PHASE 1 — POT CULTURE (UNDER COVER)
Objective: ensure maximum rooting success, protect plants from frost, and achieve uniform sprouting.
1) Rehydration (mandatory)
Before planting:
- Soak the root cuttings in clean water for 5 minutes.
→ This reactivates the tissues and improves the success rate.
⚠️ Do not exceed 5 minutes.
2) Start Period
- Early spring
- Ideal temperature: 15–25 °C (59–77 °F)
- Under a greenhouse, tunnel, or bright sheltered area
3) Pot Planting
Use individual pots for optimal root development and uniform emergence.
✔️ Root orientation
- Place the thicker end upward (bud side).
- Insert the root slightly angled (20–30°)
→ Promotes activation of the upper buds.
✔️ Covering
- Cover the root with no more than 1 cm of substrate.
(Buds must remain close to the surface.)
4) Recommended Substrate
A heavy substrate slows down emergence. A light, airy mix ensures faster and stronger sprouting.
Use:
- Fine horticultural potting mix
- Light, well-draining substrate
-
Optional: perlite for extra aeration
‼️ Paulownia does not tolerate excess water.
5) Watering (pot phase)
- Water moderately after planting.
- Keep the substrate slightly and consistently moist.
- Never waterlog the pot.
- Avoid all standing water.
6) Sprout Emergence
Timing depends on temperature and conditions:
- Sprouting usually occurs 3 to 8 weeks after planting.
- Faster in warm and stable environments.
In case of cold weather or late frost:
→ Cover pots with frost protection fleece.
