Walnut tree has a new way to prevent cold

Soil protection against cold in the base of seedlings within 30 cm to cultivate a mound, to prevent frostbite neck and graft interface. After the spring temperature has risen and stabilized in the spring of next year, it will be removed and the tree plate will be leveled.

To protect the exposed 1-2 year-old saplings that cannot be safely overwintered in open fields, the entire tree body is bent to one side, covered with soil, and sprayed with new high-fat membrane insulation and larvae. This method is the most effective and reliable measure for preventing and controlling pumping.

White coated cold-resistant sapling can alleviate the temperature difference between the yin and yang surface of the trunk. The formulation of the whitening agent is: use the “General Tree Guard”, salt 0.5 kg, quick lime 6 kg, clear water 15 kg, and then add the appropriate amount of adhesive and stone The residue of the sulphur mixture is spread over the young branches. Smear before soil freezing, better cold resistance.
