True cypress bonsai is famous for its old stems, dense leaves and quaint tree appearance. Especially in Japanese bonsai exhibitions, the "relic stem" made of a hundred-year-old cypress, with white bones and red skins, is like Youlong, vigorous and simple, and it is the best in bonsai. Then, some flower friends asked that such a precious real cypress bonsai must be difficult to maintain. To be honest, for flower friends who don't pursue the ultimate, real cypress bonsai is actually not difficult to maintain. How to maintain the true cypress bonsai

Generally speaking, the main cypress species used for bonsai production are: cypress, cypress, arborvitae, juniper, true cypress and ground cypress. Today, we will talk about how to maintain the bonsai of Zhenbai:

The growth habit of Zhenbai: it likes light, is slightly shade-tolerant, has strong cold resistance, and is also barren, and can be born in cracks in rocks; The requirements for soil are not strict, and both neutral soil and calcareous soil can adapt. However, fertile, deep and humus-rich soil is the most suitable. The following points should be paid attention to in the daily maintenance of the basically formed true cypress bonsai:

First, the light should be sufficient, but proper shading must be given in summer. In spring, summer and winter, it must be placed in a place with sufficient light to receive full light, so as to avoid dead branches and leaves in the chamber.

however, when the ambient temperature exceeds 3℃ in summer, it should be moved to a place with 2 ~//-3% shading, especially to avoid strong light exposure around noon, so as to avoid the water supply being difficult to reach the designated position in time under high temperature and strong light baking, which will lead to the necrosis of nutrient fibrous roots on the surface of the basin soil. As a result, some twigs and needles turn yellow and die; In addition, excessive high temperature and strong light will also lead to the loss of green and yellowing of leaves, and even burn leaves in severe cases.

second, the basin soil is always moist. According to the principle of "dry pine and wet cypress", it is necessary to maintain enough water in the basin soil during the growing season, not only to keep the basin soil in a wet state, but also to prevent water accumulation. When the ambient temperature is above 3℃, it is necessary to spray water on the crown and the surrounding area. If the pot soil is too dry, and it is in a high temperature or unventilated environment, it is easy to cause the needles and twigs to turn yellow and die.

third, timely topdressing. In the growing season, the decomposed thin cake can be watered once a month, and the pots can be turned over in early spring every year to keep the needles green and green.

fourth, timely pruning. Remove the delicate and dead branches in the inner chamber, and shrink and cut the excessive branches protruding from the crown to maintain a well-penetrated plant shape.

5. Turn the pots regularly. True cypress usually turns the pot every 2~3 years, and the time should be in March ~ April in spring or autumn. When turning the pot, the roots will be trimmed properly, and 1/3~1/2 of the old soil will be removed, replaced by fertile and loose humus soil, and mixed with appropriate amount of chaff ash (i.e. carbonized "persistent" rice husk ash, which is black) and sand.

six, disease prevention and control. In the hot and dry season, it is easy to be harmed by red spider, so it should be sprayed with 2 times solution of 259, Beileba wettable powder regularly to prevent the cypress needles from losing green and yellowing. In addition, attention should be paid to prevent bark beetles from harming the phloem of the trunk.
