What if you grow vegetables on the balcony and water them once a few days?

It is difficult to answer the question of watering vegetables on the balcony once a few days, for example, watering once every three days, this may be right or wrong, watering for three days in different seasons may cause the vegetables on the balcony to dry up or rot the roots, for example, watering for three days in summer will definitely dry the vegetables, if it is watering for three days in spring, it will rot the roots and die due to the soil being too wet. For example, watering for three days on rainy days or cloudy days is easy to cause water to rot and root death, for example, watering for three days on sunny days is easy to cause soil water shortage and dry death, so it is very difficult to answer the question of watering once a few days, because of its many factors, such as climate, season, soil, biological characteristics of sparse vegetables and other factors will affect the time of watering, the best watering method is to look at the topsoil on the surface, when the topsoil is a little whitish can be watered, and the topsoil should not be watered when it is wet. This is what is often said to be the watering method of not drying, not watering, and watering thoroughly when dry.

Note: Please forgive me for answering wrong, do not accept the correct answer, thank you.

If it is a sunny balcony, it is generally enough to water it once in the morning or evening during this season.
