Geranium likes dryness and wetting, winter watering should not be too much, it should be wet between the dry. Wet soil has soft stems and is not conducive to the initiation and opening of flowering branches. Long-term over-wetness will cause the plants to grow in length, and flowering branches will move upwards, leaving the leaves yellow and falling off. Geranium needs plenty of sunlight during its growing season, so it must be placed in sunny places in winter. Lack of light, stems and leaves lengthy, pedicels soft, inflorescence dysplasia; buds under low light are often poor flowering, withered in advance. Geranium does not like large fertilizers, too much fertilizer will make geranium grow too vigorous and unfavorable flowering.
