How to Grow Euphorbia trigona: Step-by-Step
1. Pick the Perfect Spot
Light is everything. Euphorbia trigona loves bright, indirect light.
-
Indoors: A sunny south- or east-facing window is ideal.
-
Outdoors: Full sun to partial shade works well. In very hot climates, offer some afternoon shade to prevent sunburn.
Avoid dark corners. This plant won’t thrive without strong light.
2. Choose the Right Soil
This succulent hates wet roots. Well-draining soil is a must.
DIY succulent soil mix:
-
2 parts cactus or succulent potting mix
-
1 part sand
-
1 part perlite or pumice
This keeps the roots dry and happy.
3. Plant It Properly
You can plant in a pot or directly in the ground (in warm climates).
-
Always use a pot with drainage holes.
-
Place the plant so the base sits just above the soil line.
-
Avoid burying it too deep.
-
Gently loosen the roots, set it in place, and press the soil lightly to secure.
4. Water the Right Way
Watering is where most people go wrong. Follow this simple rule: dry soil before water.
-
Check first: Let the soil dry completely before watering again.
-
Deep soak: Water thoroughly, then let excess drain out.
-
Winter rest: Water sparingly during cooler months when the plant slows down.
Warning signs: Yellow, mushy stems mean overwatering. If this happens, stop watering and let the plant dry out.
5. Keep It Warm
Euphorbia trigona loves warmth. Aim for 65–75°F (18–24°C).

Protect from frost—bring indoors if temperatures drop below 50°F (10°C).
-
Keep away from drafty windows or cold doors.
-
Humidity isn’t a concern; it does fine in dry indoor air.
6. Feed for Growth
During spring and summer, give it a little boost:
-
Use a balanced, water-soluble fertilizer.
-
Dilute to half strength.
-
Feed once a month.
Skip feeding in fall and winter.
