### Steps for sowing:

#### 1. **Seed harvest and preparation**:
- If you harvested the seeds yourself, make sure they are completely dry.

#### 2. **Soaking the seeds**:
- Soak the seeds in warm water (about 30-40°C) for **24 hours**. This hydrates the seeds and stimulates germination.

#### 3. **Substrate preparation**:
- Prepare a light and rich substrate, composed of seedling compost, sand and well-decomposed compost, in equal parts.
- Fill your pots or seed trays with this mixture.

#### 4. **Sowing the seeds**:
- Sow the seeds at a depth of **1 to 2 cm** in the substrate.
- Cover them lightly with a thin layer of sieved substrate and gently tamp them down to secure them.

#### 5. **Watering**:
- Gently moisten the substrate with a spray bottle or a watering can at low flow.
- Keep the substrate constantly moist, but avoid soaking it.

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

#### 7. **Germination**:
- Bamboo seeds typically germinate in **10 to 30 days**, depending on conditions. Be patient, as germination can sometimes take longer.

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

#### 9. **Final planting**:
- Transplant the young plants into their final location after **6 to 12 months**, when the plants are robust.
- Choose a sunny location with rich, well-drained soil.
