Watering is not fixed-point watering like three meals a day, but to judge the soil first, if the basin soil is very dry, the leaves are soft, and the whole plant leaves fall down again, then you can consider watering.
Rieger's Begonia is a plant with relatively high water demand. I don't know if you want to water it if you want to, or if you can't remember, you won't? This can not form a good law of watering.
Lige Begonia should be watered in the morning or in the evening. The times of watering are not several times a day or several days, but depend on the degree of soil moisture.
Beautiful flowers should be carefully cared by the owner, so watering should also be divided into winter and summer. Due to the high temperature, fast evaporation and relatively large water demand in summer, watering should be done in the morning or evening. In winter, water should be done at noon on a sunny day. At the same time, ensure that the water temperature is close to the indoor temperature. The water temperature should not be too cold, or it will stimulate the root to cause necrosis.
Do not over water, if over water, water will fill the soil gap, causing serious soil hypoxia, resulting in root hypoxia death. Too wet pot soil is also easy to give fungi, bacterial disease infection opportunities, so the owners in watering do not love to spend too much water.
