Troubleshooting
Euphorbia Trigona 'Rubra' problems — and how to fix them
Euphorbia Trigona 'Rubra' (Euphorbia trigona 'Rubra') 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.
Soft, brown rotting stem
Overwatering or poor drainage causing rot, often from the base up. Cut well above rot into clean tissue, let it callus, and replant in dry gritty mix.
Stems lean or topple
Tall growth becomes top-heavy, worsened by low light stretching. Stake if needed, use a heavy pot, and give brighter light to keep stems sturdy.
Red colour fades to green
Insufficient light. Move to a brighter spot with some direct sun to restore the burgundy tones.
Irritant sap on cutting
Not a disease but a hazard: the latex burns skin and eyes. Always wear gloves and eye protection and wash off sap promptly when pruning.
