1. According to the size of the plant

For a seedling, the method of "small amount but high frequency" is generally adopted to water it. It can be watered once a day, but not too much. However, for adult plants, the method of "more water at one time and longer interval" is generally adopted. It can be watered once a week or so, but the amount of watering is more. If it is an old pile, it should be poured directly once or twice a month

2. According to the state of the soil

This is also a good way to judge whether it needs watering. Due to different factors, the time of soil drying will be different. If the soil is observed to be dry, it can be watered next time

3. According to the change of season

The frequency of watering is naturally different in different seasons. The frequency of spring and autumn is almost the same, almost once a week. If the ventilation is good, it can be once every three or four days. In summer, plants will dormant at high temperature, and the frequency should not be too high. Generally, it is once every half a month to 20 days. Low temperature in winter will also hibernate, and the frequency is similar to that in summer

4. According to soil and container

If the soil contains more particles, the water permeability will be relatively good, so the watering interval should be shortened. The impact of containers is also great. If potted pottery plants are used, it is easy to lack water. The size also has an impact. The volatilization speed of large caliber is fast, so the watering interval is also short
