It doesn't matter if the flowers are practical. Here are the most comprehensive remedial measures

In the process of growth and development of potted flowers, due to the environmental factors and the reasons of flowers themselves, the growth of potted flowers is inhibited, and in serious cases, flowers will die. Therefore, measures must be taken to maintain and rejuvenate them in time.

1. Because of the long-term drought, the flowers and trees were not watered in time, and began to wilt from the top, and the cortex of branches and trunks shrunk until the whole plant died. In this case, it is necessary to spray water on the leaves of dry flowers and trees and the surrounding environment to keep a high humidity. It is forbidden to use a large amount of water with low temperature to irrigate the soil in high temperature environment.

2. If the water content in soil is too high, the plant roots will be suffocated or suffocated, and the branches and leaves will be withered or even withered if they can not get the water supply from the roots. The injured flowers and trees should be avoided direct sunlight and strong wind, and part of tender branches and leaves should be cut off to reduce water evaporation. The flowers and trees planted in the ground should be loosened in time. For potted plants, remove one third of the over wet pot soil, replant the dry soil, spray thin liquid fertilizer every three days in combination with spraying water on the leaf surface. After 10 days of maintenance, the injured flowers and trees can recover.

3. The high concentration of fertilizer in the soil of flowers and trees makes the water in flowers and trees penetrate into the soil (i.e. reverse osmosis), commonly known as burning roots, causing the flowers and trees to wither or even die. The damaged flowers and trees planted in the soil can be irrigated with large amount of water to dilute the fertilizer concentration in the soil and discharge it in time. Potted flowers and trees, remove the surface soil, water irrigation, so that excessive fertilizer with water from the lower part of the pot, and then in the basin covered with a layer of plain soil. At the same time, the injured flowers and trees were shaded and sprayed with water to maintain the life of the branches and leaves of the flowers and trees. After 10 to 20 days, they could return to normal.

4. When the damage is serious, longicorn beetles and gymnodinids damage the main stem or main branch of flowers and trees, causing local or whole plant wilting or dying. The wilting caused by insect pests is difficult to recover. The branches of precious flowers and trees can be cut off for cutting or grafting.

5. When the new shoots, especially the spring shoots, grow in large numbers, they often wilt when they encounter strong light and strong wind (especially dry wind). At this time to take shade, shelter from the wind, spray water on the leaf surface can prevent the new shoots from wilting due to water loss.

6. Hot summer like cool environment of flowers, if placed in a strong light, high temperature place, the leaves will appear wilting and involution, even withered yellow off. It should be placed in a moist, ventilated and cool place immediately.

7. In the north of Lengyan, the temperature fluctuates greatly, and the night temperature suddenly drops below 10 ℃. Some southern flowers, such as hibiscus, jasmine and rhododendron, will wither and lose luster in the morning, and gradually recover after the temperature rises at noon. Short time cold wilting has little effect on flowers, but we should pay attention to keep warm.
