Disease control is mainly based on prevention. First of all, the environment should be clean. Exotic plants must be strictly controlled, and only when there are no diseases and insect pests can they be placed in sheds or balconies and other planting spaces. Early winter, early spring, plum rain before these three periods to the succulent plants concentrated spraying has twice the result with half the effort. In addition, it has a good preventive effect on the disinfection of culture soil.

Mealybugs like to feed on the youngest parts of plants, so you'll always find them near growing points and shoots. Occasionally found on the stem, because they are coming out of the soil, but also in the turtle speed to climb up, really slower than snails. There were indeed some insects that were too lazy to crawl. They did not have any high aspirations and just lay in the soil to suck the sap from the roots of plants.

Generally, if you open the soil and find white powder or white floc, it is secreted by mealybugs, and translucent larvae or eggs can be found inside. The eggs are very small in diameter and can be viewed under a magnifying glass. There is also a point that cannot be taken lightly, many adults often lie on the back of the leaf and petiole angle and other parts that are not easy to be detected, inspection of the ground part can not only check the growth point. Affected plants will weaken, slow down or stop growing, lose water and dry up. It can also cause flower buds and leaves to fall off. In severe cases, the plants die in pieces.

Many flower friends often ignore this point, or do not take it seriously, that is, the high temperature disinfection of flowers and soil, this is definitely the best defense. The flower soil bought from the flower market, no matter how the boss boasted how clean and sanitary the flower soil was imported, you had to buy it and disinfect it at high temperature. This was to lay a solid foundation.

The first function of high temperature is to destroy bacteria, and the second most important function is to destroy eggs. In fact, the elimination of bacteria is only temporary elimination, because in the later stage as long as the temperature and humidity are right, there will still be a large number of bacteria in the flowerpot, because bacteria are all-pervasive. But the elimination of the eggs is strategic! It is not excluded that eggs that are difficult to find with the naked eye are accidentally spread on objects such as flower organs or spread with the wind, but that is already insignificant compared to the number of eggs in the flower soil.

Autumn succulent plants watering can press "in the growth period of varieties more watering, less watering dormant varieties;" Healthy plants growing vigorously more watering, growing weak plants less watering "principle, in August to September in many areas of our country there will be hail, heavy rain, typhoon, strong storms and other bad weather, late autumn in the north will also appear frost, cold, these will cause great damage to succulent plants, serious or even" annihilated ", so that the cultivation of many years of plants destroyed. Therefore, be extra careful, pay attention to meteorological information frequently, and do a good job of prevention to prevent damage to plants caused by bad weather.
