Paulownia Hybrid 9502 – Premium Bare Root Cuttings (Grade A)
The Paulownia Hybrid 9502 is an enhanced selection within the renowned 950x hybrid lineage, developed to deliver greater uniformity, superior timber quality, and improved plantation stability.
Created from the cross Paulownia fortunei × Paulownia tomentosa, this hybrid was designed specifically to outperform the earlier 9501 selection by offering more consistent growth, straighter trunk formation, and better overall productivity.
Recognised by professional growers and forestry specialists, the 9502 hybrid has earned its reputation as a highly reliable and stable performer, particularly valued in large-scale timber production, reforestation programs, and commercial planting projects that demand predictable results and homogeneous tree development.
Each bare root cutting supplied by GreenSeed Paulownia is premium Grade A, carefully selected for health, thickness, and rooting potential. Roots are conditioned for spring planting, ensuring excellent establishment and vigorous early growth, even in challenging climates.
⭐ Key Characteristics
-
Improved 9501 selection: refined genetics providing superior homogeneity and enhanced structural stability across plantations.
-
Uniform and predictable growth: ideal for large forestry operations requiring consistent trunk diameter and height development.
-
High-quality timber: produces denser, straighter, and more uniform wood, widely used for plywood, veneer, carpentry, and high-value furniture production.
-
Cold-resistant hybrid: tested to withstand –25 °C, making it reliable in a wide range of temperate climates.
-
Strong adaptability: thrives in well-drained soils and performs well under full sun exposure.
-
Professional-grade hybrid: valued for its consistency, reliability, and improved performance compared to earlier 950x selections such as 9501.
-
Excellent environmental performance: contributes significantly to CO₂ absorption and sustainable forestry objectives.

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.
