Kalanthus is a popular potted plant, and its beautiful flowers and hardy properties make it ideal for many homes. However, sometimes kalanchos lose their leaves, which can be bothersome for conservationists. Here's what causes longevity flowers and how to remedy them.
1. Cause analysis.
1.Too much or too little water: Longevity flowers have a higher need for water, and too much or too little water can lead to leaf loss. If the soil is too wet, the root system is prone to rot, causing the leaves to fall off; Lack of water will cause the plant to lack water and the leaves will turn yellow and fall off.
2.Improper fertilization: Too much or too little fertilization can adversely affect the growth of longevity flowers. Excessive fertilization can cause roots to burn, and the leaves will turn yellow and fall off; Insufficient fertilization can deprive plants of essential nutrients, leading to poor growth and leaf loss.
3.Lack of light: Longevity flowers need plenty of light for photosynthesis, and if there is not enough light, the leaves will turn yellow and fall off.
4.Pests and diseases: When long-lived flowers are attacked by pests and diseases, they may lose their leaves. Such as leaf spot, aphids, etc.
2. Remedial measures.
1.Control moisture: When watering, the principle of "seeing dry and wet" should be followed to keep the soil moist and free of waterlogging. In the rainy summer season, attention should be paid to drainage to avoid over-wetting the soil. In winter, it is necessary to reduce watering appropriately and keep the soil dry.
2.Reasonable fertilization: When fertilizing, the principle of "thin fertilizer and diligent application" should be followed, and nitrogen, phosphorus and potassium compound fertilizer or well-rotted organic fertilizer should be used for fertilization. Avoid using thick or raw fertilizer to avoid burning the roots. In the peak growing season, the number of fertilization can be appropriately increased, and in winter, fertilization should be reduced or stopped.
3.Increase light: Place kalancho flowers in a well-lit area and receive at least 6 hours of direct sunlight every day. If you are in a dark environment for a long time, you need to gradually increase the light to avoid sunburn caused by exposure to strong light all at once.
4.Pest control: Regularly inspect the leaves and branches of longevity flowers, and take timely control measures if pests and diseases are found. For common diseases such as leaf spot, carbendazim, chlorothalonil and other agents can be used for prevention and control; For common pests such as aphids, imidacloprid, avermectin and other agents can be used for control.
5.Replace the potting soil: If the soil is too wet or too dry, or if the potting soil has not been changed for a long time, consider changing the potting soil. Choose potting soil with good air permeability and good drainage, you can use peat soil and perlite in a 1:1 ratio, and then add an appropriate amount of well-decomposed organic fertilizer as the base fertilizer. When replacing the potting soil, care should be taken not to hurt the root system, and after the replacement, water thoroughly and place it in a ventilated place for maintenance.
In conclusion, the loss of leaves in longevity flowers may be due to problems with moisture, fertilizers, light, pests and diseases, etc. By controlling moisture, fertilizing properly, increasing light, controlling pests and diseases, and replacing potting soil, the problem of leaf loss can be effectively solved and longevity flowers can be rejuvenated. At the same time, in the daily maintenance, we should also pay attention to the growth of plants, find problems in time and take corresponding measures to remedy them.
