With the arrival of winter, many flower enthusiasts find that the leaves of osmanthus they raise indoors begin to show signs of withering. This not only affects the beauty of osmanthus but also raises concerns about the health of the plant. Why do the leaves of indoor osmanthus wither in winter? How should maintenance be carried out? This article will answer these questions for you one by one.
Reasons for the withering of osmanthus leaves indoors in winter1. Insufficient water
Osmanthus is native to southern China and prefers a humid environment. In winter, the indoor air is dry and the humidity is low, making it easy for osmanthus leaves to lose moisture, leading to withering.
2. Insufficient sunlight
Osmanthus loves sunlight. In winter, the day is short, and indoor sunlight is insufficient, which weakens the photosynthesis of osmanthus leaves, prevents normal growth, and results in withering.
3. Low temperature
The suitable growth temperature for osmanthus is between 15-30°C. If the indoor temperature in winter is too low, the leaves of osmanthus are prone to frost damage, leading to withering.
4. Improper fertilization
Excessive or improper fertilization can lead to poor growth of osmanthus leaves and cause withering.
Maintenance tips for osmanthus leaves indoors in winter1. Maintain appropriate humidity
The main reason for the withering of indoor osmanthus leaves in winter is insufficient moisture. To maintain indoor air humidity, the following methods can be used:
(1) Use a humidifier to increase indoor humidity;
(2) Spray water on the osmanthus leaves every day to keep the leaves moist;
(3) Place the osmanthus near a water source, such as a bathroom or kitchen.
2. Increase sunlight appropriately
Place osmanthus in a place with sufficient sunlight, such as a windowsill or balcony. Since sunlight is short in winter, artificial lighting can be provided, such as using plant growth lights, to ensure the normal growth of osmanthus.
3. Control temperature
Keep the indoor temperature between 15-30°C to prevent frost damage to osmanthus.
4. Fertilize properly
In winter, osmanthus grows slowly, and fertilization should be moderate. Compound fertilizer or organic fertilizer can be used, and fertilize every 20 days.
5. Prune branches and leaves
Timely pruning of withered and yellow leaves is beneficial for the growth of osmanthus and also helps maintain the beauty of the plant.
Withering of indoor osmanthus leaves in winter is a common problem. Understanding the reasons and taking corresponding measures can effectively prevent it. It is hoped that this article can provide help for your osmanthus maintenance.
