Why Flowers and Trees Die Easily in Spring and How to Prevent and Treat It
In spring, flowers and trees should be full of vitality, yet some potted flowers and tree stumps begin to wither and even die after putting out just a few young leaves. The reasons are mainly as follows:
Insufficient water supply:
If the potting soil remains dry for a long time, the flowers and trees cannot absorb enough water. In spring, temperatures rise quickly, the wind is strong, and water evaporates fast, which easily creates an imbalance between water supply and demand in the plants and ultimately leads to their death.
Improper pH:
Plants differ in their biological characteristics; some prefer acidic soil, others prefer alkaline soil. If a plant that prefers acidic soil (such as camellia or azalea) is planted in alkaline soil, it will naturally die, and vice versa.
Pests and diseases:
The main pests that cause the branches and leaves of flowers and trees to wither and even kill the plants include scale insects, aphids, scarab beetles and longhorn beetles. Some of them suck the liquid from plant tissues, some damage the roots, and some bore into the xylem. The main diseases that cause the death of flowers and trees include powdery mildew and damping-off.
The following measures can be taken to prevent flowers and trees from dying in spring:
Water moderately:
For ordinary flowers and trees, the principle of watering is: do not water when the soil is not dry, and water thoroughly when you do.
Fertilize sensibly:
The fertilizing principle for potted flowers is to apply light fertilizer frequently, that is, use a small amount each time but apply it often. To meet the nutrient needs of flowers and trees, if necessary, a 0.5% urea liquid fertilizer or a 0.25% monopotassium phosphate liquid fertilizer can be prepared for foliar feeding. Both excessive fertilization and too high a fertilizer concentration can cause fertilizer burn.
Move them out of the shed in good time:
Do not move any flowers or trees out of the shed too early; wait until the weather is stable before moving them out. In particular, newly potted flowers and trees should not be moved outside into the sunlight too early. Instead, keep them in 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 has stabilized should they gradually be moved into the sunlight.
Prepare the potting soil properly:
When preparing potting soil, consider not only its fertility but also its pH value, to see whether it suits the biological characteristics of the flowers and trees being grown. If the pH value does not meet the requirements, prepare new soil according to the requirements as soon as possible.
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 the adults, handpick the adults, or use insecticides; to control damping-off, drench the roots with a 1000-fold dilution of 70% thiophanate-methyl wettable powder at the early stage of the disease.
Overwatering:
Overwatering keeps the water in the potting soil saturated for a long time, and the plant roots rot or become moldy due to a lack of oxygen, which can even lead to death.
Overfertilization:
Both excessive fertilization and too high a fertilizer concentration easily burn the roots and cause the plant to wither and die. This is especially true for newly repotted plants, whose roots have weak absorption capacity and mainly consume nutrients and water stored in the plant itself; fertilizing at this time is most likely to burn the young roots.
Moving out of the shed too early:
In spring, temperatures alternate between cold and hot with large differences, and moving flowers and trees out of the shed too early makes it easy for them to die because they cannot adapt to the rapidly changing weather outside. In addition, if flowers and trees that were potted not long ago are placed in the sunlight as soon as they grow new leaves, the evaporation of water from the leaf surface speeds up, causing the plant to lose water and die.
