1、 Breeding conditions

1. Soil: it likes sandy loam with air permeability, softness and water storage

2. Light: it likes a mild and humid growth environment and does not like light. It should be properly shaded in summer. The comfortable growth temperature is 18 ℃ - 24 ℃, 18 ℃ - 30 ℃ from February to October, and 13 ℃ - 16 ℃ from October to February of the next year

3. Watering: it is suggested that the water should be permeated once at the beginning of planting, and the water supply should be controlled during daily maintenance. It is not good to give too much water if the root system is rotten

4. Fertilization: the growth period is about 7-10 days, and thin liquid fertilizer or compound fertilizer is applied once. Don't give too much fertilizer, otherwise the leaves will grow well but don't bloom

2、 Breeding method

1. Cutting: select the strong branches from the mother plant, disinfect the wound, place them in the shade and dry them. After treatment, cut the leaves into the loam and water them properly until they take root

2. Sowing: it is generally carried out from March to April. After planting, it shall be placed in a cool and ventilated place, and the temperature shall be kept at about 24 ℃. It can germinate in about 10 days

3、 Pest prevention

1. Botrytis cinerea: in the early stage of the disease, spots in the shape of water stains appear on the leaves. When they are serious, they will turn black brown and rot. At this time, sick leaves should be destroyed to prevent infection, and indoor ventilation should be strengthened

2. Leaf beetle: generally, leaf beetles often appear in tropical areas. They will bite leaves and destroy the effect of leaves. At this time, pesticides can be captured or sprayed manually
