1、 Breeding environment

1. Soil: Gardenia is suitable for growing in acidic soil because it is very beneficial to its growth

2. Watering: it is best to wait until the surface of the basin soil becomes dry before watering, so as not to cause root rot due to excessive ponding. It is best to control the amount of watering in winter. The lower the temperature, the less the amount of watering will be; Water once every 2-3 days in spring and autumn, once every morning and evening in summer and once a week in winter

3. Fertilization: when changing pots, apply organic fertilizer as the base fertilizer, apply organic liquid fertilizer once every 10 days during the growth period, and apply phosphate fertilizer 2-3 times after budding

4. Temperature: the temperature suitable for its growth is 20-28 ℃, and the temperature is very low in winter. It's best to put it in a place with sufficient sunshine and appropriate temperature

2、 Breeding method

1. Cutting propagation: select mature twigs and cut them into 10-15cm long. Cutting in the prepared soil will take root in one month and transplant in about two months

2. Layering propagation: mature branches with a length of about 25-30cm for 1-2 years are put into the soil for about 3cm, and they will take root in a month

3、 Common diseases and insect pests

1. Spot blight: when the disease occurs, the plant will have disease spots. After the disease occurs, the diseased leaves should be removed as soon as possible to prevent the increase of infection sources. At ordinary times, ventilation should be strengthened to isolate the diseased plants so as not to infect other plants. When the disease occurs, Bordeaux liquid can be sprayed once a week

2. Starscream: it will cause the leaves to turn yellow. In order to prevent and control the humidity, clean them with water in time after discovery, or spray them with water soaked in cigarette butts
