Before planting the shaped landscape pines, they are pruned to reduce water loss, ensuring a balanced tree condition for survival. The amount of pruning varies depending on the species, with generally minimal trimming for evergreen conifers and hedges used for planting, focusing only on removing dead, diseased, or injured branches.

      For larger landscape pines with distinctive shapes, heavy pruning is recommended. This can alleviate the root load, maintain the water balance within the tree, and ensure the tree is stable after planting, preventing wind sway. Pay attention to the height of the branch points during pruning. When pruning shrubs, maintain their natural tree shape, ensuring that the cut should be lower on the outside and higher on the inside. Before planting shaped oil pines, proper root pruning should also be conducted, primarily involving the removal of broken, split, and overly long roots. Ensure that the pruning cuts are flat and smooth, and promptly apply a preservative to prevent excessive evaporation, drought, freezing, and pest damage.

      The planting method for shaped landscape pines is as follows: Place the soil ball or root ball of the shaped landscape pine into the planting hole, ensuring it is centered; then, stand up the trunk and straighten it to maintain a vertical position; next, backfill with planting soil in layers, slightly lifting the roots upwards after each layer to allow the root system to spread out. After backfilling, use a hoe to compact the soil layer by layer until the hole is filled, and the soil surface should cover the tree's root collar. After the initial planting, check if the trunk remains vertical and if the crown is tilted; if it is, adjust it further. Surround the root collar with the remaining soil to create a ring-shaped water retention dike. The diameter of the dike should be slightly larger than the diameter of the planting hole. The soil in the dike should be compacted tightly and not be loose. Free thesis.
