Gerbera daisies, also known as Transvaal daisies or African daisies, are beautiful flowering plants that add a vibrant touch to any garden or landscape. However, when it comes to surviving winter, these daisies can be a bit tricky. Let’s delve into the details.
1. Frost Sensitivity:
Gerbera daisies are frost-sensitive perennials, meaning they are not able to withstand freezing temperatures. When exposed to frost, their leaves and stems can become damaged, leading to the decline and potential death of the plant.
2. Mild, Frost-Free Winters:
In areas with mild, frost-free winters, gerbera daisies can thrive and bloom year-round. They enjoy moderate temperatures ranging between 60-75°F (15-24°C) and prefer bright, indirect sunlight. These conditions are often found in regions with a Mediterranean or subtropical climate.
3. Protection during Winter:
If you live in an area with occasional frost or mild winters, you can take some precautions to help your gerbera daisies survive the colder months. Here are some tips:
A. Mulching: Apply a layer of organic mulch around the base of the plants, such as straw or wood chips. This will help insulate the soil and protect the roots from extreme temperatures.
B. Covering: Use a frost cloth or blanket to cover the plants during frosty nights. Secure the cover tightly around the plant, ensuring it reaches the ground. This will create a mini greenhouse effect, trapping heat and protecting the daisies from freezing temperatures.
C. Container Gardening: If you grow your gerbera daisies in containers, you have the advantage of being able to move them indoors during cold snaps or winter months. Place them in a sunny location, such as a sunny window, and continue providing them with proper care.
D. Greenhouse: If you have access to a greenhouse, you can transfer your gerbera daisies indoors during winter. Greenhouses provide a controlled environment with optimal temperature and protection from frost, allowing the daisies to continue growing and blooming.
4. Harsh Winters:
In regions with harsh winters, where temperatures consistently drop below freezing for extended periods, gerbera daisies are unlikely to survive outdoors. In such cases, it is best to treat them as annuals or consider growing them as houseplants instead.
5. Indoor Care for Winter:
If you decide to bring your gerbera daisies indoors for the winter, here are some guidelines to ensure their well-being:
A. Lighting: Place the plants in a location that receives bright, indirect sunlight. South-facing windows are usually ideal.
B. Temperature: Maintain a temperature range between 60-75°F (15-24°C) indoors. Avoid placing the plants near drafts or heating vents, as extreme temperature fluctuations can stress the daisies.
C. Watering: Water your gerbera daisies thoroughly, allowing the excess water to drain out. Avoid overwatering, as it can lead to root rot. Allow the top inch of soil to dry out slightly between waterings.
D. Humidity: Gerbera daisies appreciate slightly higher humidity levels. You can increase humidity by placing a tray filled with water near the plants or using a humidifier.
E. Fertilization: During winter, when the plants are not actively growing, reduce the frequency of fertilization. Use a balanced, water-soluble fertilizer at half the recommended strength every 6-8 weeks.
By understanding the frost sensitivity of gerbera daisies and taking appropriate measures, you can increase their chances of surviving winter or enjoy their blooms indoors throughout the year. Remember to adapt these guidelines to your specific climate and growing conditions.
