1 1 If day lily is planted in the month, will the root seedlings be frozen in winter?

The aboveground part of day lily is not cold-resistant, and the underground part is cold-10℃; When the average temperature of seeds is above 5℃, seedlings begin to emerge, and the optimum temperature for leaf growth is 15℃ ~ 20℃.

In 1 1 month, it is best to plant in a greenhouse or have other insulation measures. If planted outdoors, most areas north of the Yangtze River have dropped below 0 degrees, making it difficult for seeds to germinate. Even if they germinate, there is no suitable growth condition. 1 1 may not freeze to death at the beginning of the month, but it will also become a stiff seedling, which will affect the growth. 1 1 is likely to freeze to death in the middle and late months. Northeast China1may freeze to death at the end of October.

If planted in the south of the Yangtze River, without heat preservation measures, even if it can germinate, it is likely to die from freezing rain.
