2. Bonsai is made by sowing or cutting propagation, but it takes a long time to cultivate, so it is difficult to get good materials by paws and vitality alone. The second is to dig old piles. Old piles are excavated in summer, followed by spring and autumn, and winter is the worst. After excavation, the pile blank can be wrapped in plastic bags to keep the roots moist. When planting, remove the descending taproots and cut off most leaves to prevent water loss and ensure survival. You can raise the blank in the open field first, or you can raise it directly in a pot, but it must be cultivated for more than two years before it can be made.
3. Choose Yixing purple sand basin or light glazed pottery basin. The shape and size of the basin can be determined according to the size and modeling form of the pile. In principle, the cliff type should adopt square or round thousand-barrel basins, inclined drying, bending drying and jungle basins, round, oval and rectangular basins.
4. Potted soil Buxus microphylla likes fertile sandy loam. Potted soil is fertile and loose sandy loam with good ventilation and water permeability. It can also be mixed with 40% slag, 40% humus soil or garden soil and 20% river sand.
5. The best time to go to the basin is between spring and summer. When planting, the roots that are too long and too dense should be trimmed off, and the roots can be modified according to the needs of modeling, so that the roots can naturally stretch in the basin. Don't plant too deep. After the soil is covered with water, place it in a semi-shady place, keep the soil moist, and often spray water on the leaves. After about 30 days of plant growth, it can be transferred to normal maintenance.
6, modeling should be based on the basic tree of plants, let nature take its course, artistic modeling. Modelling technique can be cut and bound, but it is best to climb in summer and autumn, when the branches are more flexible and easy to bend; Pruning should be done in spring. Buxus microphylla has strong germination ability, but "it will not germinate without leaves" Therefore, whether it is modeling or daily pruning, we can adopt the method of "keeping leaves step by step and cutting short to promote buds" to let them sprout step by step, and don't blindly pursue one step.
7. Maintenance and management Buxus microphylla likes to be wet and needs to be watered frequently. May-August is the vigorous growth period of Buxus buxus, and thin decomposed cake fertilizer can be applied in stages in combination with watering. Always pay attention to pruning long branches, overlapping branches and redundant branches that affect the tree potential. The fruits of Buxus microphylla should be picked in time to avoid consuming nutrients. Generally, the time for changing the pots of Euonymus japonicus is 2-3 years for medium and small pots, and 5 years for large pots. Plants with weak growth should be turned over in time. Combined with changing pots, cut off some old roots that are too long and too dense, and replace them with new culture soil for replanting.
