1. North area: In north cold area, many head chrysanthemum needs to move into warm indoor cultivation, otherwise the plant can be frostbitten, therefore is the greenhouse flower in the north area.Its suitable growth temperature is between 15 and 25 degrees.If the temperature falls below five degrees below zero, it will freeze the plant and stop its growth.Long-term exposure to low temperatures of minus 5 degrees will lead to plant death.
2. Southern region: If the temperature in winter in the southern region is not less than 5 degrees below zero, it can be maintained outdoors.For example, in the southern region, the multi-headed chrysanthemum cultivated in the open field of flower beds can survive the winter smoothly without special management.In most parts of the south, the cultivation of chrysanthemum can be done without moving the plants indoors.So in these places, the chrysanthemum belongs to the open field flowers and trees.
1. Northern region: When the temperature is lower than 5 degrees below zero, it is necessary to move the plant to a warm place indoors in time for maintenance.In addition, in winter, we need to reduce the amount of watering, or we can not water, so that the pot soil as dry as possible, in order to avoid excessive water to freeze the soil, affecting the normal growth of plants.When the indoor temperature is still too low, plastic film can be used to cover the plants to keep them warm.
2. Southern region: As long as the temperature is not less than 5 degrees below zero, it can not change its breeding environment, normal maintenance on the line.However, plant growth becomes slower in winter, and the demand for water and nutrients will decrease, requiring less watering and fertilizer application.
