The best time to water Calendula is in the morning, when the temperature is low, which is beneficial to all aspects. It's not suitable for water supply in the evening. Keep dry in the evening.
To water Calendula, you'd better choose soft water, which contains less minerals and is rich in growth needs, such as lake water, river water, rain water, etc. If you choose tap water, you can't water it directly, but you can put it in the sun for a period of time, and when the chemical components in it evaporate, you can water it in.
When the soil is dry, water supply is required. The amount of water can be moderate, and too much water can not be supplied at one time, so as to ensure that it can be poured through, and too much water can not be supplied at one time, so as to prevent water accumulation and affect root growth.
The water supply frequency is different in different periods. Spring and autumn are just in the growth period. There is a certain demand for water. At this time, the growth is relatively vigorous, and water can be poured every 3-5 days. The temperature in summer is too high. At this time, too much water can not be applied. The water can be supplied every 1-2 weeks. In winter, it will enter into a period of slow growth. Water can be applied once or twice a month. As long as the soil is not very dry, water supply is not required.
