Troubleshooting
Euphorbia antisyphilitica problems — and how to fix them
Euphorbia antisyphilitica (Euphorbia antisyphilitica) 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 and stem rot
Yellowing, softening or collapsing stems from overwatering or poor drainage. Let the mix dry fully between drinks and use a gritty, free-draining medium.
Floppy, etiolated stems
Weak, leaning, pale stems indicate inadequate light. Move to the brightest available position or add supplemental lighting.
Irritant latex
Cut stems exude caustic sap that burns skin and eyes. Wear gloves, wash off any contact, and keep hands away from your face.
Mealybugs
White cottony insects cluster at stem bases. Dab with isopropyl alcohol and improve airflow around the clump.
