Water yemen iron once every few days.

We should water it according to the temperature, climate and region. Generally, when the weather in the north is dry in winter, it must be watered thoroughly, usually once every 10 day. It's humid in the south, so you can water it a little more, usually about 15 days. The principle of watering it is to water it less or not more. Water every 4-5 days in other seasons.
