Euphorbia milii 'Rosea' problems — and how to fix them
Euphorbia milii 'Rosea' (Euphorbia milii 'Rosea') 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.
No flowers
Almost always insufficient light. Move to the brightest possible direct-sun spot and ease off water; bloom resumes within weeks.
Stem and root rot
Caused by overwatering or poor drainage. Soft, blackening stems mean it is too wet; switch to gritty mix and water only when bone-dry.
Leaf drop
Some leaf loss in winter or after a move is normal. Sudden heavy drop signals cold draughts, sharp light change or waterlogging.
Mealybugs and spider mites
Watch for cottony tufts in leaf joints or fine webbing. Wipe off and treat with insecticidal soap or diluted neem.
