As winter approaches, many flower enthusiasts find that their potted osmanthus, which used to be fragrant, seems to have lost its aroma in winter. Why does the potted osmanthus not have a strong fragrance in winter? This article will reveal the maintenance mistakes and provide corresponding solutions.
Insufficient Lighting
Osmanthus loves light, and adequate sunlight is an important factor in ensuring its fragrance. In winter, due to the shortened daylight hours and weakened light intensity, the potted osmanthus does not receive enough light, leading to weakened photosynthesis, which affects the synthesis of fragrance substances. In winter, the potted osmanthus should be placed in a sunny area, such as a south-facing windowsill.
Improper Watering
Osmanthus requires a lot of water, but due to the low temperature in winter, water evaporates slowly. Overwatering can easily lead to root rot, and uneven watering can also affect the fragrance. In winter, watering should follow the principle of "water when dry and keep moist," maintaining slightly moist soil.
Low Temperature
Osmanthus prefers a warm and humid environment. Low temperatures in winter can cause the leaves of the osmanthus to turn yellow and fall off, affecting the fragrance. In winter, the potted osmanthus should be placed indoors, maintaining a room temperature above 10°C.
Improper Fertilization
Osmanthus needs plenty of nutrients during the growing season, but fertilization should be reduced in winter to avoid affecting its dormancy. Over-fertilization in winter can lead to excessive growth of osmanthus, affecting the fragrance. In winter, some phosphorus and potassium fertilizers can be applied appropriately to promote the synthesis of fragrance substances in osmanthus.
Pest and Disease Control
Winter is a high incidence period for osmanthus pests and diseases. If not treated in time, it will affect their growth and fragrance. Common pests and diseases include aphids and red spiders. Control methods include: regularly inspecting the plants and removing pests and diseases in a timely manner; using low-toxicity and low-residue pesticides for control.
Solutions:
1. Adjust lighting: Place the potted osmanthus in a sunny area, such as a south-facing windowsill, to ensure it receives adequate light.
2. Control watering: Follow the principle of "water when dry and keep moist," maintaining slightly moist soil.
3. Adjust temperature: Place the potted osmanthus indoors, maintaining a room temperature above 10°C.
4. Fertilize properly: Apply phosphorus and potassium fertilizers appropriately in winter to promote the synthesis of fragrance substances.
5. Strengthen pest and disease control: Regularly inspect the plants, remove pests and diseases in a timely manner, and use low-toxicity and low-residue pesticides for control.
The reasons why the potted osmanthus does not have a strong fragrance in winter are multifaceted. By adjusting the maintenance methods, the fragrance can be effectively improved. I hope this article can bring more fragrance and beauty to your potted osmanthus.
