#### **8. Transplanting (for sowing in pots)**:
- **When to transplant**:
- When the young plants are about **10 cm** tall and have several well-developed leaves.
- **Method** :
- Transplant into individual pots or directly into open ground, respecting a spacing of **1 to 2 meters**.

#### **9. Final Planting:**
1. **Location**:
- Choose a spot in full sun with well-drained, nutrient-poor soil.
2. **Spacing**:
- Leave **1 to 2 meters** between plants to allow them to develop properly.
