If the seedlings are watered, the method of "less quantity and high frequency" is generally adopted. You can water it once a day, but not too much. However, for mature plants, the method of "watering more at one time with a long interval" is generally adopted. You can do it once a week or so, but there is more water at a time. If it is an old pile, water it directly once or twice a month.

2, according to the state of the soil

This is also a good way to judge whether it is necessary to water. Due to various factors, the drying time of soil will be different. If you observe the soil is dry, you can water it next time.

3. According to the change of seasons

The frequency of watering in different seasons is naturally different. The frequency of spring is similar to that of autumn, almost once a week. With good ventilation, you can do it once every three or four days. When the temperature is high in summer, plants will sleep, and the frequency should not be too high, usually once every half a month to twenty days. I also sleep when the temperature is low in winter, and the frequency is similar to that in summer.

4, according to the soil and container

If there are more particles in the soil, the water permeability will be relatively good, so the watering interval should be shortened. Containers also have a great influence. If it is potted, it is easy to lack water. Scale is also important. Large-caliber evaporation speed is fast, so the watering interval is short.
