Potted flowers in the growth and development process, due to environmental factors and the reasons for the emergence of flowers itself wilting phenomenon, so that the growth of flowers is inhibited, in severe cases, the flowers will die, must take measures to timely maintenance and rejuvenation. I. Drought and flood: Long-term drought of flower trees failed to water in a timely manner, from the top began to wilt down, branch cortex collapsed until the whole plant died. Under such circumstances, it is necessary to spray water on the leaves and surrounding environment of drought flowers and trees to maintain a high environmental humidity, and avoid using large amounts of low-temperature water to irrigate soil under high temperature. Second, blisters: water in the soil is too large, the plant roots breathing is blocked or suffocated and died, the branches and leaves do not get root water supply, is bound to wilt or even die. The victims should avoid direct light and strong winds blowing directly from the damaged flowers and trees, cut off some tender shoots, and reduce the evaporation of water. To plant the flowers and trees in time to loosen the soil. Potted flowers and trees, removed one-third of the wet soil, plus dry soil replanted, combined with foliar spray, spray a thin liquid fertilizer every three days, so conservation for 10 days, the affected flowers and trees can be recovered. 3. Fertilizer: The excessive concentration of fertilizers in the flowers and trees causes the moisture in flowers and trees to penetrate into the soil (that is, reverse osmosis). This is commonly known as burning roots, causing wilting and even death of flowers and trees. To plant the damaged flowers and trees, it can be diluted with water to dilute the concentration of fertilizer in the soil and discharged in time. Potted flowers and trees, remove the topsoil in pots, water irrigation, so that too much fertilizer with water from the lower part of the flower pots, and then cover the surface of a layer of prime soil. At the same time, measures such as shading and spraying water on the affected flowers and trees were adopted to maintain the life of flowers and leaves. After 10 days to 20 days, the disease could return to normal. 4. Insect mites: When the calf and the gibberella are seriously damaged, the transmitting tissue of the trunk or main branch of the flowers and trees is damaged, causing partial or whole wilting or dead, and the wilting caused by insect pests is difficult to recover. The precious flowers and trees can be used for twigs. Cut, cut or graft. V. Wind blowing: New shoots of flowers and trees, especially when spring shoots grow in large numbers, encounter strong light and strong wind (especially dry wind), and flowers and trees often wilts. At this time, shading, sheltering, and spraying water on the leaves will prevent the shoots from losing water and wilting. Sixth, enthusiasm: summer flowers like a cool environment, if placed in a strong light, high temperature, the leaves will appear wilting roll, and even yellow off. Immediately put it in a moist, ventilated, cool place. 7. Cold borealis: The temperature in the north fluctuates greatly, and the nighttime temperature suddenly drops below 10°C. Some southern flowers such as hibiscus, jasmine and rhododendrons are wilted and lose their luster in the morning, and gradually recover after noon temperatures rise. Short-term cold chilling has little effect on flowers, but it should be kept warm.
