Crassula Arborescens, is known as Sedum pachyphyllum. It is a succulent shrub of the genus Cyclosaurus of the Crassulaceae family. It is native to tropical Africa and is evergreen all the year round.A flower friend recently asked, "Some leaves of my Crassula Arborescens seem to have dried out in recent days. Are they sunburnt?" What should we do if it gets sunburnt? Is there a good way to deal with it? The following flower information introduces the causes of Crassula Arborescens sunburn and the treatment methods of Crassula Arborescens sunburn, which is only for the reference.   Generally, there are several situations that cause the leaves of Crassula Arborescens to dry, but it is not entirely due to sun exposure. It may be caused by lack of ventilation, too much watering and too much fertilizer.   Treatment of Crassula Arborescens sunburn   1. The suitable temperature for the growth of Crassula Arborescens is 20-30 ℃. Spring and autumn are suitable for growth periods. Shade or place under the shade of trees when it is hot in summer to avoid direct sunlight. When the temperature exceeds 38 ℃, it grows slowly or enters into temporary dormancy.   In winter, it should be put in the greenhouse or in a sunny place indoors. The room temperature should be kept at 7-10 ℃, and the temperature should not be lower than 5 ℃. If it is below 0 ℃, it will be frozen to death. During the growth period, except for the need for shade in hot summer, it should be placed in a sunny place.   2. During the growth period of Crassula Arborescens, water once every 2-3 days, but do not make the soil too wet, let alone water. When it is hot in summer, watering shall be strictly controlled and ventilation shall be strengthened, otherwise it is easy to cause fallen leaves. In winter, water should be reduced, and the pot soil should be slightly dry. Watering gradually decreases in autumn. During outdoor cultivation, it is necessary to avoid rain washing, otherwise excessive water in the root will easily cause root rotting and death.   [Tips] When Crassula Arborescens gets sunburnt, it should first be kept in a light scattering place for a period of time, and then directly bask in the sun. Crassula Arborescens likes loose sandy culture soil, and avoids too wet soil. If the pot soil is too wet, and the ventilation is poor, it is easy to lose leaves. When it is hot in midsummer, Crassula Arborescens is in a semi dormant state. It is OK not to water it for many days. Besides, fertilization should be stopped, and ventilation should be paid attention to to prevent the leaves from becoming sunburnt.

       In summer, although the temperature is relatively high, people still live a lively and active life in such a high temperature, and summer is also a season suitable for planting flowers in plastic flower pots. 　　Because of the temperature, people are always used to planting a lot of flowers in summer, watching those bright fireworks bloom and feeling the strong breath of life this summer. When planting flowers in summer, especially at home, most people choose plastic flower pots. On the one hand, it is because the plastic flower pot is lighter in material and more convenient to carry; on the other hand, because the plastic flower pot is low in cost, buying in large quantities will not bring economic burden, and it is more worthy of people's choice.

　　Modern people pursue a healthy lifestyle, and qualified families choose to use the balcony space to grow green vegetables by themselves. Just because the balcony conditions are limited, people mostly choose plastic flowerpots to plant, will the vegetables grown in this way be poisonous? 　　The reason why people raise such questions is because many plastic products can cause harm to the human body, which makes people have to have related questions about plastic flower pots. To answer this question, let's first take a look at what substances are absorbed in the growth of vegetables. Vegetable roots mainly absorb water and inorganic salts in production, and vegetable roots also absorb amino acids, sodium phytate, nucleotides and other substances, but cannot absorb macromolecules.        The main component of plastic flower pots is synthetic resin, which has stable chemical properties and cannot be explained, and a small amount of organic matter decomposed cannot be absorbed by vegetable roots. When plastic is burned, dioxin is produced. Although it is carcinogenic to the human body, it cannot be absorbed by vegetable roots. Therefore, vegetables grown in plastic flower pots are not poisonous. However, we cannot use plastic flowerpots to grow vegetables without restrictions, because most of the flowerpots on the market are made of waste plastics, and there will still be harmful substances left. You'd better choose a flowerpot with no odor to grow vegetables.

　　When it comes to plastic flower pots, many of my friends' impressions are on novel and beautiful shapes and colorful colors, but I don't know if you have paid attention to the production materials of plastic flower pots? The manufacturer will give you a brief introduction next. 　　The white plastic flower pots we usually see are made of PVC, PP and PE. However, there are many colors of plastic flower pots. What materials are those blue, yellow, red, and pink plastic flower pots made of? First of all, ABS plastic, which is the most commonly used material for straight flower pots. The advantage is that the price is lower than that of the PA flowerpot, but it is relatively brittle and has poor impact strength, and is mostly used as a telephone casing and a TV casing. 　　Nylon can also be used to make flower pots because of its strength and moisture absorption, but its price is nearly double that of ABS. In addition, high-pressure polypropylene material can also be used to make plastic flower pots, which have low toxicity, good high temperature and low temperature resistance, and low cost.

　　Friends who like to plant all kinds of flowers are no strangers to plastic flower pots. Whether it is growing flowers at home or green plants in the office, we all think that plastic flower pots and trays are more suitable. 　　The planting of flowers is inseparable from water, air and sunlight. Both air and sunlight can directly contact flowers without leaving any traces, but water cannot. People are accustomed to choosing plastic flower pots to grow flowers, but when they forget to water the flowers, the excess water will penetrate the outside of the flower pot through the soil, leaving traces on the windowsill and table, affecting the growth of flowers and causing indoor environment. worse. 　　Manufacturers engaged in flower pot production also sell trays, and trays of various specifications and sizes correspond to different types of plastic flower pots. Put trays under the pots, and the excess water will not stain the windowsills and tables when watering the flowers, which is both beautiful and practical. Our factory has prepared flower pots and trays of various colors and shapes for you who love flowers. Friends in need can come to our factory and the official website to buy as much as you like.
