How to deal with three common diseases and insect pests in the maintenance of succulent plants

Flower bonsai network guide: today, the flower bonsai network editor brings you an article on how to deal with the three common diseases and insect pests in the maintenance of succulent plants. Hibiscus snow lotus ranks first, let's take a look.

In the process of raising succulent plants, there are three situations that every succulent player should pay attention to, because each of these situations may cause succulent problems. These three situations are also encountered by every succulent player. I believe you may also encounter, because it is inevitable, but when we encounter, how should we deal with it? You can learn.

1, the situation of bacteria, I believe that many people in the process of raising succulent, more or less encountered the problem of succulent disease. Black rot, black spot and so on. All of this is possible, but do you know what caused it? Yeah, it's because of germs. Very often, when we water too much, or in a dark and humid environment, there will be a large number of bacteria and fungi. Cause pathological changes, the occurrence of succulent plants sick state, do not underestimate the morbidity caused by bacteria, may be irreparable. The solution, not too much watering, try to choose a place with plenty of light, if you encounter such a situation, you should choose to use the medicine at the first time. Completely kill the germs.

Here, I would like to focus on the fact that black rot is caused by fungi, and different plants have different black rot fungi. This kind of fungus can not only infect plants, but also parasitize in the soil. If you want to encounter black rot, you need to change the basin and soil. Plants need to be treated with medicine.

2, the situation of pest disaster, whether it is Xiao Hei Fei or scale insects belong to pest disaster. 100% of succulent players have experienced insect infestation. The impact on succulent plants is also very great. It can even cause succulent death. Some insects also lay eggs in the soil and even spread to other succulent conditions. It is best to choose an environment with plenty of sunshine. The solution is that if you find succulent worms, you need to change the basin and change the soil in time, and the best choice is to treat it with drugs. Completely kill the insects. Here we focus on scale insects, white insects, the size of sesame, with a layer of waxy shell on the surface and strong reproductive ability. It is contagious and has a high incidence period when the temperature and humidity are too high in summer. When you encounter scale insects, you need to change the basin and soil in time, and it is best to isolate a single succulent plant. It needs to be medicated.

3, fertilization, most succulent players choose nutrient soil, but for a long time, nutrient loss, succulent is no longer beautiful, at this time most people feel that there should be no state or environmental problems. In fact, the performance of succulent, may be that there are no nutrients. It is not that there is not enough light and no response to watering. It is caused by the lack of nutrients. There is soil consolidation, impermeable, will also cause succulent not beautiful, not spirit. Here focus on fertilizer, nitrogen fertilizer, can promote the growth of plant branches and leaves, luxuriant branches. The supplement of potash fertilizer can make the plant stem stout, the root system developed, and increase the lodging resistance. However, the best fertilizer choice is slow-release fertilizer, not too much, or it will burn roots.

Speaking of which, you may encounter all three of the above problems. I believe that you who raise succulent plants will think of your succulent diseases, worms and insufficient fertilizer when you see them. Although it is said that everyone can meet, there are still some meat friends who do not know the solution. If you are a novice, worried that encountered these problems can not be solved, and can not bear to watch the lovely succulent die, the editor recommends several super vitality succulent, super easy to raise.

Five management methods of potted flowers in early winter this winter feels particularly early, the leaves on the trees turn yellow slightly, and the wind can't stop blowing, and it's a little unnaturally cold. Although we don't have snow here, I still feel the pace of winter. Early winter is a critical period for nutrition accumulation and flower bud differentiation of potted flowers. however, most potted plants can not stand the cold and frost in winter and are easy to die in winter. the management at this time directly affects the ability of flowers to survive the winter and bloom the following year. The following introduces the winter management methods of potted flowers: 1. Cold prevention: it is necessary to determine the appropriate entry time according to the growth habits of flowers and the demand for temperature. Dormant flowers in winter, such as rose, pomegranate and lotus should be placed indoors from 3 ℃ to 5 ℃; semi-dormant flowers in winter, such as sweet-scented osmanthus, gardenia and camellia, should be placed in a cold greenhouse above 5 ℃; flowers that continue to grow in winter, such as crabapple and carnation, should be placed in a greenhouse of 8 ℃ to 10 ℃ to survive the winter safely. Now many people like to build the courtyard into the style of Southeast Asia, in the plant configuration with tall palm trees with low shrubs, such as palm trees, oleander, Ye Zihua, Fusang, variable leaf trees, pineapples and other Southeast Asian plants are less hardy, winter conservation should be strengthened, should be placed in a place with a suitable temperature to survive the winter. two。 Fertilization: timely fertilization of flowers, basin soil drought should be irrigated in time. In addition, it can be combined with spraying for extra-root topdressing to supplement flower nutrition. The commonly used topdressing is 0.5% urea, 1% calcium superphosphate and 0.3% potassium sulfate. 3. Pruning: rose, Fusang, poinsettia, hibiscus, kumquat, generation flowers and other flowers that bloom on the branches of the current year should be pruned during the winter dormancy period to promote their multiple shoots, flowers and fruits; perennial vines and flowers, cutting off dense branches, overlapping branches and branches of diseases and insect pests; shrubs with ornamental branches, such as red rosewood, choose the new shoots close to the backbone branches to make them produce new branches. 4. Loose soil: poor ventilation will hinder respiration, affect the normal growth and even death of flowers. The soil should be loosened in time to keep the basin soil loose. 5. Diseases and insect pests: in early winter, when the temperature decreases, the activities of diseases and insect pests decrease, but they should also be prevented and controlled in time. Although the winter is relatively cold, it is not the time for mosquitoes to lay eggs and breed, but there will still be insects parasitic on plants to spend the winter, so it is necessary to strengthen management. Emphasis should be placed on the prevention and control of diseases and insect pests such as leaf perforation, aphids, red spiders and leaf moths. Generally, we can choose 50% carbendazim 800 times solution plus 40% dimethoate EC 1500 times liquid, or 50% carbendazim wettable powder 600 times liquid plus 40% isocarbophos 1000 times solution and other medicament control. In order to make the garden potted flowers safely through this cold winter, we should take good care of our own flowers as well as ourselves. As long as we do the above, the flowers in the courtyard will bloom more brightly in the coming spring.
