Troubleshooting
Elephant bush problems — and how to fix them
Elephant bush (Portulacaria afra) 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 rot from overwatering
By far the most common problem: soggy compost causes blackening, mushy stems and sudden collapse. Always let the mix dry out, use gritty soil and a pot with drainage holes, and water less in winter.
Leggy, stretched growth
In too little light the stems elongate, lean toward the window and leaves become sparse and pale. Move to a brighter spot and pinch the tips to encourage bushier, more compact growth.
Leaf drop
Sudden shedding of leaves usually follows a stress such as overwatering, severe drought, a cold draught or a big change in conditions. Stabilise watering and temperature and new leaves normally return.
Mealybugs and scale
Indoors it can attract white cottony mealybugs in leaf joints and brown scale on stems. Wipe off with a cotton bud dipped in dilute alcohol, or treat with an appropriate houseplant insecticide, and isolate affected plants.
