With the improvement of living standards, more and more families have started to care for potted plants, among which chrysanthemums are deeply loved for their colorful blooms and long flowering period. During the maintenance process, many flower enthusiasts may find that the flowers of potted chrysanthemums show signs of internal rot, which not only affects the ornamental value of the chrysanthemums but may also threaten the health of the entire plant. This article will provide a detailed analysis of the reasons for the internal rot of potted chrysanthemum flowers and the methods to prevent and treat it, helping enthusiasts to better care for their beloved chrysanthemums.
Reasons for the Internal Rot of Potted Chrysanthemum Flowers1. Improper Water Management
Chrysanthemums enjoy sunlight and are drought-resistant but do not tolerate waterlogging. If overwatered, the soil may become too moist, leading to root hypoxia and subsequent root rot, which then affects the internal health of the flowers.
2. Improper Fertilization
Excessive fertilization or the use of insufficiently decomposed organic fertilizers can lead to high soil salinity, affecting the roots' absorption of water and nutrients, resulting in root rot and thus impacting the flowers.
3. Disease and Pest Infection
Chrysanthemums are susceptible to diseases and pests during growth, such as powdery mildew and black spot diseases. If these diseases are not treated promptly, they can lead to internal rot of the flowers.
4. Environmental Factors
High temperature, high humidity, and poor ventilation can easily cause rot in the leaves and flowers of chrysanthemums.
Methods to Prevent and Treat Internal Rot of Potted Chrysanthemum Flowers1. Water Management
Reasonable watering is the key to preventing internal rot in chrysanthemum flowers. Generally, keeping the soil slightly moist is sufficient, avoiding excessive watering. During the hot summer season, the frequency of watering can be appropriately reduced.
2. Fertilization Management
Fertilization should be moderate and avoid excess. Organic fertilizers should be fully decomposed to reduce soil salinity. After fertilizing, it is necessary to water promptly to lower soil salinity.
3. Disease and Pest Control
Regularly inspect chrysanthemum plants for diseases and pests and treat them promptly. Biological pesticides or low-toxicity pesticides can be used for spraying, avoiding the use of high-toxicity pesticides.
4. Environmental Regulation
Maintain good ventilation conditions, avoid high temperature and high humidity environments, adjust the spacing between plants appropriately, increase sunlight, and enhance the plant's disease resistance.
5. Pruning and Disinfection
Prune weak and diseased leaves in time, remove diseased residues, and regularly disinfect the flowerpots and soil to prevent the spread of diseases and pests.
The reasons for the internal rot of potted chrysanthemum flowers are diverse, but with the correct maintenance methods, it can be effectively prevented and treated.
