Troubleshooting
Firesticks Plant problems — and how to fix them
Firesticks Plant (Euphorbia tirucalli 'Sticks on Fire') 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.
Caustic latex sap
Not a disease but the plant's chief hazard: the sap badly burns skin and can cause serious eye injury. Wear gloves and goggles, work in ventilation, and never touch your face when handling.
Soft, rotting stem bases
Overwatering or poor drainage. Let soil dry fully, use gritty mix, and cut back to firm tissue if rot sets in, letting cuts callus.
Colour reverts to green
Too little light or too much warmth and water. Give maximum sun and lean conditions; cooler temperatures also deepen the fiery tones.
Leggy, floppy stems
Low light causes weak etiolated growth. Move to a much brighter spot and support tall stems, as they are brittle and snap easily.
