There is a big temperature difference in early spring. Flowers and plants should not be moved out too early.

Spring flowers are easy to die

1. If the pot soil is in a dry state for a long time, the flowers and trees will not absorb enough water, and the rapid rise of spring temperature, strong wind and rapid evaporation of water will easily cause imbalance between water supply and demand of flowers and trees, which will eventually lead to their death.

Excessive watering will make the water in the pot soil saturated for a long time, and the root system of the plant will rot or mildew due to lack of oxygen supply, and even lead to death.

3. Excessive fertilization or high concentration of fertilizer are easy to cause root burn, resulting in plant wilt and death. Especially for the newly potted plants, its root absorption capacity is weak, mainly consuming nutrients and water in its own body, at this time fertilization is most likely to burn tender roots.

4. The main pests that cause flowers and trees to wither or even die are scale insects, aphids, scarabs and longicorn beetles. Some of them absorb the liquid in plant tissues, some harm the roots of flowers and trees, and some bite into the xylem of flowers and trees. The main diseases causing flowers and trees death are powdery mildew, blight and so on.

5. The temperature difference between cold and hot in spring is large, and flowers and trees are moved out of the house too early. Flowers and trees are easy to die because they cannot adapt to the rapidly changing weather conditions outside. In addition, the flowers and trees on the pot soon after the new leaves have just grown to get sunlight, will accelerate the evaporation of water on their leaves, resulting in plant water loss death.

Measures to prevent flowers from dying

1. For general flowers and trees, the principle of watering is:

Do not dry do not pour, pour is poured thoroughly.

2. The fertilization principle of potted flowers is that

Thin fertilizer and frequent application

That is, the amount of fertilizer each time should be less but the number of fertilizers should be more.

3, all flowers and trees should not be moved out of the outdoor too early, should wait for the weather conditions to stabilize before moving out. Especially the flowers and trees in the new pot, do not move out of the room too early and put them in the sun, but keep them indoors or in a cool and ventilated place for a period of time, and gradually move them to the sun after they grow stably.

4. To control scale insects and aphids, spray 40% omethoate 1000 times solution or other insecticides; to control chafers, use black light lamp to trap adults, artificially kill adults or use insecticides; to control blight, use 70% thiophanate-methyl WP 1000 times solution to irrigate roots at the early stage of disease.
