Euphorbia clavarioides problems — and how to fix them
Euphorbia clavarioides (Euphorbia clavarioides) 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.
Cushion rot
The dense mat rots readily if kept damp or humid. Water only when bone-dry, top-dress with grit, ensure strong airflow, and keep completely dry in winter.
Loose, stretched cushion
Too little light slackens the tight dome and pales the branches. Give full direct sun or strong supplemental lighting.
Mealybugs and root mealybugs
Hide among the packed club branches and in the roots. Treat foliage with 70% isopropyl alcohol and inspect the rootball when repotting.
Latex contact injury
Breaking a branch releases caustic milky sap. Wear gloves and eye protection when handling, dividing, or grooming the cushion.
