Bench notesCare for this Euphorbia poissonii 3 Gallon Pot.
Euphorbia poissonii is a West African medicinal Euphorbia with thick, blunt-tipped, paddle-like terminal leaves on a stout, branching trunk. This 3-gallon plant carries the kind of base mass that takes a decade in cultivation.
Full Euphorbia care guide → - Light
- Full sun to brightest filtered light. The terminal leaves stay tighter and greener under hard light; under-lit plants drop their leaf clusters faster.
- Water
- Steady summer waterings with full dry-down. Reduce sharply in autumn; water only enough to prevent stem shrivel through winter.
- Soil
- Mineral-leaning cactus mix. The species' surface roots prefer a wide pot, ideally terracotta, that breathes well between drinks.
- Dormancy
- Cool-season slowdown rather than full dormancy. The leaves persist longer than most West African Euphorbias if temperatures stay above 60°F.
- Hardiness
- USDA 11 (50°F floor; the species shows cold damage early — black-tipped leaves a few days after the cold event).
- Feeding
- Half strength balanced fertilizer every three weeks in summer. None in winter.
- Repotting
