Troubleshooting
Crassula Undulata problems — and how to fix them
Crassula Undulata (Crassula ovata 'Undulata') 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
Soggy soil rots roots and stems. Let the mix dry fully between waterings, use gritty compost and cut back water in winter.
Leggy, flattened growth
Too little light stretches the stems and reduces the leaf curl. Provide bright, direct sun to keep the plant compact and well-coloured.
Shrivelled leaves
Persistent underwatering wrinkles the fleshy leaves. Give a thorough soak once the soil is fully dry to plump them back up.
Mealybugs
Cottony clusters lodge in the curled leaf axils. Treat with isopropyl alcohol on a cotton bud and repeat until no pests remain.
