True cypress bonsai how to maintain true cypress bonsai generally speaking, the main cypress species used for bonsai production are: Longbai, Cuibai, Platycladus orientalis, juniper, true cypress and Pudi cypress. Today, let's talk about how to maintain the bonsai of Zhenbai:
Growth habits of true cypress: light loving, slightly shade resistant, strong cold resistance, barren resistance, and can grow in rock cracks; The requirements for soil are not strict, and neutral soil and calcareous soil can adapt. However, fertile, deep and humus rich soil is the best. For the basically formed true cypress bonsai, the following points should be paid attention to in daily maintenance:
1、 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 inner chamber.
It should be placed in the place where the temperature of the nutrient pot is more than 30 ℃ before and after baking in summer, especially in the place where the temperature of the nutrient pot is more than 30 ℃, so as not to expose the root to the strong sunlight in time, so as to prevent it from entering the place where the temperature of the nutrient pot is more than 30 ℃. As a result, some twigs and needles turn yellow and die; In addition, excessive high temperature and strong light will also cause the leaf color to lose green and yellow, and burn the leaves in severe cases.
2、 Basin soil is always kept wet. According to the principle of "dry pine and wet cypress", maintain sufficient water in the basin soil in the growing season, not only keep the basin soil in a wet state, but also avoid ponding. When the ambient temperature is above 30 ℃, spray water on the canopy and around the tree. If the basin soil is too dry and is in a high temperature or unventilated environment, it is also easy to cause the needles and twigs to turn yellow and die.
3、 Timely topdressing. In the growing season, the rotten thin cake fertilizer and water can be watered once a month, and the pots and soil can be changed once a year in early spring to keep its conifers green.
4、 Trim in time. Remove the thin, weak and dead branches in the inner chamber, and shrink and shear the excessive branches protruding from the crown to maintain a well permeable plant shape.
5、 Turn the basin regularly. True cypress generally turns the basin every 2 ~ 3 years. The time should be from March to April in spring and autumn. When turning the pot, properly trim and tidy the roots, remove 1 / 3 ~ 1 / 2 of the old soil, replace it with fertile and loose rotten leaf soil, and mix an appropriate amount of rice husk ash (i.e. carbonized \ "stored \" rice husk ash, black) and sandy soil.
6、 Disease prevention and control are in place. In the hot and dry season, it is easy to suffer from red spider. Regularly spray it with 259,0 beileba wettable powder 2000 times liquid to prevent cypress needles from losing green and turning yellow. In addition, attention should be paid to prevent bark beetles from harming the phloem of dry branches.
