How to grow calla lilies to safely survive the winter
Let me share some tips on how to grow calla lilies to ensure they survive the winter safely. Regarding the care and wintering of calla lilies, here is a comprehensive introduction.
1. Fertilization: Calla lilies still need to absorb nutrients in winter, so it's essential to apply appropriate fertilizer to the soil before winter. It is recommended to use diluted compound fertilizer to meet the various nutrients calla lilies need during the winter.
2. Watering: Calla lilies are not cold-resistant, so they should not be watered frequently in winter. The water temperature should be close to room temperature to avoid frostbite. Watering once every two weeks is sufficient, but avoid waterlogging.
3. Outdoors: Calla lilies cannot survive outdoors in winter, as the outdoor temperature is too low, often below zero. It's important to move the plants indoors for care, maintaining a temperature above 15 degrees Celsius.
4. Northern regions: Calla lilies can survive in the north, but precautions must be taken to keep them warm. They need to be kept indoors because the outdoor temperature in the north can be well below zero, easily freezing them.
The above information is a specific guide on how to grow calla lilies to safely survive the winter and how to help them through the winter, for everyone's reference.
