Spring flowers and trees should be full of vigor and vitality, but some plants and stumps will begin to wither and even die after sending a few leaves. The reasons are mainly the following:
Excessive watering: Excessive watering will cause long-term saturation of the water in the basin soil, and the plant's root system will rot or mold due to lack of oxygen supply, and even cause death.
Excessive fertilization: Excessive fertilization or excessive fertilization can easily cause burning of roots, leading to death of plants. Especially for the newly-changed plants, its root absorption capacity is weak, and the main consumption is from the nutrients and moisture in the body. At this time, fertilization is the most likely to burn out the tender roots.
Shedging is too early: Spring is hot and cold, and there is a large temperature difference, and the flowers and trees are moved out of the shed prematurely. Flowers and trees can easily cause death because they cannot adapt to the rapidly changing weather conditions. In addition, the soon-to-be-flowered plants in the upper basin just took out new leaves and received sunlight, which would accelerate the evaporation of their leaves, causing the plants to lose water, leading to death.
Insufficient water supply: If pots are in a state of drought for a long time, flowers and trees will not be able to absorb enough water. In spring, the temperature rises quickly, the wind is large, and the water evaporates quickly. It is easy to cause unbalanced supply and demand of flowers and trees, and eventually cause death.
Inappropriate pH: The biological characteristics of the plants vary, some prefer acidic soils and some have alkaline soils. If plants in acidic soils (such as camellia and rhododendron) are planted in alkaline soils, the plants cannot survive and naturally die, and back there.
Diseases and Insect Pests: The main pests that cause the flowers and branches to wither and even die are the scale insects, aphids, beetles, and long-horned cows. Some of them absorb fluids from plant tissue, some of them harm the roots of flowers and some fall into the xylem of flowers and trees. Diseases that cause death of flowers and trees include powdery mildew and blight.
