How to plant Lagerstroemia indica 60 cm?

Is it 60 cm in diameter? No way! Its diameter may be six centimeters. Transplanting method: dig a pit with a depth of 80 cm and a square of 1 m, fill the bottom with 15 cm-25 cm fermentation base fertilizer, and then fill with 10 cm mature soil, then put the tree in the middle, step on it while filling, and pay attention to the stretching of the roots, and don't curl. You can lift the tree and let its roots stretch. The planting depth of Lagerstroemia indica should be the same as that of the original plant. You can pull the rope on three sides to fix the trees against the wind. Then water it, and then water it after 3 days until it survives. In order to ensure survival, you can cut off the branches of most trees.
