How to Care for Daisies in Winter
As winter approaches, the most concerning issue for gardening enthusiasts is the care of potted flowers. Daisies, with their vibrant colors and tenacious vitality, are deeply loved, but the low temperatures of winter can easily cause frost damage or even death to the plants. This article will provide a detailed analysis of the core care techniques for daisies to survive winter, focusing on environmental control, water and fertilizer management, and light optimization.
Key Points of Environmental Control
Indoor Placement Strategy
When the temperature drops below 10℃, it is recommended to move the potted plants to an indoor window sill or a closed balcony. Avoid placing them within 3 meters of air conditioner outlets or radiators and maintain good air circulation. A special reminder for northern gardeners: the temperature near the window at night may drop sharply, so consider wrapping the pot with a thermal cotton cover.
Golden Range of Temperature and Humidity
Maintaining a growth temperature of 16-22℃ with 50%-60% air humidity is ideal. You can place a humidifier tray near the plant and use a thermometer and hygrometer for real-time monitoring. If the room temperature is below 5℃ for more than 48 hours, consider building a temporary greenhouse covered with transparent plastic film.
Tips for Water and Fertilizer Management
Adjustment of Watering Frequency
In winter, extend the watering cycle to 15-20 days per time, using the immersion method to supplement water more safely. Control the amount of water given to one-third of the summer amount and water again only when the potting soil is completely dry. Especially in temperatures below -3℃, stop watering completely.
Nutrient Supply Plan
Pause the application of nitrogen fertilizer from November to February of the following year and supplement phosphorus and potassium fertilizers once a month (diluted to half the normal concentration). It is recommended to use a special slow-release fertilizer for flowers, spreading 5-8 granules on the surface of the potting soil is enough to meet the nutrient needs during winter.
Light Optimization Plan
In winter, ensure at least 4 hours of direct sunlight daily, and extend it to 8 hours using grow lights. Rotate the pot every 3 days by 45 degrees to ensure even light exposure. After rain or snow, promptly wipe the leaves to maintain light transmission and avoid dust affecting photosynthesis.
By scientifically controlling the temperature, precisely managing water and fertilizer, and rationally configuring light, not only can daisies survive the winter safely, but they can also accumulate energy for a bloom爆发 in spring. It is recommended to regularly check the condition of the plants and adjust the care plan in a timely manner to keep this winter flower beauty on the windowsill.
