Lilies are perennial herbs, so they will not die in winter as long as they are given suitable environment. However, at this time, the temperature is relatively low, especially in the north, the above ground part is usually dried up due to the low temperature environment, but the underground bulbs can survive the winter safely, so they should be moved to the greenhouse. The south is relatively warm and can be spent outdoors. When the temperature rises in spring, it will grow and sprout normally.
1. Temperature: if you want it to survive the winter, you should first ensure the temperature, which should be above 10 degrees, so that the bulbs can be safely spent. If the temperature is low, it can be refrigerated and put in the sand for heat preservation to avoid freezing.
2. Light: the light in winter is mild. If conditions permit, it can be placed on the balcony indoors. More sunlight can also alleviate the low temperature environment, which is beneficial for winter.
3. Watering: it needs to control the water during the winter. At this time, it is dormant and stops growing. If there is too much water, it is easy to accumulate water and rot roots. Basin soil a little bit wet on the line, if it is too dry at noon a small amount of water.
4. Heat preservation: if it's in the south, just put it outside. It can cover the outer layer of the plant with plastic film for heat preservation. When the weather is sunny, it can be opened for sun exposure. After the temperature is stable, it can be completely removed.
