In order to make geranium cuttings survive well, it is necessary to carry out cuttings at the right time. It likes to grow in a warm environment and has the characteristics of heat resistance. Therefore, according to its growth habits, spring and autumn are the most suitable for cutting every year. If it is carried out in summer, it will rot easily.

Growing environment of geranium
Geranium likes warm winter and cool summer. In winter, if the indoor temperature is kept at 10- 15℃ every day and the temperature is above 8℃ at night, the flowers can bloom normally. But the optimum temperature is 15-20℃. Geranium likes dryness and hates dampness, so it is not advisable to water it too much in winter. When the soil is wet, the stems are tender, which is not conducive to the germination and opening of flower branches; If the humidity is too high for a long time, the plants will grow white, the flowering branches will move up and the leaves will turn yellow and fall off.
Geranium needs plenty of sunshine during its growing period, so it must be placed in a sunny place in winter. Insufficient light, long stems and leaves, soft pedicels and poor inflorescence development; Buds in weak light often fail to bloom and wither ahead of time. Geranium doesn't like big chemical fertilizer, too much chemical fertilizer will make geranium grow too vigorously, which is not conducive to flowering.
