1、 It can be opened in winter

Climbing roses can bloom in winter. But not all places will open. Generally speaking, climbing rose is planted in the ground, so if it is in a place with high latitude and it is very cold in winter, it will not bloom basically. However, if it is in a low latitude area or cultured indoors as a potted plant, it may also bloom. However, there are too many restrictive factors in winter, and it needs good maintenance to bloom

2、 How to promote flowering

1. Temperature: if the limiting condition of low temperature is solved, flowering will not be particularly difficult. However, for ground plants, there is no way to move to indoor maintenance, which is more troublesome. Other measures can be taken to prevent cold and keep warm, such as covering with plastic film and so on

2. Light: light is also an important limiting factor. If it is planted on the ground, try not to block the sun and let it receive more light. If you are indoors, you also need to receive more light to find the brightest place. It's easy to promote its flowering

3. If there is not enough nutrients for flowering, it is not easy to store. Therefore, some fertilizer can be used to promote flowering. However, the type of fertilizer needs to be selected well. Only phosphorus fertilizer and potassium fertilizer can have an effect on flowering
