Culture methods and matters needing attention of Yushu how to prune Yushu

Yushu is a very common succulent plant, its leaves are relatively green and thick, very ornamental. At present, it is distributed in China's large and small flower market, and many people choose it when they choose to buy it. Yushu is also easy to shape, and it needs regular pruning and maintenance after it is bought and returned home.

Culture methods of Yushu

1. Basin soil requirements: the most suitable time for changing basin soil and planting time is early spring. The basin soil should be loose, fertile and well drained. 2 parts of rotten leaf soil or peat soil, 2 parts of garden soil, 3 parts of coarse sand, 1 part of limestone and gravel, or 3 parts of rotten leaf soil, 3 parts of garden soil, 3 parts of coarse sand, 1 part of bone powder and 1 part of plant ash can be selected as basin soil.

2, temperature requirements: the temperature between 20-30 degrees is most conducive to the growth of Yushu. Spring and autumn are the most suitable growing periods for Yushu. Yushu is afraid of bright lights. When the temperature is high in summer, you should pay attention to keep the plants in the shade to avoid direct sunlight. When the environmental temperature of Yushu is higher than 38 degrees, the growth rate will begin to slow down and even enter a short period of dormancy. In winter, we should pay attention to the temperature, put the plant in the greenhouse, preferably in a place with light. The room temperature should not be lower than 7 degrees. Below 0 degrees will cause the plant to freeze to death. Yushu, which is in its growing period, needs shade except for the high temperature and heat in summer. All should be kept in a sunny place.

3. Watering requirements: when Yushu is in the growing period, the watering frequency should be controlled every two to three days. Can not have the phenomenon of stagnant water should also avoid the basin soil is too wet. Yushu should be cultivated in summer to control the number of watering, and to strengthen ventilation, so as to avoid the phenomenon of fallen leaves. It is necessary to reduce watering when raising Yushu in winter. The specific principles depend on the dry and wet conditions of the basin soil. Micro-drying is better for basin soil.

4. Fertilization requirements: proper fertilization can be applied in the growing period of Yushu. Generally, the rotten thin cake liquid fertilizer is applied 2 or 3 times a month. Adequate base fertilizer should be applied before soil change or planting. Mature organic fertilizer, such as chicken manure, pigeon manure, bone meal, large manure and all kinds of cake fertilizer, can be added to the culture soil as base fertilizer. In order to keep the plant shape plump, the fat and water should not be too large, so as not to cause overgrowth.

Points for attention of Yushu

1. First of all, Yushu grows faster. Every spring, it is necessary to change the basin, add fertile soil, and put it in a sunny place for maintenance.

2. Apply thin fertilizer and water every 10 days and half a month, and water every 2 to 3 days, so that you can see dry and wet. High temperature in midsummer, swallow palm in a semi-dormant state, afraid of strong light burning leaves, at this time to do a good shade maintenance. Summer

3. Stop fertilizing in season and pay attention to ventilation to prevent leaves from yellowing and falling off. If it rains heavily, avoid torrential rain, so as to avoid stagnant water in the roots and death.

From August to October, the autumn turns cool, and the swallow's palm begins to grow again. It is necessary to strengthen the light again and remove the shading equipment. At this time, fertilization and watering are in principle the same as in spring.

5. Frosts Descent went into the greenhouse and put it in the sunny place indoors. Stop fertilizing. Watering should be controlled. Basically, the water should be watered once a month, and the amount of water is 1/2 of that in summer.

How to prune Yushu

1. Pruning in winter is the dormant period of Yushu. At this time, Yushu should be pruned reasonably and properly, so that the Yushu should not be cut short so as not to let the long branches compete for too much nutrients.

2. The flowering period of post-flowering Yushu is in spring and summer. After flowering, the supply of nutrients on the flowering branches is insufficient, so it is necessary to truncate and prune them to grow new branches.

3. Pruning Yushu during the growing period grows relatively fast, so it is necessary to prune the diseased branches of Yushu and the branches that can not achieve the goal. During the growing period, Yushu should be watered less, so as not to control the overall shape. The method of pruning is to top and cut off the tip of the dissatisfied branch so that it does not continue to grow in this direction.

Control methods of diseases and insect pests in Yushu

The main purpose is to prevent and cure anthracnose and leaf spot disease. At the initial stage, 70% methyl topiramate wettable powder is sprayed with 1000 times liquid. When indoor ventilation is poor, stems and leaves are vulnerable to shell insects, which are sprayed with 1000 times omethoate EC when they occur. When watering too much, it is easy to cause root rot, leaves will turn yellow, and even gray mildew spots will rot. Attention should be paid to ventilation and drainage, and carbendazim wettable powder can be sprayed to prevent and cure it if necessary. In addition, there can also be pink scale damage leaves, the formation of white wax powder, should be timely elimination of diseases and insect pests leaves to prevent spread.

The cultivation of Yushu is still very simple, generally from the light, soil and other aspects. Yushu is not tolerant of stagnant water, so drainage should be done in place. The fertilizer should be released when cultivating Yushu. The maintenance in winter is different from that in summer. It should be shaded in summer and sunny in winter.
