Causes and treatment methods of Flower withering in Spring

Spring is the season when everything recovers. Many flowers will blossom in this season, but they will die soon. What is the cause of this? How should we deal with it?

First, too much watering: too much watering will make the water in the basin soil saturated for a long time, the root system of the plant will rot or mildew or even lead to death due to lack of oxygen supply.

Second, excessive fertilization: excessive fertilization or too high concentration of fertilizer can easily cause root burning to cause plant wilt and death. In particular, the weak root absorption capacity of the newly changed plants is mainly due to their own nutrients and water. At this time, fertilization is the most easy to burn the tender roots.

Third, leave the shed too early: the temperature difference between cold and hot in spring is too early to move the flowers and trees out of the shed because they are unable to adapt to the rapidly changing external weather conditions, which is easy to cause death. In addition, as soon as the flowers and trees in the pot grow new leaves, exposure to the sun will accelerate the evaporation of water on the leaves, resulting in the loss of water and death of the plants.

Fourth, insufficient water supply: if the potted soil is in a state of drought for a long time, the flowers and trees will not absorb enough water, while the spring temperature rises fast, the wind is strong, and the water evaporates quickly, it is easy to cause the imbalance between water supply and demand of flowers and trees, and eventually lead to their death.

5. Improper acidity and alkalinity: plants have different biological characteristics, some like acid soil and some like alkaline soil. Plants that like acidic soil (such as camellias, rhododendrons) will die naturally if they are planted in alkaline soil.

Diseases and insect pests: the main pests that cause the withering of branches and leaves of flowers and trees and even the death of plants are shell insects, aphids, beetles, longicorn beetles and longicorn beetles, some of which absorb liquid from plant tissues, some harm the roots of flowers and trees, and some decay into the xylem of flowers and trees. The main diseases causing the death of flowers and trees are powdery mildew, blight and so on.

Ways to prevent flowers from withering in spring

China Garden Network, Feb. 28: flowers and trees in spring should be full of vigor and vitality, but some potted flowers and stumps begin to wither or even die after sending out a few tender leaves. The main reasons are as follows:

Too much watering

Too much watering will make the water in the basin soil saturated for a long time, and the root system of the plant will rot or mildew or even lead to death due to lack of oxygen supply. Excessive fertilization: excessive fertilization or too high concentration of fertilizer can easily cause root burning to cause plant wilt and death. In particular, the weak root absorption capacity of the newly changed plants is mainly due to their own nutrients and water. At this time, fertilization is the most easy to burn the tender roots. Leave the shed too early: the temperature difference between cold and hot in spring is too early to move the flowers and trees out of the shed because they are unable to adapt to the rapidly changing external weather conditions, which is easy to cause death. In addition, as soon as the flowers and trees in the pot grow new leaves, exposure to the sun will accelerate the evaporation of water on the leaves, resulting in the loss of water and death of the plants. Insufficient water supply: if the potted soil is in a state of drought for a long time, the flowers and trees will not absorb enough water, while the spring temperature rises fast, the wind is strong, and the water evaporates quickly, it is easy to cause the imbalance between water supply and demand of flowers and trees, and eventually lead to their death.

The main diseases causing the death of flowers and trees are powdery mildew, blight and so on.

The following measures can be taken to prevent flowers and trees from withering in spring:

Appropriate watering: for general flowers and trees, the principle of watering is not dry or watered thoroughly. Rational fertilization: the fertilization principle of potted flowers is to apply thin fertilizer frequently, that is, the amount of fertilizer each time should be less, but the times of fertilization should be more. In order to meet the nutrient needs of flowers and trees, 0.5% urea liquid fertilizer or 0.25% potassium dihydrogen phosphate liquid fertilizer can be prepared for foliar fertilization if necessary. Excessive fertilization or too high concentration of fertilizer will cause fertilizer damage. Get out of the shed in time: all flowers and trees should not be moved out of the shed too early until the weather is stable. In particular, the flowers and trees in the new pot should not be moved out of the shed and exposed to the sun prematurely, but should be maintained in the shed or in a cool and ventilated place for a period of time (usually out of the shed after mid-April) before they can be gradually moved to the sun after their growth is stable. Proper preparation of basin soil: in the process of basin soil preparation, we should consider not only its fertility but also its pH value to see whether it accords with the biological characteristics of the flowers and trees. If the pH value does not meet the requirements, the new soil should be prepared as soon as possible. Effective control of diseases and insect pests: control of shell insects and aphids with 1000 times of omethoate or other insecticides; control of beetles with black light trapping adults, manual killing of adults or insecticides; control of blight disease can be irrigated with 1000 times of methyl topiramate wettable powder at the initial stage of the disease.
