1、 Afraid of the cold

Gardenia is afraid of cold and difficult to survive in a subzero environment. In a low temperature environment, branches and leaves will have varying degrees of frostbite, which will have an adverse impact on beauty and later growth. Among them, gardenia grandiflorum is a relatively cold resistant variety, which can accept the low temperature of minus 1-3 degrees. However, the lower the temperature, it will have an impact, resulting in freezing injury. Therefore, it is necessary to prepare for overwintering, move the plant indoors for maintenance in time, and contact sufficient sunshine to increase the temperature of the plant and keep it at about 10 degrees. Even if it is placed outdoors, it can also be covered with a bag for insulation

2、 How to deal with frostbite

If frostbite occurs accidentally, it needs to be handled in time. First observe the condition of the plant. If the frostbite is mild, cut off the frostbite part first, and then gradually increase the surrounding temperature with appropriate water spraying. Be careful not to put it in a place with high temperature immediately, otherwise the plant will be difficult to adapt for a while

If it is observed that the plant is severely frostbitten, dig out the roots first. If the roots are fresh, trim the upper branches, cut off the redundant branches, and then replant. After planting, place it at a suitable temperature and wait for germination. Do not touch strong light
