Methods for preventing and treating the withering disease of flowers and plants
This article introduces you to the relevant knowledge of flower clinics, including the prevention and treatment methods for the withering disease of flowers and plants. The following editor will provide you with detailed answers.
During the growth and development of flowers, withering phenomena may occur due to environmental factors and inherent reasons of the flowers, which inhibit the growth of the flowers. In severe cases, it can lead to the death of the flowers, and timely measures must be taken for maintenance and rejuvenation.
Here are several situations of withering in flowers and plants:
One, drought withering: When trees and shrubs are drought-stressed and not watered in time, they start to wither from the top down, with the bark of the stems shriveling until the entire plant dies. In this case, spray water on the leaves and surrounding environment of the drought-stressed trees and shrubs to maintain a higher environmental humidity. Avoid using a large amount of cold water to irrigate the soil in a high-temperature environment.
Two, water withering: When the soil contains too much water, the plant roots are unable to breathe or suffocate and die, causing the branches and leaves to be deprived of water from the roots and inevitably wither or even die. For affected trees and shrubs, avoid direct sunlight and strong winds, cut off some of the tender branches and leaves to reduce water evaporation. For ground-planted trees, loosen the soil in time. For potted trees, remove one-third of the overly wet potting soil, add dry soil, and replant, combined with foliar spraying. Spray a dilute liquid fertilizer every three days. With such care for 10 days, the affected trees can recover.
Three, fertilizer withering: When the concentration of fertilizer in the soil of trees and shrubs is too high, the water in the plants渗透 into the soil (i.e., reverse osmosis), commonly known as root burn, causing the plants to wither or even die. For ground-planted trees, flood the soil to dilute the fertilizer concentration and drain it in time. For potted trees, remove the topsoil in the pot, water it, and allow the excess fertilizer to flow out from the bottom of the pot. Then cover the surface with a layer of plain soil. Also, take measures such as shading, foliar spraying to maintain the life of the branches and leaves of the affected trees. After 10 to 20 days, they can return to normal.
Four, insect withering: When serious damage is caused by pests like longicorn beetles or flatheaded borers, which destroy the conductive tissues of the main stem or branches, it can lead to local or whole-plant withering or death. Withering caused by pests is difficult to recover. For valuable trees, cut the branches and propagate them through cutting or grafting.
Five, wind withering: When new shoots, especially spring shoots, grow rapidly and encounter strong sunlight and strong winds (especially dry winds), trees and shrubs often wither. In this case, take measures such as shading, wind protection, and foliar spraying to prevent the new shoots from losing water and withering.
Six, heat withering: In summer, flowers that prefer cool environments, if placed in areas with strong sunlight and high temperatures, may experience withered and curled leaves, and even yellowing and falling off. They should be immediately moved to a moist, ventilated, and cool place.
Seven, cold withering: In the north, where temperature fluctuations are large, if the nighttime temperature suddenly drops below 10°C, leaves of some southern flowers such as hibiscus, jasmine, and azaleas may wither and lose their luster in the morning and gradually recover as the temperature rises at noon. Short-term cold withering has little effect on flowers, but attention should be paid to keeping them warm.
The above introduces the complete prevention and treatment methods for the withering disease of flowers and plants for everyone to learn and understand!
