1、 Slight frostbite

Symptoms: there are signs of frostbite at the beginning, and individual leaves will be hydrated, become shriveled and tend to be transparent

Treatment: slight frostbite is not very serious, nor is it a large-scale frostbite. It's just a case of individual leaves, so you don't need to worry too much. As long as the maintenance environment is changed and the temperature is maintained at about 10 degrees Celsius, no less than 0 degrees Celsius, the plants can still survive, but the frostbitten ones can't recover, and the water will fall down

2、 Severe frostbite

Symptoms: most of the leaves and stems of the whole plant will have signs of frostbite, and the leaves will become transparent, even gray and black, affecting the ornamental

Treatment method: deal with it in two cases. If the stem is not transparent, remove the frostbitten leaf, and then put it in a bright and ventilated place at 10 ° C for about a week. During this period, you can't water it and wait for it to survive. If the stem begins to become transparent and softened, cut off the position of the stem, apply carbendazim, and then place it for observation
