In general, by the end of autumn, we should move the phoenix eye blue indoors. At this time, it should be no less than five degrees Celsius to ensure that the plants will not be too cold. However, it is not realistic to make the water reach the suitable standard of length. We can protect the plants by increasing the room temperature.
In order to supply fresh air to plants, it is best to keep windows open and ventilate every day. However, the time should not be too long, to avoid a large number of low temperature gas into, resulting in low indoor temperature.
This kind of flower also needs a lot of light. It's better to go up and down for four or five hours every day. It is an important factor to ensure that it can survive the winter safely by strengthening the light in winter. When the sun is abundant, move the phoenix eye blue to the balcony and other places to receive the light. Don't forget to move the plants back to the room when the sun sets. If the outdoor temperature is too low, you can put it indoors and open the curtains.
Winter should not be more watering, but can be appropriate to increase indoor air humidity. In addition, it is not suitable to add more fertilizer in winter.
There are different wintering methods in different areas. If it is in the south, it can survive naturally. Winter wilting is a natural phenomenon, you don't have to worry too much. It is suitable for planting in a higher temperature, generally 25-30 ℃ is the best temperature. So, in the cold area or the south area with high altitude, every late autumn and winter, if not managed, the phoenix eye blue will be frozen, the leaves will turn yellow, and may die.
