### Steps for sowing:

#### 1. **Seed harvest and preparation**:
- The seeds are in woody pods and are covered with a fibrous husk. Remove this husk before sowing to avoid skin irritation.
- Clean the seeds to remove any residue.

#### 2. **Soaking the seeds**:
- Soak the seeds in warm water (about **50-60°C**) for **24 hours**. This softens the hard shell of the seeds and improves their ability to germinate.

#### 3. **Scarification (optional but recommended)**:
- If soaking has not been enough to soften the shell, lightly scarify the seeds by rubbing their surface with sandpaper or by lightly cutting the shell with a knife. Be careful not to damage the embryo.

#### 4. **Substrate preparation**:
- Mix lightweight potting soil with an equal part of sand or perlite to ensure good drainage.
- Fill your pots or seed trays with this mixture.

#### 5. **Sowing the seeds**:
- Plant the seeds at a depth of **1 to 2 cm** in the substrate.
- Cover them lightly with a thin layer of sieved substrate.
- Tamp gently to ensure good contact with the soil.

#### 6. **Watering**:
- Lightly moisten the substrate with a spray bottle or a low-flow watering can.
- Maintain constant humidity, but avoid soaking the soil.

#### 7. **Germination conditions**:
- Place the pots in a warm, bright place, away from direct sunlight.
- The ideal temperature for germination is **25 to 30 °C**.
- Use a mini greenhouse or a transparent plastic bag to retain humidity and heat. Ventilate regularly to avoid mold.

#### 8. **Germination**:
- Seeds usually germinate in **2-6 weeks**, but it may take longer depending on conditions.

#### 9. **Replanting**:
- When the seedlings reach about **10 cm** in height and develop several leaves, transplant them into individual pots.
- Use a similar substrate and place the pots in a bright but protected place.

#### 10. **Planting in open ground**:
- Transplant the young plants into their final location after **6 to 12 months**, when the plants are robust.
- Choose a sunny location with well-drained soil.
