Artificial propagation: Cypress is usually propagated by cuttings, layering or grafting.

Cutting: The best time is April to May in spring. The cuttings should be 1 to 2 years old twigs, which are preferably semi-lignified. The cuttings are 12 to 18 centimeters long. Cut off the branches and leaves below the middle and the upper ends of the branches and leaves that are too dense. It can be thinned appropriately and the insertion depth is 1B3. The seedbed site should be high, dry, fertile, loose, and well-drained sandy soil. The soil should be loosened and raked before planting. After planting, water it thoroughly and put up a shed to provide shade. It will take about 8 months to take root. During this period, as long as the leaves do not turn yellow and fall off, they must be carefully managed. Spray water frequently in summer. After survival, transplant the seedlings in the second spring to cultivate large seedlings.

Layering propagation: It can be carried out all year round, but the best time is March to April in spring. For layering, branches with a diameter of 1 to 1.5 cm can be used, girdling and cutting, reaching the xylem, burying the branches in the soil, cultivating and compacting them, and managing and maintaining them carefully. Generally, roots can be formed 3 to 4 months after pressing.

Grafting propagation: It is mostly carried out by the docking method. Choose juniper or arborvitae seedlings as rootstocks. The trunk diameter of the rootstock should be 1.5 cm. The scion should be 2-year-old branches that are fully grown and still green. The docking time should be carried out in May. After about 2 months, the scion will be cut off from below the interface. When replanting in the spring of the second year, the rootstock seedlings above the interface will be cut off. Pot selection: Purple clay pottery pots are suitable for green cypresses. The pot shapes can be shallow or medium-deep rectangular, square, oval, round, etc.; large bonsais can use deep manger pots or deep round pots. The pot color is preferably dark ocher, purple sand and other dark colors to make the cypress bonsai look more simple, natural and green.

Soil used: Cuiper is not strict with soil and can tolerate mild acid and alkali. Potted plants commonly use mature pastoral soil or leaf mold soil mixed with 20% chaff ash or sand.

Planting: It should be carried out from March to April in spring, but also in autumn. Before planting, pay attention to using broken tiles to pad the bottom of the pot, and spread a layer of vermiculite or peat soil to facilitate water penetration. After planting in the pot, water it thoroughly once, and then wait for the soil to dry before watering again. Processing: The main processing of cypress is climbing, supplemented by pruning. Brown wire or metal wire can be used for climbing. The branches of cypress are soft and tough, easy to process, and can be bent and shaped at will. Focus on climbing the main branches well, and use brown silk to climb the small branches. After the cypress is formed, the side branches are mostly in the shape of spherical clusters. Therefore, when processing, pay attention to the gap distance between the upper and lower branches and leaves, and do not overcrowd them, causing a sense of occlusion. . With proper maintenance and management, cypress grows quickly and needs to be loosened and reshaped every 1 to 2 years.

Crystal cypress can also use part of its branches to make dry trunks to imitate the phenomena of natural trees that have been struck by wind, rain and lightning for a long time, resulting in some branches being broken and bark peeling off, resulting in an ancient and strange appearance. Effect. For example, there is a pot of cypress bonsai in Wenzhou Bonsai Garden. A dead branch stretches out from the green canopy, curling upward, giving people the feeling of tenacious struggle after thousands of years.

Tree shape: Cypress has strong plasticity and is suitable for processing into various tree shapes. Common ones include straight stem type, slanting stem type, curved stem type, waterfront type, three-table type, etc. The tree shape should avoid being artificial, stiff and dull, and it is better to be naturally vigorous, simple and vigorous. The main trunk must be naturally curved. Pay attention to the direction of the bend and the change in the degree of bending, so that there are connections and changes between the upper branches and the lower branches, the left branches and the right branches, and there must be a blank space. They cannot overlap one above the other and are connected in parallel. The shape of the tree reflects the beauty of elegance, elegance and simplicity.
