1、 Breeding method

1. Soil: evergreen doesn't have high requirements for soil. Just pay attention to drainage, and don't use clay and alkaline soil. Rotten leaf soil mixed with sandy soil can be used as matrix, and broken tiles can be padded at the bottom to increase its drainage capacity

2. Light: Evergreen is suitable for growing in semi shade environment and is afraid of strong direct light. If it is in summer, it needs to be shaded to avoid water loss caused by exposure. It can also be placed in the semi shade to receive a certain amount of scattered light. However, in order to promote flowering, appropriate light is also needed

3. Watering: evergreen has high requirements for air humidity, and the basin soil should not be too wet. Water less. Generally, water a little when the surface soil is dry to keep it slightly moist. You can sprinkle water around you. In summer, you can sprinkle water every morning and evening to keep the environment moist

4. Sufficient fertilizer is needed during the growth period of ten thousand years. Fertilizer should be applied every 20 days. The fertilizer can be rotten liquid fertilizer, which is better combined with Gaoxin lipid membrane. Fertilizer should be applied frequently in early summer, once every 10 days. Before flowering, a little potassium dihydrogen phosphate can be added to promote flower bud differentiation

2、 Reproductive skills

1. Ramet: the ramet of evergreen is usually carried out in spring and can be combined with pot change. After taking out the plant, cut off the rhizome at the base and apply plant ash for disinfection. Wait for it to dry and replant it. Pour a little water

2. Cutting: cutting can be carried out in spring and summer. Cut a tender stem of about 12 cm as a spike, and keep the top leaves. Insert it into the sand bed, control the temperature between 25-30 ℃, and take root in about a month

3. Sowing: sowing is generally carried out from March to April. Plant the seeds in loose and fertile soil, water and put them in the shade. Keep the environment moist and sprout in 25 days

3、 Pest control

1. Diseases: common diseases include leaf spot and anthrax. First remove the diseased branches and leaves and destroy them in a centralized manner. Then spray Bordeaux liquid and put it in a ventilated place to recover

2. Pests: brown soft scale is the main pest. If the quantity is small, it can be scraped off with bamboo chips, and then Omethoate can be used to kill the larvae
