1. Temperature: the temperature suitable for plant development is between 15 ° C and 25 ° C, and the temperature for overwintering in winter should be more than 10 ° C. Therefore, the plants planted in the North should be moved indoors for maintenance in winter..
2. Watering: the water consumption during the growth period is relatively large, and the soil needs to be kept moist for a long time. Generally, watering once every two days, and properly control watering when not growing. Generally, watering twice or three times a week. After the temperature is below - 10 ℃, cut off the water to avoid the frostbite caused by the low water temperature.
3. Fertilization: it likes fertilizer. When it blooms, the flowers bloom continuously, and the demand for nutrients is even greater. Relying on the nutrients in the soil alone is far from enough, and it needs artificial fertilization to meet its demand. Generally, in the growth period, fertilization is required once every half a month, and the fertilization is mainly based on the compound fertilizer with moderate fertilizer effect and convenient absorption. You can also use self-made retting. Retting is made by putting the rotten skin of fruits and vegetables together with the internal organs of animals, and then burying them in the soil, so that they can fully ferment. After fermentation, retting is done, which can be directly used by plants.
4. Light: it is not resistant to strong light, too strong light will cause the curl and death of the plant's branches and leaves, so it is necessary to shade, especially in summer, in the morning and in the evening, it can be normally illuminated, in the noon, it is necessary to shade, and the daily illumination time is guaranteed to be six hours.
1. Reproduction: it can be propagated by sowing. The sowing method is used in breeding. Under the temperature of 15 ℃ to 25 ℃, the seeds can emerge in half a month. When they grow two real leaves, it's time to transplant them
2. Pruning: generally, the way of pruning plants is to remove the center. Picking can promote the growth of lateral buds, avoid the advantage of the top, and also make the nutrient distribution more uniform. After picking, the incision can't meet water temporarily. After the incision is dry, it can be watered normally.
1. Yellowing of branches and leaves: most of the yellowing of branches and leaves in Campanula is caused by too strong light. It is necessary to control the light properly and ensure that the plants will not receive strong light after that. When the light is mainly scattered, this problem will be solved..
2. Rotten root: the problem of rotten root may be caused by excessive watering, resulting in ponding of basin soil and impermeability of soil. It needs to be dug out of the soil, and then the rotten roots will be cut off, and then replanted into the soil with good permeability.
1. Toxicity: non toxic.
2. Edible: it can't be eaten directly, but it can be used as medicine.
