Second, the causes and solutions of the yellowing of bamboo and cypress leaves.

1. Environmental discomfort

To talk about the reason why the leaves of bamboo and cypress turn yellow, we should first think about the environment. Nowadays, many of the potted plants of flower friends are bought online, which can easily lead to large geographical cross-clothing, great changes in the environment, and the emergence of yellow leaves because the plants can not adapt for a while.

Solution: move the bamboo and cypress to a shady place in time for maintenance, and after it slows down, water it appropriately.

② temperature is too low: bamboo and cypress are not cold-resistant. When the winter temperature is lower than 10 ℃, it will enter the dormant period. When the temperature is lower than 2 ℃, bamboo and cypress are prone to frostbite, resulting in yellow leaves. Solution: move the bamboo and cypress to a warmer place indoors, adjust the temperature to more than 10 ℃, and the plant will soon return to health.

6. Diseases and insect pests

In indoor culture of bamboo and cypress, due to poor environment, improper maintenance and other reasons, plant leaves are prone to red spiders, shell insects, anthracnose, leaf spot and other diseases and insect pests, which will cause local scorched yellow leaves.

Solution: we only need to identify specific diseases and insect pests, and then spray them. As for what kind of medicine to spray, you can refer to the pest control of bamboo and cypress.

Generally speaking, the breeding method of bamboo and cypress is not difficult, but it does not mean that it can be raised casually.

2. Pruning: when the plant enters the dormant or semi-dormant period in winter, the branches such as thin, disease and insect, withered and overdense should be cut off. The branches can also be arranged in combination with cuttings.

3. Change the basin: as long as it is properly maintained, it will grow very fast. when it grows to a certain size, it should be considered to change a larger basin to allow it to continue to grow vigorously.

4. Take off the basin: put the flowers that want to change the pot on the ground, first pat the four sides of the basin with a slap, so that the root system is shaken and separated from the basin wall, put the flowerpot upside down on the left hand, gently clamp the plant with the index finger and middle finger of the left hand, hold the edge of the basin with the wrist and fingertip, hit the bottom of the basin with the right hand, and then use the mother finger to top the root soil down from the bottom hole to let the plant out.

Matters needing attention of bamboo and cypress

1. Bamboo and cypresses are curved when they are first unearthed, growing stems first and then leaves. The unearthed rhizomes are easy to be infected by fungi, because methyl carbendazim and carbendazim are sprayed alternately, weeds should be weeded frequently in seedling stage, bamboo and cypress sprouts are tender, water and fertilizer management should be strengthened and watered at regular intervals.

2. Bamboo and cypress trees grow slowly, so they are first planted in a nutrition bowl, and a year later, when the buds have one leaf and two hearts, they can be transplanted into the field. Phyllostachys pubescens is a straight-root plant with well-developed main roots because cutting off the main roots is beneficial to the growth of lateral roots.
