Paulownia Elongata – Premium Bare Root Cuttings (Pure Species)

Paulownia elongata is a pure species within the Paulowniaceae family, renowned for being one of the fastest-growing hardwood trees in global forestry. Native to Asia and cultivated extensively across China, North America, and Europe, this species is highly valued for its rapid height development, light yet durable timber, and remarkable biomass production capacity.

Thanks to its vigorous growth and adaptability, Paulownia elongata is widely planted for forestry projects, timber production, biofuel feedstock, reforestation, and sustainable biomass energy systems. Its ability to reach harvestable size in only 5–7 years makes it one of the most productive hardwood species for environmentally responsible plantations.

Each root cutting from GreenSeed Paulownia is premium Grade A, selected for optimal thickness, health, and vitality. These roots are conditioned for spring planting, providing fast establishment and consistent early performance across a wide range of climates.

⭐ Key Characteristics

Pure species (non-hybrid): valued for natural vigor, strong wood quality, and ecological benefits.
Ultra-fast growth: reaches 3–5 meters in the first year under optimal conditions.
Short rotation forestry: can reach harvestable size in 5–7 years, ideal for rapid-rotation timber projects.
High-quality wood: produces light, durable, and stable timber used for furniture, plywood, veneer, carpentry, and biofuel production.
Strong biomass potential: generates large annual biomass yields, making it an excellent choice for renewable energy and sustainable fuel production.
Moderate cold tolerance: withstands –15 to –20 °C, suitable for warmer temperate climates and zone 6–9 regions.
Ornamental value: large leaves and beautiful lavender-white flowers appearing in spring and early summer.
Versatile ecological role: contributes to reforestation, soil improvement, and carbon sequestration.

Required Materials

Fine, sterile seed-starting mix (peat/coco + perlite), light and well-draining
Seed trays, small pots, or a mini-greenhouse
Fine mist sprayer or watering can with a soft rose
Clear lid, plastic film, or humidity dome
Thermometer or heat mat to maintain 20–25 °C (68–77 °F)
Bright growing area or horticultural LED light (PPFD 100–250 μmol/m²/s)

1) Stratification (Cold Treatment)

Optional but recommended to achieve uniform germination.

Mix the seeds with a slightly moist substrate (fine sand, vermiculite, or light seed mix).
Place the mixture in an airtight bag or sealed container.
Refrigerate at about 4 °C (39 °F) for 4–12 weeks.

2) Sowing

Fill containers with pre-moistened substrate (moist but not waterlogged).
Scatter the seeds on the surface — do not cover; they need light to germinate.
Mist gently with water.
Cover with a clear lid or humidity dome.
For large-scale production, use a misting chamber or heated propagation bench.

3) Germination Conditions

Temperature: 20–25 °C (68–77 °F), stable
Light: bright indirect light or LED grow lighting
Duration: usually 10–20 days
Substrate: always slightly moist, never waterlogged
Ventilation: avoid cold drafts but ensure minimal air exchange

4) After Germination (Critical Phase)

Open the lid slightly each day to reduce excess humidity.
Gradually increase ventilation to strengthen stems.
Remove the cover completely once seedlings have 1–2 true leaves.
Maintain strong light to prevent weak, elongated seedlings.

5) Transplanting & Early Growth

Transplant when seedlings reach 10–15 cm (4–6 in) or show 2–3 true leaves.
Use individual pots (7–10 cm) for optimal root development.
Keep plants in bright shade for 3–5 days after transplanting, then gradually expose them to full sun over 1–2 weeks.
Water moderately: avoid both drought and excess moisture.
Optional for production: apply a light, balanced fertilizer after 3–4 weeks (e.g. NPK 10-10-10).

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.
