Reasons and Remedial Measures for Withering of Flowers and Trees
Let's talk about the planting content of the flower clinic, the reasons for the withering of flowers and trees and the remedial measures, follow the editor to take a look!
During the growth and development of potted flowers, withering phenomena occur due to environmental factors and the 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 revitalization.
One, Drought Withering: When flowers and trees are not watered in time after long-term drought, they start to wither from the top down, the stem cortex shrinks until the whole plant dies. In this situation, spray water on the leaves of the drought-stricken flowers and the surrounding environment, maintain a higher humidity, and 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's root system is obstructed from breathing or suffocates to death, and the branches and leaves do not receive water from the roots (G-Y), which will inevitably lead to withering or even death. For the affected flowers and trees, avoid direct sunlight and strong wind, cut off some tender branches and leaves to reduce water evaporation. For flowers planted in the ground, loosen the soil in time. For potted flowers, remove one-third of the overly wet soil and replace it with dry soil, and then spray water on the leaves, followed by a thin liquid fertilizer every three days. With such maintenance for 10 days, the affected flowers and trees can recover.
Three, Fertilizer Withering: When the fertilizer concentration in the soil of the flowers and trees is too high, the moisture in the flowers and trees渗透ates into the soil (i.e., reverse osmosis), commonly known as root burn, causing withering or even death. For the affected flowers and trees planted in the ground, pour a large amount of water to dilute the fertilizer concentration in the soil and drain it in time. For potted flowers, remove the topsoil in the pot, water it, and let the excess fertilizer flow out from the bottom of the pot, then add a layer of plain soil on the surface. At the same time, take measures such as shading, spraying water on the leaves to maintain the life of the branches and leaves. After 10 to 20 days, it can return to normal.
Four, Insect Withering: When the damage caused by longicorns or flat-headed borers is severe, it destroys the conducting tissue of the main stem or branches of the flowers and trees, causing local or whole plant withering or death. Withering caused by pests is difficult to recover, and for valuable flowers and trees, the branches can be cut and used for cutting or grafting.
Five, Wind Withering: When the new shoots of flowers and trees, especially the spring shoots, grow rapidly and encounter strong sunlight and strong wind (especially dry wind), withering often occurs. In this case, taking measures such as shading, avoiding wind, and spraying water on the leaves can prevent the new shoots from withering due to water loss.
Six, Heat Withering: If cool-season flowers are placed in a high light and high-temperature environment in summer, the leaves will appear to wither, curl inward, and even turn yellow and fall off. They should be immediately moved to a humid, well-ventilated, and cool place.
Seven, Cold Withering: In the north, where there is a large fluctuation in temperature, if the night temperature suddenly drops below 10°C, leaves of some southern flowers such as hibiscus, jasmine, and azaleas will 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 warm.
