Graptopetalum pentandrum problems — and how to fix them
Graptopetalum pentandrum (Graptopetalum pentandrum) 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.
Etiolation (stretching)
Insufficient light makes the rosette loosen and stems elongate toward the window. Move to brighter light; behead and re-root the leggy top to restart a compact rosette.
Root rot from overwatering
The most common killer. Soggy soil turns leaves mushy and translucent and blackens stems. Use gritty mix, a draining pot, and the soak-and-dry method; cut away rot and re-root healthy tissue.
Mealybugs and spider mites
Mealybugs hide as cottony white masses in leaf crevices; mites cause fine webbing. Dab with a 70% isopropyl alcohol swab or treat with neem oil/insecticidal soap, repeating until clear.
Sunburn
Sudden intense or reflected summer sun scorches leaves with brown, dry patches. Acclimate to strong light gradually and provide light afternoon shade in the hottest months.
Rubbed-off farina
The chalky pale coating (epicuticular wax) is permanent where touched and won't regrow on that leaf. Handle by the stem and only new growth restores the ghostly bloom.
Stretched growth won't re-compact
Once a section etiolates it stays loose even after light improves. Only new central growth will be tight, so prune or propagate to refresh the shape.
