1、 How to raise cold water flowers in winter

1. Raise the temperature: in winter, we should pay attention to providing a warm growth environment for cold water flowers. Because it is not particularly cold resistant, if the temperature is very low, it will be frozen. Specifically, the temperature needs to be maintained above 5 ℃. If you want to breed outdoors, you need to wrap it with film to prevent it from freezing. Every two days at noon, you need to uncover the film and breathe for it

2. Suspend fertilization: in winter, it grows very slowly and does not need additional nutrients, so it does not need to be fertilized

3. Proper water control: in winter, its basin soil should be controlled in a slightly dry state, but its basin soil should not be dry and cracked. It is recommended to water every 15-20 days

4. Give it more sunlight in winter. Because although it is shade resistant, it can grow better in an environment with sufficient light. It is very beneficial for it to spend the winter by extending the time it receives sunshine in winter

At this time, we need to cut off the seriously blackened leaves first, and then spray water around them regularly to increase the humidity of the air. It will recover soon
