How to plant wenwan walnuts

1. Sowing

In mid-March, soak the seeds in cold water for 2—3 days, then remove them and mix them with wet sand, piling them in a sunny spot. Make the pile 30—35cm high, cover it with l0cm of wet sand on top, sprinkle water once a day to keep it moist, and cover it with a straw curtain or plastic film at night to retain moisture and warmth. After 10—15 days, once the shells crack and the white sprouts show, they are ready for sowing. Select once a day and sow in batches, and sow with sufficient soil moisture. First open furrows at a row spacing of 40—50cm, and sow at a plant spacing of 15—20cm, placing the two suture lines parallel to the ground, with a depth such that the fruit is 3-5cm from the soil surface, then cover with soil and press firm to preserve moisture.

2. Grafting

Grafting is carried out from late March to early April. First collect the scions: in mid-March, when the buds are about to sprout, collect 1-year-old branches that are vigorous and free of pests and diseases as scions, store them by variety in wet sand after collection, and begin grafting in early April once the buds of the walnut rootstock start to sprout. Within 12 hours before grafting, make a cut at the root collar down to the xylem to “bleed” the tree, then carry out cleft grafting or bark grafting; after grafting, tie the wound tightly with plastic strips, and coat the upper end of the scion with paint to prevent water loss. After survival, promptly remove sprouts and loosen the ties, and the best time to loosen them is when the new shoots have grown more than 20cm. When the grafted seedlings have grown to about 40cm, fix them with small bamboo poles or wooden sticks to prevent wind breakage.

3. Management

The planting time is around budding in late March; planting 1-2-year-old seedlings gives a high survival rate. After planting, water thoroughly, strengthen water and fertilizer management, frequently loosen the soil and weed, pay attention to drainage in the rainy season, and pay attention to pest and disease control in June-July. During the growing period, pruning should be carried out, keeping the trunk height above 3m. Do not prune after leaf fall, otherwise it easily causes bleeding, affecting the tree's growth.
