1、 Breeding environment

1. Soil: loose and breathable soil is best for raising jasmine

2. Watering: watering should be appropriate at ordinary times. If you water too much, the leaves will turn yellow, and poor soil ventilation will lead to rotten roots. If you water too much, put the flowerpot in a cool place and loosen the soil appropriately. In winter, the amount of water should be controlled. The basin soil can be kept slightly wet, and water can be poured once in 5-7 days

3. Fertilization: the flowering period of jasmine is relatively long, so the amount of fertilizer required will increase, especially during the formation of flower buds. However, excessive fertilization will roughly rot the roots. Do not apply fertilizer when the soil is too dry or too wet

4. Light: with sufficient sunlight, Jasmine can grow better. If it is in a shady and cool environment for a long time, it will not bloom due to insufficient light. At this time, it should be placed in a sunny place, apply more phosphorus and potassium fertilizer appropriately, and control the amount of watering, and it will bloom

2、 Breeding method

1. Cutting propagation: select the mother plant of 2-4 years, cut the healthy branches above into about 10cm, remove the lower leaves, leave 2-4 pairs of buds for each branch, insert them into the seedbed, water them, cover them with film, improve the air humidity, and transplant them in about 40 days

2. Pressure propagation: cut the healthy branches up to 15 cm, press them into the soil, and cover them with about 5 cm of soil. After pressing the strip, it should be watered. It will take root in about a month and can be transplanted in about two months

3、 Common diseases and insect pests

1. White silk disease: after discovery, the diseased plants shall be removed. At ordinary times, maintenance shall be strengthened to reduce the source of infection. When the disease is serious, chlorothalonil powder can be sprayed

2. Cinnabar Tetranychus mite: it will cause the leaves to turn yellow or even fall off. When it appears, it can be sprayed with trichloroside EC for control. It will be diluted in 7 days, and it will have obvious effect about 2-3 times
