1、 Soil

Loose and breathable soil should be used. The culture soil can be mixed with humus soil, peat soil, perlite and organic fertilizer. It is best to turn the basin once in autumn

2、 Watering

Watering should be appropriate. The spring and autumn season is its peak growth period. At this time, sufficient water should be maintained. The basin soil should be in a wet state, but do not produce ponding; Reduce the amount of water when the temperature is low; If there are many rainy seasons, drainage measures should be taken to avoid ponding and root rot. it should be placed in a dry and ventilated place; In winter, the indoor temperature is relatively low, so it is necessary to water less

3、 Temperature

The temperature suitable for the growth of geranium is 15-25 ℃. In winter, the indoor temperature is best controlled at about 10 ℃, not lower than 3 ℃. If it is lower than this temperature, it will be subject to cold damage. Some varieties can accept the low temperature of 0 ℃. The maximum temperature should not exceed 35 ℃. Once it is in a high temperature environment, it will enter a semi dormant state. Keep it in a ventilated environment as far as possible and avoid muggy breeding environment

4、 Illumination

Geranium needs to be exposed to sufficient sunlight, but shading measures should be taken when the sunlight is too strong in summer. It can be exposed to sunlight in other seasons. If the sunlight is insufficient, it will not bloom. When flowering, it should avoid direct sunlight. It can be moved to the indoor appearance, and can be put back to the place with light after flowering. Turn the basin as much as possible to make the light on the leaf surface more uniform
