2. Thinning treatment: Thinning treatment mainly starts from the base, which can cut off the branches of pests and diseases and focus on destruction, or cut off the branches that affect the appearance in time. Overlapping branches and parallel branches should be drained, and long branches, upright branches and drooping branches on the main branches should be cut off to increase the light transmittance in the crown and accelerate the formation of plants.
3. Shortening treatment: In plastic surgery, redundant dense branches can be cut off, and the remaining branches can be shortened to promote bud germination. When new buds germinate, the first cutting treatment can increase the number of modeling branches, and the length of the cutting section is about 5 cm, so it is not advisable to trim too much to avoid affecting the appearance.
4. Pruning: Pruning mainly refers to pruning perennial branches, which can promote the growth of new branches of Podocarpus, restore tree vigor, and timely prune tree species with large plant types to facilitate the modeling of bonsai. For those Podocarpus with strong germination, the amount of pruning can be appropriately increased, and only the main branches need to be reserved to facilitate the germination of new branches.
