For bare-rooted tree seedlings, the planting depth should be 5-10cm deep from the original root neck soil mark. For shrubs, the planting depth should be level with the original soil roots. Bamboos can be 5-10cm deeper than the original planting depth. The depth of planting seedlings with soil balls should be 2 to 3 cm deeper than the top of the soil balls. In the process of planting trees with soil balls, the packaging that is not suitable for decay should be removed to prevent trees from being polluted. After the trees are planted and the irrigation weirs are built, the grass ropes at the canopy of the trees should be untied to let them grow. Some precious trees should be sprayed on the crown after planting, and measures such as moisturizing the trunk and spraying some rooting hormones on the trunk can also be taken. For some planting holes with poor drainage, a layer of 10cm gravel or a seepage pipe can be laid on the bottom. If planting between rockeries or rock peaks, some moisturizing and breathable materials should be added to the planting soil.
