Troubleshooting
Saucer Plant problems — and how to fix them
Saucer Plant (Aeonium undulatum) 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.
Etiolated, stretched trunk
Stem elongates and the rosette opens flat when light is insufficient. Move to the brightest available window; the lengthened stem will not shrink back.
Stem and crown rot
Mushy, browning trunk from overwatering, especially during summer dormancy. Cut back watering, improve drainage, and behead to a healthy section if rot has set in.
Summer leaf drop
The rosette tightens and lower leaves shrivel and fall in hot, dry weather. This is normal protective dormancy, not death; resume normal watering as cooler weather returns.
Mealybugs
White cottony clusters hide in the rosette centre and leaf joints. Wipe off with a cotton bud dipped in 70% isopropyl alcohol and inspect regularly.
Prevent saucer plant problems before they start
Most saucer plant issues are care-mismatch, not bad luck. Dial in the basics:
