The wintersweet is a traditional ornamental flower in China, with its pure white flowers and strong fragrance, which are deeply loved by people. In the process of maintenance, many flower enthusiasts find that the leaves of wintersweet will turn yellow and white, which not only affects the ornamental value of wintersweet but may also affect its growth. This article will provide a detailed analysis of the reasons for the yellowing and whitening of wintersweet leaves and the corresponding solutions to help solve this problem.
Reasons for the yellowing and whitening of wintersweet leaves1. Insufficient light
wintersweet likes plenty of sunlight. If it is in a dark environment for a long time, it will lead to yellowing and whitening of the leaves. This is because the lack of light prevents the leaves from carrying out normal photosynthesis, which in turn affects the plant's growth.
2. Improper watering
Watering is a key step in maintaining wintersweet. Excessive or insufficient watering can cause leaves to turn yellow and white. Excessive watering can cause soil waterlogging, leading to root hypoxia and affecting the plant's nutrient absorption; while insufficient watering will make the soil dry, causing the leaves to lose water and turn yellow and white.
3. Soil problems
The acidity, alkalinity, and fertility of the soil will affect the growth of wintersweet. If the soil is too acidic or alkaline, or the fertility is insufficient, it may lead to yellowing and whitening of the leaves.
4. Diseases and pests
Diseases and pests are also one of the reasons for the yellowing and whitening of wintersweet leaves. Common diseases and pests include aphids and red spiders, which absorb the nutrients of the plant, causing the leaves to turn yellow and white.
5. Unsuitable temperature
The suitable temperature for the growth of wintersweet is between 15℃ and 25℃. Too high or too low temperatures will affect its growth, leading to yellowing and whitening of the leaves.
Solutions for the yellowing and whitening of wintersweet leaves1. Adjust light exposure
Move the wintersweet to a place with sufficient sunlight to ensure at least 4 hours of direct sunlight per day. If it is maintained indoors, a desk lamp or fluorescent light can be used to supplement the light.
2. Water appropriately
Water according to the dryness and wetness of the soil. Generally, keeping the soil slightly moist is sufficient. Avoid waterlogging when watering to prevent root hypoxia.
3. Improve the soil
Adjust the soil according to its acidity, alkalinity, and fertility. Organic fertilizers such as chicken manure and sheep manure can be applied to improve soil fertility.
4. Control diseases and pests
Regularly inspect the wintersweet and deal with diseases and pests in a timely manner. Pesticides and fungicides can be used for prevention and treatment, while maintaining good ventilation to reduce the occurrence of diseases and pests.
5. Adjust the temperature
Place the wintersweet in a suitable temperature environment and avoid high or low temperatures. In winter, devices such as heaters or electric blankets can be used to increase the room temperature.
There are many reasons for the yellowing and whitening of wintersweet leaves. Flower enthusiasts should pay attention to the above aspects during maintenance. By adjusting the maintenance measures reasonably, this problem can be effectively solved, allowing the wintersweet to regain its vitality.
