How to plant Fraxinus seedlings
If you want to learn how to plant Fraxinus seeds and related knowledge about the cultivation techniques of Fraxinus trees, let's take a look together!
Fraxinus seeds have a long dormancy period, and pre-germination is required for spring sowing. There are methods such as low-temperature stratification pre-germination and rapid high-temperature pre-germination.
Method/Steps
1/3 Step-by-step reading
Select a high ground with good drainage, leeward and shaded area to dig a trench. The depth of the trench should be below the frost line and above the groundwater level. The width of the trench is 80 cm, and the length depends on the amount of seeds. The ratio of Fraxinus seeds to wet sand is 1:2-3. First, lay a 10 cm thick layer of wet sand at the bottom of the trench, then mix the seeds and wet sand thoroughly, place them in the trench, and the thickness of the seed-sand mixture is 50-70 cm. Cover with a 10 cm thick layer of wet sand 10 cm from the ground, then cover with soil to form a ridged top. Place a corn stalk every 0.7-1 m for ventilation, usually for 60-80 days.

Seeds that have not undergone low-temperature stratification pre-germination in winter can be soaked in 40°C warm water, naturally cooled, and then soaked for 2-3 days, changing the water once a day. Take out the seeds and mix them with three times the amount of wet sand, place them on a warm bed for germination. The temperature should be maintained between 20-25°C, turn them over every day, keep them moist, and when the sum of seeds with emerging radicles and cracked mouths reaches 30% of the total number of seeds, they can be sown.

Choose sandy loam soil that is loose and fertile with convenient irrigation and drainage. Prepare the land carefully before sowing, making it flat, loose, uniform, and fine. For sandy or clayey soil, take effective soil improvement measures, such as applying a lot of organic fertilizers, mixing a large amount of sand or importing soil to improve the physical and chemical properties of the soil. Apply 2-3 kg of 5% phoxim granules per 667m2, mix the medicine with fine soil, spread it in the nursery, then plow the soil to eliminate underground pests. Apply 15-20 kg of ferrous sulfate per 667m2, mix it with 20 times the amount of fine soil, and evenly spread it in the seedbed to prevent seedling damping-off disease.
The above is an introduction to how to plant Fraxinus seeds and related cultivation techniques for Fraxinus trees, which can be used as a reference suggestion for everyone.
