How to care for lilies in winter to ensure safe survival
In winter, lilies can be moved to a warm and well-lit indoor area for care. The temperature should not exceed 15℃, or they may bloom prematurely. Since winter temperatures are low, watering should be minimal, only when the soil is completely dry. A small amount of slow-release fertilizer can be applied to store nutrients for blooming the following year, but it should not be overused.
Lilies are heat-sensitive and prefer cool environments. If the ambient temperature can be maintained between 15-25 degrees Celsius in winter, the bulbs will sprout. They can grow and bloom normally in spring, autumn, and winter.
Generally, potted lilies are easy to overwinter, requiring only moving them indoors and maintaining a room temperature above 0℃. They can be placed on a sunny windowsill for care. Below are specific methods and precautions for caring for lilies in winter.
Adjust according to local conditions
To ensure lilies survive winter, it is important to understand how they overwinter. It is easier for lilies to overwinter in the north than in the south, and methods should be adapted to local conditions. For potted lilies, simply move the pot to a greenhouse when winter arrives, which is not necessary in the south.
Suitable temperature
The indoor temperature in the greenhouse should be maintained above 0℃. If possible, place the pot on a windowsill with plenty of sunlight.
In the cold winter weather, exposing lilies to sunlight daily can mix the warmth of the sun with the surrounding low temperature, preventing the temperature around the lilies from being too cold.
Avoid heat sources
Lilies should be kept away from heat sources such as air vents, stoves, and空调 outlets. This can cause the lilies to awaken from dormancy, leading to confusion in blooming and affecting the quality of the flowers.
Lilies require a period of about 45-100 days of low temperature before blooming to ensure a more beautiful display. Therefore, during the low-temperature period in winter, the temperature around the lilies should not be too high to affect their normal growth.
Water appropriately
During the winter, ensure that the soil in the pot remains slightly moist. Sometimes a small amount of water can be added, but avoid overwatering, which can cause waterlogging and possibly lead to root rot. Regularly misting the leaves is sufficient.
Use plastic film for insulation
If lilies are overwintering in the south, they do not need to be moved indoors for warmth. Instead, a layer of plastic film can be placed over the entire plant. On sunny days, the plastic can be removed to allow for ventilation and sunlight. When temperatures stabilize above 0℃, the film can be removed.
The above introduces some tips on how to care for lilies in winter to ensure safe survival. I hope this article is helpful to you!
