Prevention methods of withering and dying of flowers and trees in spring

After a cold winter, flowers and trees will enter the vigorous growth of spring, but many flower friends have found that flowers and trees are easy to die in spring when everything recovers. What is the reason for this? How to prevent flowers and trees from dying in spring?

1. Appropriate watering: for general flowers and trees, the principle of watering is that if you don't dry or water, you will water thoroughly.

2. Rational fertilization: the fertilization principle of potted flowers is that the amount of fertilizer applied each time should be less, but the times of fertilization should be more. 0.5% urea liquid fertilizer or 0% can be prepared if necessary to meet the nutrient needs of flowers and trees. 25% of potassium dihydrogen phosphate liquid fertilizer was used for foliar fertilization. Excessive fertilization or too high concentration of fertilizer will cause fertilizer damage.

3. Get out of the shed in time: all flowers and trees should not be moved out of the shed prematurely 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.

4. Proper preparation of basin soil: in the process of basin soil preparation, not only its fertility but also its pH value should be considered to see whether it accords with the biological characteristics of the flowers and trees planted. If the pH value does not meet the requirements, the new soil should be prepared as soon as possible.

5. Effective prevention and control of diseases and insect pests: control of shellfish 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.

What if the flowers and trees die in spring? Prevention and control methods of flowers and trees dying easily in spring

What if the flowers and trees die in spring? Spring flowers and trees are easy to die control methods-spring flowers and trees 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:

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.

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 flower and tree branches and leaves to wither and even plant death 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.

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.

Too much watering: too much watering will make the water in the basin soil saturated for a long time. The roots of the plant rot or mildew or even die 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.
