Description

Our fully mature Manchurian ash seeds have full grains and stable germination vigor. Fraxinus mandshurica, also called Manchurian white ash, is a precious native broad-leaved deciduous arbor in Northeast China with extremely strong cold resistance and high economic value. It has pinnate compound leaves that turn bright yellow in autumn, straight and tall trunk, hard and tough wood, which is top-grade material for furniture, flooring and craftwork.

The tree features deep root system, excellent wind resistance, soil consolidation and barren tolerance, suitable for large-scale mountain afforestation. Seedlings grow steadily, and seed-grown trees can blossom and bear winged samara fruits after 6–7 years. Widely applied for northern shelterbelts, barren mountain ecological restoration, park landscape tree collocation, courtyard shade tree planting and precious timber forest construction. It prefers deep, fertile, loose and well-drained loamy soil; waterlogged low-lying land, heavy clay and stagnant water environment must be strictly avoided to prevent root rot and seedling death. Daily maintenance focuses on full sunlight, timely drainage and annual pruning to cultivate straight main trunk, a rare dual-purpose tree for landscape viewing and high-value timber.

Planting Instructions

Soil Preparation
Mix deep garden topsoil, coarse river sand and decomposed organic fertilizer to form loose breathable planting substrate. Raise seedbeds for field sowing to guarantee smooth drainage and eliminate accumulated rainwater. Avoid overly compacted sticky soil with poor permeability.
Seed Pre-treatment
Manchurian ash seeds have strong deep dormancy, cold moist sand stratification is the core step. Remove seed wings and impurities first, soak in warm water for 48 hours, then carry out 90–120 days low-temperature sand storage at 2–5°C. Sow in spring when a large number of seeds show tiny cracks. Without long-term stratification, germination rate will be extremely low.
Sowing Method
Adopt strip sowing on seedbeds, bury treated seeds 2–3 cm deep into moist soil, cover thin fine soil and slightly compact the surface. Row spacing 30 cm, seed spacing 8–10 cm. Direct seeding is recommended; transplant saplings with complete soil balls to reduce root damage and improve survival rate.
Germination Condition
Keep substrate slightly humid without standing water, optimal germination temperature 16–26°C. Concentrated germination occurs within 30–50 days after sowing. Cover breathable plastic film before seedling emergence to retain temperature and humidity, remove covering timely after sprouting.
Daily Maintenance
Place ash seedlings under full sunlight all year round; long-term shade will cause slender trunks, weak growth and delayed fruiting. Reduce watering frequency greatly in rainy seasons to prevent root rot and damping-off disease. Thin dense seedlings when height reaches 12 cm, trim competing lateral branches every year to keep upright main trunk. Apply diluted organic fertilizer once in late spring to boost sapling growth speed.

FAQ

Q1: Can Manchurian ash survive severe cold in Northeast China?

A1: Yes, it can resist minus 42°C extreme low temperature and safely overwinter in open ground in most frigid northern areas.

Q2: Why is long-time cold stratification necessary?

A2: The seed embryo has deep physiological dormancy, 3–4 months low-temperature sand storage is required to break dormancy for normal germination.

Q3: What light condition does it need?

A3: Full direct sunlight is required. Shaded environment leads to slow growth, curved trunks and poor autumn leaf color.

Q4: Main planting prohibitions?

A4: Long-term waterlogging causes irreversible root rot; insufficient dormancy breaking results in almost no germination.

Q5: Suitable for beginners?

A5: Suitable for patient growers. The key operation is long-term low-temperature sand stratification before sowing, matched with well-drained fertile soil and full sunlight environment.
