Seeds of Paulownia Elongata, Emperor Tree

Sowing **Paulownia elongata**, just like **Paulownia fortunei**, can be very successful if specific steps are followed to ensure germination and optimal growth. Here are the detailed steps for successful sowing of **Paulownia elongata**:

### 1. **Seed Preparation**
- Paulownia elongata seeds are also small and lightweight, and like **Paulownia fortunei**, they usually require cold stratification to ensure successful germination.
- Place the seeds in a plastic bag with some damp sand and leave them in a refrigerator at about 4°C for 4 to 6 weeks. This simulates winter and encourages germination.

### 2. **Soil preparation**
- Paulownia elongata prefers well-drained, slightly acidic to neutral soil (pH 6 to 7). It is essential to avoid soil that is too compact or poorly drained, as stagnant moisture can hinder germination and root development.
- You can sow in pots with a light mixture of potting soil, sand, and perlite to promote aeration.

### 3. **Sowing**
- Sow the seeds on the surface, as they need light to germinate. Avoid covering them with soil.
- If you are sowing in pots or seed trays, be careful not to crowd the seeds too much, as they will need space to develop.
- You can also sow in open ground if you are in a favorable climate, but it is often better to start indoors or under cover for better control of conditions.

### 4. **Germination conditions**
- The ideal temperature for germination is around 20 to 25°C. It is important to maintain good humidity, but be careful not to overwater to avoid mold.
- Keep seedlings in a warm, bright place, but out of direct sunlight.
- Seeds can germinate in 2 to 4 weeks, depending on temperature and humidity conditions.

### 5. **Seedling Care**
- Once the seeds have germinated, it is important to maintain good air circulation around the young plants to avoid mold problems.
- Water regularly but lightly. Do not let water stagnate in the pots or on the ground.
- When the seedlings get bigger, you can start to provide them with more light, but always gradually.

### 6. **Transplanting and planting in open ground**
- Once the young plants have reached a sufficient size (about 10-15 cm in height), you can start transplanting them into open ground or larger pots.
- If transplanting into the ground, choose a sunny, well-drained location with room for the tree to grow. Be sure to space the plants at least 2-3 meters apart, as **Paulownia elongata** can grow to an impressive size.
- You can plant in spring or early summer when the risk of frost has passed.

### 7. **Care after planting**
- In summer, make sure to water regularly so that the young trees have the humidity they need to grow. However, be careful not to saturate the soil with water.
- Paulownia elongata is a fast growing tree and needs a good amount of sunlight to develop properly.
- You can also apply mulch around young plants to retain moisture and reduce competition with weeds.

### 8. **Growth Tracking**
- This tree species grows very quickly once established, so keep an eye on young plants, especially for diseases or pests.
- You can prune dead or misplaced branches to encourage better development of the tree structure.

By following these steps, you will promote the proper growth of **Paulownia elongata** and have good results in growing this fast-growing, large tree.
