How cold can Calla lilies tolerate
A small piece of knowledge, sharing with you the small experience of Calla lily cultivation and how much cold they can tolerate. Let's take a look together.
How cold can Calla lilies tolerate
Calla lilies are not cold-tolerant, and can withstand the lowest temperatures of 4 to 5 degrees Celsius. The optimal growth temperature is between 15 to 25 degrees. Temperatures below 5 degrees Celsius will slow down plant growth and cause them to enter a dormant state. In winter care, it is important to strictly control the indoor temperature and keep it above 15 degrees Celsius. Also, place the Calla lilies in a location with good lighting conditions and control watering.
Calla lilies have a high ornamental value and are commonly used as bouquet flowers by brides in Western countries. They are native to Africa. Now they are cultivated in warmer regions such as Fujian, (T-W), and Sichuan in China. They prefer a warm and humid environment, are not cold-tolerant, and fear frost.
Calla lily cold tolerance temperature
1. Growth temperature
Calla lilies prefer a warm, humid, and well-lit environment. They dislike cold and drought. The optimal growth temperature is between 15 to 25 degrees. When summer temperatures exceed 30 degrees or winter temperatures fall below 5 degrees, they will basically enter dormancy.
2. Overwintering temperature
Calla lilies have poor cold tolerance, and temperatures below 5 degrees Celsius will slow down plant growth and cause them to enter a dormant state. In winter care, it is important to strictly control the indoor temperature and keep it above 15 degrees Celsius.
3. Minimum cold tolerance temperature
Calla lilies are not cold-tolerant and can only withstand low temperatures of 4 to 5 degrees Celsius. If the ambient temperature is below 5 degrees, the plants will be forced into dormancy, and if it drops below 0 degrees, the plants may freeze to death.
Overwintering care for Calla lilies
1. Lighting conditions: When cultivating Calla lilies in winter, special attention should be paid to lighting, as the winter sun is weak and the duration of sunlight is short. Therefore, place the Calla lilies in a location with good lighting conditions. Insufficient light may cause the flowering period to be shortened and the flowers to wither prematurely.
2. Water conditions: The evaporation rate of water is slower in winter, so it is important to control the amount of watering. Excessive watering may cause root rot in Calla lilies. Also, the water temperature should be close to room temperature, as water that is too cold may freeze and injure the plants.
3. Precautions: When caring for Calla lilies in winter, prevent cold winds from attacking by moving them to a warm room. When the sun is shining at noon, you can open the windows for ventilation, which will enhance the plant's resistance and effectively prevent diseases and pests.
The above is a specific introduction to how much cold Calla lilies can tolerate. I hope you will like it!
