Troubleshooting
Euphorbia resinifera problems — and how to fix them
Euphorbia resinifera (Euphorbia resinifera) 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.
Crown rot
Standing moisture in the dense mound triggers rot. Water only when fully dry, ensure strong drainage, and provide good airflow around the crown.
Loose, stretched mound
Too little light slackens the compact form. Give it the sunniest spot available or add supplemental lighting.
Mealybugs and root mealybugs
Hide in stem grooves and among roots. Treat foliage with 70% alcohol on a swab and check the rootball at repotting.
Severe latex burns
Resiniferatoxin makes the sap exceptionally caustic. Always wear gloves and eye protection, and avoid handling in windy conditions where droplets can spread.
