Potted flowers are mostly dormant during the winter and their growth is slow, their metabolism is reduced, and their water requirements are reduced accordingly. If the water is not well controlled, root frostbite will appear. As a result, the upper part of the plant withered or even died.
Watering in winter is best before and after noon (usually between 10 a.m. and 2 p.m.), where water temperature and temperature are appropriate. If the water temperature is too low, causing freezing damage, it is difficult to recover. Therefore, watering in winter must be able to grasp the watering time and water less. The amount of potted flowers entering the greenhouse is determined by the temperature in the greenhouse. Potted plants in low-temperature greenhouses are watered once every 4-5 days, and potted plants in medium-temperature greenhouses and high-temperature greenhouses are usually watered once every 1-2 days. When there is plenty of sunlight and higher temperatures, the amount of watering is more.
Because of the heating equipment in the greenhouse, the air is easy to dry, so for those flowers that are high in temperature and humidity, besides watering, water spray is also needed to increase the humidity in the air.
In the event of a strong wind whistling and cold air invading, flowers on the outside need to be kept warm and less watered.
