The best way to raise geranium is to use fertile and loose soil.
Its optimal growth temperature is 15-20 ℃, generally speaking, the temperature conditions at home can meet its needs. However, when the weather is cold in winter, we need to take heat preservation measures to keep the temperature at about 10-15 ℃, and the temperature at night should also be above 8 ℃, otherwise it will not be able to bloom normally.
It likes relatively dry growth conditions. Watering for it needs to follow the principle of "see the dry and see the wet". That is to say, before the soil is dry, it does not need to be watered. After the soil starts to dry, it needs to be watered. Usually keep the soil a little dry.
