What should I do if the temperature of Xiaolei, which has just been hit by Chinese rose, drops by only 5 degrees?

It is suggested to move potted roses to sunny places, but they will not get wet. For example, a balcony facing south or an open corridor facing south. Blue demon suggests that you put it in a shelter from the rain, but the real purpose is to avoid frost. When the temperature is lower than 5 degrees at night, it will frost, and the flower buds of roses are prone to dysplasia and cannot open normally after frost. If we put potted roses in a place where frost can't reach, then after a period of slow growth, the existing buds of roses can generally open normally, and even the flowers will be very standard. Try not to put Chinese rose against the wall, or put it too crowded, and try to avoid corners and keep the environment well ventilated, otherwise it is easy to grow red spiders, which is also very annoying. For potted roses full of flower buds, it is suggested that liquid fertilizer should be applied continuously, but the fertilizer concentration should be reduced. It is best to use fermented organic fertilizer or slow-release fertilizer to promote the growth of flower buds and open them early.

Our Chinese rose needs to grow at a temperature above 5 degrees. When the temperature is below 5 degrees, frost will appear at night. Outdoor roses will not grow well because of frost, and they are easy to get downy mildew. When there is a lot of rain, gray mold will also become a great threat. However, this does not mean that the existing buds of Chinese rose must not be opened, so it can be carefully maintained according to the above methods.
