1、 Cold resistant

Multi headed chrysanthemum has strong cold resistance. When the flower bed is cultivated in the open field, the temperature is more than - 5 degrees below zero to survive the winter safely. However, if you grow in a low temperature environment below minus 5 degrees for a long time, the leaves of the plant will be frostbitten and become dry and yellow. In serious cases, the plant will freeze to death. After the temperature rises, the plant can germinate new leaves, breed flower buds and bloom. During daily maintenance, try to keep the temperature of the plant growth environment between 15-25 degrees

2、 How to spend the winter

1. Temperature: the climate in the South and north is quite different, so the methods of winter will be different. When the temperature in the south is not lower than minus 5 degrees, the plants can continue to be placed outdoors for maintenance. When the multi headed chrysanthemum withers, the branches need to be trimmed in time. Prune the branches about 20cm away from the soil, and then water them, which can reduce the consumption of nutrients. The weather in the north is cold, so the plants must be moved into a warm place indoors for maintenance to make them survive the winter smoothly. Ground grown multi headed chrysanthemums need to cover the plants with plastic film or hay to keep them warm

2. Watering: in winter, the growth of plants enters the dormancy period, the growth speed becomes slow, and the demand for water will be low. Therefore, it is necessary to reduce the number and amount of watering, keep the soil dry, and prevent the plant from frostbite caused by too much water

3. Fertilization: after the chrysanthemum withers in winter, there is basically no need to increase fertilizer. However, it needs to be treated according to different varieties. Because some multi headed chrysanthemums bloom in December, it is still necessary to supplement nutrients in time to facilitate plant flowering
