What to Do When Flowers Die in Spring? Cause Analysis and Treatment Methods

Spring is the season when all things revive, and many flowers bloom in this season, but they soon die off. What exactly causes this? And how should it be handled?

1. Overwatering:Overwatering keeps the moisture in the potting soil in a saturated state for a long time, and the plant's root system rots or becomes moldy due to lack of oxygen supply, and may even die.

2. Overfertilizing:Overfertilizing or applying fertilizer at too high a concentration can easily burn the roots and cause the plant to wither and die. This is especially true for newly repotted plants, whose root systems have weak absorption capacity and mainly consume their own internal nutrients and water; fertilizing at this time is most likely to burn the young roots.

3. Moving out of the shed too early:In spring, temperatures fluctuate between cold and warm with large differences, and moving flowers and trees out of the shed too early makes them prone to death because they cannot adapt to the rapidly changing external weather conditions. In addition, for flowers and trees that have just been potted, taking them into sunlight as soon as they grow new leaves will accelerate water evaporation from the leaf surface, causing the plant to lose water and die.

4. Insufficient water supply:If the potting soil remains dry for a long time, flowers and trees cannot absorb enough water. In spring, temperatures rise quickly, winds are strong, and water evaporates quickly, which easily creates an imbalance between water supply and demand in flowers and trees, ultimately leading to their death.

5. Improper pH:Plants have different biological characteristics; some prefer acidic soil, while others prefer alkaline soil. If plants that prefer acidic soil (such as camellia and rhododendron) are planted in alkaline soil, they will naturally die, and vice versa.

6. Pests and diseases:The main insect pests that cause flowers and trees to wither and even die include scale insects, aphids, scarab beetles, and longhorn beetles. Some suck fluids from plant tissues, some damage 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, damping-off, and so on.

How to Prevent Flowers from Dying in Spring

News from the China Landscape Web on February 28: In spring, flowers and trees should be full of vitality and vigor, 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:

Overwatering

To prevent flowers and trees from dying in spring, the following measures can be taken:

Water appropriately: For ordinary flowers and trees, the principle of watering is not to water when dry, and to water thoroughly when watering. Fertilize reasonably: The fertilization principle for potted flowers is to apply thin fertilizer frequently, that is, apply a small amount each time but fertilize more often. To meet the nutrient needs of flowers and trees, if necessary, a 0.5% urea liquid fertilizer or 0.25% potassium dihydrogen phosphate liquid fertilizer can be prepared for foliar feeding. Overfertilizing or applying fertilizer at too high a concentration can both cause fertilizer damage. 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 the 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 of the shed until after mid-April), and only after their growth is stable can they be gradually moved into sunlight. Prepare potting soil appropriately: When preparing potting soil, both its fertility status and especially its pH value should be considered to see whether it suits the biological characteristics of the flowers and trees being planted. If the pH value does not meet the requirements, new soil should be prepared 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 blacklight traps to kill adults, manually capture 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.
