1, basin soil
Buxus microphylla is a shallow-rooted plant. Try to choose a pot with a big mouth and a shallow depth. It is generally recommended to choose purple clay pots. Buxus microphylla has low requirements on soil and strong alkali resistance. Of course, it is best to use loose and fertile sandy loam for planting, and vermiculite, peat or garden soil can also be used for potted plants.
water
Buxus microphylla bonsai should keep the soil moist. Buxus microphylla needs a lot of water in the whole growth process, so it can be watered when the soil is slightly dry. In addition, watering times should be increased or decreased according to seasonal climate change. When the temperature is high in summer, the watering frequency can be increased appropriately, and less watering should be done in winter dormancy period.
Step 3 apply fertilizer
Buxus microphylla can often be sprayed with some foliar fertilizers, such as dilute nitrogen fertilizer, during the growth period. Organic fertilizer can be applied to the pot every month, but immature fertilizer and excessive fertilizer cannot be used. Seasonal fertilizer can be applied before seasonal changes, such as accelerating germination in spring, strengthening foliar fertilizer in summer, applying some fertilizer after pruning, and adding a small amount of nitrogen fertilizer when watering at ordinary times.
prune
The trunk of boxwood bonsai grows slowly, but the twigs grow fast. Too dense branches and leaves will make the whole bonsai messy, so do a good job of pruning. Before the branches are lignified, one or two pairs of young leaves can be left, and the rest can be cut off until the new buds grow. Slowly, the branches will thicken, so it is necessary to trim the branches and leaves regularly to improve the ornamental value.
5. Panza
When winding, avoid the phenomenon of broken branches. Generally, aluminum wire or copper wire is used for winding. Beginners can try to start with sketch modeling and use rubber-coated metal wires for winding modeling to avoid damage to branches. According to the thickness of the trunk, choose a suitable metal wire for winding, and the size of the metal wire is about 1/3 of the thickness of the root of the winding branch. Winding should be done from bottom to top, from coarse to fine. When winding the trunk, a metal wire should be inserted into the soil near the trunk and fixed before winding. When winding the wire, pay attention to the cooperation between the wire and the bark to avoid being too tight or too loose. When the main branch and the side branch are knotted, it can be operated in a shoulder-to-shoulder manner, and the middle section of the metal wire is wound on the two adjacent branches respectively, so as to avoid finding the fixed point and failing to achieve the expected purpose.
Step 6 change the pot
The best time to change pots is early spring. Prune the root system of Buxus microphylla when changing pots, because the root system of Buxus microphylla is fine. If the root is long, it can't stretch in time after changing pots, and bending is very unfavorable to the potted growth of Buxus microphylla. Therefore, long roots, dead roots, diseased roots and chaotic roots should be trimmed when changing pots. After changing the basin, it can be placed in a cool and ventilated environment for normal maintenance.
