Troubleshooting
Natal Plum Bonsai problems — and how to fix them
Natal Plum Bonsai (Carissa macrocarpa) 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.
Few or no flowers/fruit
Almost always insufficient light. Move to the sunniest position and feed with a higher-potassium fertiliser in the growing season.
Leaf drop and yellowing
Usually from overwatering and soggy roots, sudden cold drafts, or moving the plant. Let soil dry between waterings and keep it warm and stable.
Thorn injuries when working
The stiff, forked spines are sharp; wear gloves and prune carefully when wiring or pinching.
Scale and mealybugs
Sap-suckers hide in branch crotches under glass. Wipe off with diluted insecticidal soap or horticultural oil and improve airflow.
