How to Help a Calla Lily Survive Winter
Today, our editor will delve into the cold tolerance of calla lilies and provide tips for ensuring their safe wintering, as well as highlight key points for winter care. This information will surely be of help to you, so let's take a look together!
Calla Lily Cold Tolerance
The calla lily is not cold-tolerant; it can withstand a minimum temperature of 4°C. During winter care, if the room temperature is 15°C, it is necessary to keep the night temperature above 10°C for the plant to bloom.
Calla lilies can freeze to death in winter, so it is important to protect them from the cold. The most suitable growth temperature for the plant is around 20°C, and it can freeze at temperatures below 0°C.
Safely Overwintering Calla Lilies
1. Fertilizer: Calla lilies also need to absorb nutrients in winter. Therefore, it is essential to apply appropriate fertilizer to the soil before winter. It is recommended to use diluted compound fertilizer to meet the plant's various nutrient needs during the winter.
2. Watering: Calla lilies are not cold-tolerant and should not be watered frequently in winter. The water temperature should be close to room temperature to prevent plant frostbite. Watering can be done once every two weeks, but avoid waterlogging.
3. Outdoors: Calla lilies cannot survive outdoors in winter due to the low temperatures, which are often below freezing. It is important to move the plants indoors to maintain a temperature above 15°C.
4. Northern Regions: Calla lilies can survive in the north, but precautions must be taken to insulate them from the cold. They need to be kept indoors because the outdoor temperatures in the north can be well below freezing, easily killing the plants.
Key Points for Winter Care of Calla Lilies
1. Sufficient Sunlight: Winter sunlight is weak, and calla lilies enjoy being exposed to it. Therefore, they should be placed in a location that receives ample light, especially if kept in a room. It's best to place them near a south-facing window or on a balcony for sufficient sun exposure.
2. Appropriate Temperature: The ideal temperature for growing calla lilies is around 20°C. Low temperatures can easily cause frostbite, so if grown outdoors, insulation measures must be taken.
