How to prevent flowers and trees from dying in spring? Sharing practical methods
After a cold winter, flowers and trees enter the vigorous growing season of spring, but many gardening enthusiasts find that, in spring when all things revive, flowers and trees are instead prone to dying. What exactly causes this? And how should spring dieback of flowers and trees be prevented?

1. Water moderately: For ordinary flowers and trees, the principle of watering is no watering when dry, and water thoroughly when you do water.
2. Fertilize reasonably: The fertilizing principle for potted flowers is light fertilizer applied frequently, that is, the amount of fertilizer each time should be small but the number of applications should be greater. To meet the nutrient needs of flowers and trees, when necessary, a 0.5% urea liquid fertilizer or 0.25% monopotassium phosphate liquid fertilizer can be prepared for foliar feeding. Excessive fertilization or too high a fertilizer concentration will both cause fertilizer damage.
3. Move out of the shed in time: All flowers and trees should not be moved out of the shed too early; they should be moved out only after weather conditions are stable. In particular, newly potted flowers and trees should not be moved out of the shed too early and placed in sunlight; instead, they should be kept inside the shed or in a cool, ventilated place for a period of care (generally not moved out until after mid-April), and only after their growth is stable can they be gradually moved into sunlight.
4. Prepare the potting soil appropriately: In the process of preparing potting soil, both its fertility status and, even more, its pH value should be considered, to see whether it matches the biological characteristics of the flowers and trees being grown. If the pH value does not meet the requirements, new soil should be prepared according to the requirements as soon as possible.
5. Effectively prevent and control pests and diseases: To control scale insects and aphids, spray with a 1000-fold dilution of 40% omethoate or other insecticides; to control scarab beetles, use black light traps to kill adults, manually capture adults, or use insecticides; to control damping-off disease, drench the roots with a 1000-fold dilution of 70% thiophanate-methyl wettable powder in the early stage of the disease.
What to do about spring dieback of flowers and trees? Control methods for flowers and trees that are prone to dying in spring
What to do about spring dieback of flowers and trees? Control methods for flowers and trees that are prone to dying in spring--In spring, flowers and trees should be full of vigor and vitality, but some potted flowers and tree stumps begin to wither and even die after producing a few tender leaves. The main reasons are as follows:
Insufficient water supply:
If the potting soil remains dry for a long time, flowers and trees cannot absorb enough water; and in spring, temperatures rise quickly, winds are strong, and water evaporates quickly, which easily causes an imbalance between water supply and demand in flowers and trees, ultimately leading to their death.
Improper pH:
Plants differ in their biological characteristics; some prefer acidic soil, while others prefer alkaline soil. If a plant that prefers acidic soil (such as camellia and azalea) is planted in alkaline soil, the plant will naturally die, and vice versa.
Pests and diseases:
The main pests that cause flowers and trees to wither in branches and leaves and even cause plant death include scale insects, aphids, scarab beetles, and longhorn beetles; some suck liquids within plant tissues, some harm the roots of flowers and trees, and some bore into the xylem of flowers and trees. The main diseases that cause the death of flowers and trees include powdery mildew and damping-off disease.
The following measures can be taken to prevent spring dieback of flowers and trees:
Water moderately:
For ordinary flowers and trees, the principle of watering is no watering when dry, and water thoroughly when you do water.
Fertilize reasonably:
The fertilizing principle for potted flowers is light fertilizer applied frequently, that is, the amount of fertilizer each time should be small but the number of applications should be greater.

Overwatering:
Overwatering will keep the water in the potting soil in a saturated state for a long time, and the plant's root system will rot or become moldy due to lack of oxygen supply, and may even lead to death.
Excessive fertilization:
Excessive fertilization or too high a fertilizer concentration can easily burn the roots and cause the plant to wither and die. In particular, for newly repotted plants, their root absorption capacity is weak and they mainly consume nutrients and water from within themselves; fertilizing at this time is most likely to burn the tender roots.
Moving out of the shed too early:
In spring, temperatures fluctuate between cold and hot, and the temperature difference is large. If flowers and trees are moved out of the shed too early, they may easily die because they cannot adapt to the rapidly changing weather conditions outside. In addition, if flowers and trees that have been potted for only a short time are taken into sunlight as soon as they grow new leaves, this will accelerate water evaporation from the leaf surface and cause the plant to lose water and die.
