1、 Flowering period of fragrance:

Jiexiang is a shrub with a height of up to two meters. It usually blooms in April and leaves grow only after flowering. Jiexiang grows in a wide range and spreads all over the country. Jiexiang likes a warm growth environment, especially in the south, but it can also tolerate subzero temperatures. Therefore, under the condition of minus 10 degrees to 20 degrees, Jiexiang can open from March to April of the next year, and if the temperature exceeds minus 20 degrees, Jiexiang must be moved indoors, otherwise it will freeze to death

2、 Regulation of aroma formation:

1. Soil treatment

The soil shall be kept at a certain humidity and shall not be too dry or wet. The soil is neutral and acidic, which is not suitable for the growth of aroma. Because the fragrant root is the living environment that earthworms like, we should pay attention to turning the soil. It is suggested that you provide Jiexiang with an environment with loose soil and good drainage

2. Temperature treatment

In autumn and winter, the fragrance of potted plants should be moved indoors, and the temperature should not be higher than 30 degrees. The optimum temperature is 10 to 25 degrees, not lower than 5 degrees. Different varieties and regions have different low temperature tolerance

3. Fertilization treatment

The most suitable soil environment for aroma formation is fertile soil containing a large amount of humus. It is forbidden to soak the roots in water for aroma formation, and good drainage is required. The grower can fertilize the fragrance every summer. Remember not to use human manure, but professional flower fertilizer. In winter, more flower fertilizer is needed

4. Moisture treatment

Watering and fertilization should be moderate, not too much. If you want to blossom in winter, you need to water frequently in autumn and winter to ensure a slightly wet state. Ponding is easy to rot roots. If it is too dry, it is easy to cause the leaves to fall

5. Precautions

Pruning: in spring, we should prune the branches that are too luxuriant. At the same time, pruning should be "short, tight and healthy". Otherwise, it will affect the flowering in winter
