Breeding methods and precautions of citron

Soil: it is best to use deep, loose and fertile soil with good drainage performance. Temperature: citron is afraid of severe cold. The best temperature for its growth is about 25 ℃. Light: it likes warm growing environment. It should be given enough light and not too shade. Water content: usually, as long as the soil is kept moist, a small amount of water is needed during the flowering and early fruiting period.

I. maintenance method

1. Soil: there is no strict requirement on the selection of soil, and deep soil is needed. If the soil is loose and fertile, the soil with good drainage is better, so it is more suitable for the growth of citron

2. Temperature: citron is suitable for high temperature and humidity environment, so the best growth temperature is about 25 ℃. It is a kind of plant that can't bear cold. It may be frozen to death when encountering severe cold. It must be well controlled above the temperature

3. Light: sufficient light is required during the growth period, and it is not allowed to shade. Like warm weather, give enough sunshine can make it grow faster

4. Water content: reduce the amount of water before flower bud formation, so as to gradually stop the growth of branches and shoots. When the flower bud differentiation is completed, the water quantity will be restored slowly. When the basin soil is in a relatively dry state, some water can be sprinkled on the leaves in the morning and at night, and a little water can be sprinkled to the midpoint of the basin at noon. In the early stage of flowering and fruit setting, watering needs less than usual.

2. Cultivation techniques

1. Pruning: when pruning, extra long and too dense branches need to be cut, and when it results, pillars need to be inserted. Growth period, the best combination of binding to shape, try to retain more branches and leaves.

2. Change basin: turn basin and change soil once a year at seedling stage, and turn basin and change soil once every 2 years after maturity.

3. Problem diagnosis and treatment

1. Insect pest: the insect pest includes cotton blowing scale insects, which can be controlled by the natural enemy red ladybug. Can also spray rosin mixture, dilute 8 - 10 times in winter, 20 times in summer.

2. Leaf dropping: the situation of leaf dropping of citron is mostly caused by freezing. It is not cold resistant, and a little cold will affect its growth. Therefore, in winter maintenance should pay attention to protection.

4. Other issues

1. Indoor culture: citron can be cultured indoors. If it is cut in the house, the room temperature should be kept at 25 ℃ and a certain humidity should be maintained. However, indoor temperature should not be too high during fruit observation.

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