Whether the blue snow flower can overwinter outdoors depends mainly on the temperature conditions in the area.

1. Cold resistance

Blue snow flower has a certain degree of cold resistance, but is not cold-resistant. In warm areas in the south, if the winter temperature can be maintained above 0 degrees Celsius, blue snow flowers can overwinter outdoors. However, in northern regions, since the winter temperature is below 0 degrees Celsius for a long time, blue snow flowers need to be moved indoors to overwinter to avoid frostbite.

2. Temperature requirements

The ideal growth temperature for blue snow flower is between 15-28℃. Below 7℃, the growth of blue snow flowers will stop, below 5℃ will cause cold damage, and around 0℃ all the leaves will fall off. Therefore, except for the Lingnan region, blue snow flowers need to be moved indoors for maintenance in other regions in winter.

3. Wintering measures

If the blue snow flower needs to overwinter outdoors, you can take some warming measures, such as covering the roots with straw or old clothes to avoid freezing. For potted blue snow flowers, adult plants can overwinter outdoors if the winter temperature does not drop below zero degrees. It is recommended to move new plantings or seedlings indoors.

4. Lighting requirements

Blue snow flower likes sunshine and needs more sun exposure in winter. Adequate light is beneficial to the accumulation of plant nutrients and safe wintering.

5. Watering and fertilizing

In winter, the growth rate of blue snow flowers will slow down and consume very little water, so you need to reduce watering, and do not water unless the soil is dry, and keep the soil slightly dry. At the same time, fertilization should be stopped in winter to avoid fertilizer damage.

To sum up, whether blue snow flowers can overwinter outdoors depends mainly on temperature conditions. In southern regions with higher temperatures, blue snow plants may be able to overwinter outdoors, but in cold northern regions, it is recommended to move blue snow plants indoors for maintenance.
