When can the rose be kept warm?

When the weather is clear, such as noon.

When the sun is shining at noon, you can open the insulation material and ventilate it until evening. Repeat this operation for more than ten days, and then completely remove the insulation material when the weather is really stable.

Take North China as an example. In general, the insulation can be removed in early March.

Rose is a kind of high-quality ornamental flower with strong frost resistance, which is famous for its long flowering period, bright colors, drought resistance and strong soil adaptability.
