How to grow iron walnut
2. Dig a hole 30 cm deep on the planting hole and plant the seedlings in the middle of the hole. The depth is based on the buried depth of the original seedling. When backfilling, gently lift the seedlings to make the roots of the seedlings stretch, fill and step on them. Repair the tree tray and water it immediately after planting. After the water permeates, cover the tree tray with a layer of soil to keep the water.
3. Walnut trees planted in autumn should be cut off and buried underground for cold protection before freezing, which is an important measure to improve the survival rate. Cut off the planted seedlings from the place 30 cm above the ground (without considering finding the whole bud, there are many adventitious buds and latent buds of walnuts, which are different from other fruit trees), and make a mound to bury the seedlings after cutting.
