Germination Process
Euphorbia corollata seeds require a period of cold stratification to germinate successfully.
Cold Stratification:

- Refrigerate for 60-90 days
Sowing Seeds:
- Fill seed trays with a well-draining seed starting mix
- Sow stratified seeds on the surface of the soil
- Lightly press seeds into the soil, but don’t cover them (they need light to germinate)
- Keep soil moist but not waterlogged
- Maintain a temperature of 65-70°F (18-21°C)
- Germination should occur in 2-4 weeks
Caring for Seedlings
Once your seeds have germinated, follow these care instructions:
- Provide bright, indirect light
- Keep soil consistently moist
- Fertilize with a diluted, balanced fertilizer every 2-3 weeks
- When seedlings have several true leaves, transplant to individual pots
Transplanting to the Garden
When seedlings are about 4-6 inches tall and outdoor temperatures are consistently above 50°F (10°C), they can be transplanted to the garden.
Transplanting Tips:
- Choose a location with full sun to partial shade
- Ensure well-draining soil
- Space plants 12-18 inches apart
- Water thoroughly after planting
Ongoing Care
To keep your Euphorbia corollata thriving, follow these care instructions:

Potential Problems and Solutions
While Euphorbia corollata is generally hardy, watch out for these issues:
- Root rot: Ensure well-draining soil and avoid overwatering
