Ulmus Campestris Seeds, Field Elm

Sowing **Ulmus** (elm) seeds is relatively simple and can produce good results if you follow the proper steps. Elm seeds are usually light and surrounded by a thin membrane (samaras). Here's how to do it:

### **Steps for sowing Ulmus seeds:**




#### **1. Soil preparation:**
- Use a light, well-drained substrate, composed of seedling compost mixed with a little sand.
- If you are sowing in open ground, loosen the soil and make sure it is well drained.

---

#### **2. Sowing seeds:**
- **Indoors (in pots)**:
- Fill a tray or pots with the prepared substrate.
- Sow the seeds on the surface, as they need light to germinate.
- Lightly cover the seeds with a very thin layer of substrate or leave them uncovered.
- Water gently to moisten the substrate without soaking it.

- **Outdoors**:
- Sow seeds directly onto a prepared seedbed.
- Lightly press the seeds into the soil to ensure good contact with the substrate.

#### **3. Germination conditions:**
- **Light**: Place the pots in a bright place, but away from direct sunlight.
- **Temperature**: Ulmus seeds germinate well at a temperature between **15°C and 25°C**.
- **Humidity**: Keep the substrate slightly moist until germination. Avoid letting it dry out completely.

---

#### **4. Germination and care of seedlings:**
- Ulmus seed germination is rapid, often within **7 to 14 days** after sowing.
- When the seedlings reach about **5 to 10 cm** in height, thin them out to leave the most vigorous ones if you have sown densely.
- Transplant the young plants into individual pots or directly into the ground once they have reached a sufficient size and all risk of frost has passed.

---

#### **5. Outdoor planting:**
- When the young plants are about **15 to 20 cm**, you can transplant them into the ground.
- Choose a sunny location with rich, well-drained soil.
- Leave enough space between the plants to allow them to develop fully (3 to 5 meters between each tree depending on the species).

### **Additional Tips:**
1. **Protection against pests and diseases**: Elms are susceptible to certain diseases such as Dutch elm disease. It is important to monitor young trees and choose resistant species or cultivars if possible.
2. **Watering**: Young plants require regular watering, especially during dry periods.
3. **Fast Growing**: Elms are generally fast growing and can reach several meters in a few years.

### **Conclusion :**
With a light substrate, constant humidity and good exposure to light, you can successfully grow young elms in a short time. 🌱
