What is the lowest temperature that camellias can tolerate?
Most camellias have strong cold tolerance and can withstand temperatures as low as -8 degrees Celsius, allowing them to naturally overwinter. However, if the temperature drops below -8 degrees, they may suffer frostbite or die. When temperatures are below 0 degrees Celsius in winter, camellias can be moved to a warm place indoors with plenty of sunlight. Since daylight hours are shorter in winter, they can be kept in full sunlight.
Camellias are one of China's top ten famous flowers and are also known worldwide. They are loved for their graceful plant shape, dark green leaves, and beautiful flowers. Their blooming season is in winter and spring. Although camellias are cold-tolerant, they still need to be kept warm to extend their blooming period and enhance their ornamental value.
How low a temperature can camellias tolerate?
Most camellias have strong cold tolerance and can withstand temperatures as low as -8 degrees Celsius, allowing them to naturally overwinter. However, if the temperature drops below -8 degrees, they may suffer frostbite or die. Therefore, for camellias grown in pots at home, the temperature should be kept above 0 degrees.
Key points for camellias to overwinter
1. Light
When temperatures drop below 0 degrees Celsius in winter, camellias need to be protected from frost and kept warm. They can be moved to a warm place indoors with plenty of sunlight. Since daylight hours are shorter in winter, they can be kept in full sunlight.
2. Watering
Camellias prefer a moist environment but do not tolerate waterlogging. In winter, it is best to spray the leaves of camellias every 3-5 days to increase humidity and clean the leaf surface. Note that the water temperature should be close to the room temperature and not use cold water directly.
3. Fertilizing
Camellias are fond of fertilizer and bloom in winter. Therefore, it is important to fertilize frequently during this period, mainly with thin fertilizer, once every 30 days with a dilute fertilizer. To promote better growth of the flower buds, additional phosphorus and potassium fertilizers can be applied, with less nitrogen fertilizer.
4. Temperature
Camellias prefer a warm environment and are not cold-tolerant. In winter, they should be planted indoors or in a warm, sheltered outdoor area. The indoor temperature should be maintained between 10-15 degrees Celsius. Temperatures below 5 degrees Celsius or consistently above 16 degrees Celsius can cause the leaves and flowers of camellias to wither. Properly caring for camellias in winter will result in blooming in February or March of the following year.
