Move to a brighter spot or add a grow light; stretched growth will not revert and must be pruned or re-propagated.
Rubbed-off farina
The chalky white bloom on the leaves is a protective wax (sun and water barrier) that does not grow back. Avoid touching, wiping, or misting the leaves, and water at the soil line to keep the frosted look intact.
Mealybugs
White, cottony pests hide in leaf joints and under dead leaves. Remove spent leaves, isolate affected plants, and dab pests with 70 percent isopropyl alcohol or treat with insecticidal soap.
Sunburn
Sudden intense or unacclimatised afternoon sun, especially magnified through glass, causes brown scorched patches. Increase direct light gradually and shade from the harshest midday rays.
Wrinkled, soft leaves
Usually underwatering or root damage. If soil is bone dry, give a thorough soak; if soil is wet, suspect rot and check the roots instead of watering more.
