1、 Curing method

1. Soil: there are no strict requirements on the selection of soil. Deep soil is needed. If the soil is loose, fertile and has good drainage, it is better, which is more suitable for the growth of citron

2. Temperature: citron is suitable for high temperature and humid environment, so the best growth temperature is about 25 ℃. It is a kind of plant that is not resistant to cold. It may be frozen to death in case of severe cold. The temperature must be well controlled

3. Shading period: not enough light for growth. I like warm weather. Giving enough sunshine can make it grow faster

4. Water: reduce the amount of water before flower bud formation to promote the growth of branches and shoots to stop gradually. When the flower bud differentiation is completed, the watering amount is slowly restored. When the basin soil is in a relatively dry state, you can sprinkle some water on the leaves in the morning and evening, and point some water to the basin at noon. During flowering and early fruit setting, less water is needed than usual

2、 Breeding skills

1. Pruning: when pruning, you need to cut off extra long and too dense branches, and insert pillars when it bears fruit. During the growth period, it is best to combine binding to shape, and try to retain more branches and leaves

2. Pot change: the pot and soil should be turned over and changed once a year at the seedling stage, and once every 2 years after the age

3、 Diagnosis and treatment problems

1. Insect pests: the insect pests include cotton blowing scale insects. The natural enemy red ladybug can be used to control it. You can also spray rosin mixture. Dilute it 8-10 times in winter and 20 times in summer

2. Falling leaves: the falling leaves of citron are mostly caused by freezing. It is not resistant to cold. A little cold will affect its growth. Therefore, pay attention to protection during maintenance in winter

4、 Other issues

1. Whether it can be cultured indoors: citron can be cultured indoors. If cutting in the house, the room temperature should be kept at 25 ℃ and a certain humidity should be maintained. However, the indoor temperature should not be too high during the fruit viewing period

2. When to bloom: it will bloom successively from the end of August to the beginning of September. Citron can refresh the air. If we create a fresh and humid environment for it, we can prolong the viewing time
