1、 Breeding environment

1. Soil: it is best to use granular soil for breeding tianjinzhang, or mixed with cinder, peat and hematite soil

2. Moisture: the first watering should be thoroughly watered. Generally, the principle of thoroughly dry watering should be followed. The watering amount can be appropriately adjusted according to the soil drying conditions and weather. For example, the watering amount should be controlled or stopped in the rainy season, and the watering should be appropriately increased in summer for its normal growth

3. Light: some varieties like astigmatism, while others like strong light. Shade measures should be taken in summer and ventilation should be properly increased. Sunshine can be accepted in spring, autumn and winter, but those who have just been put into the pot should grow in the shade

2、 Breeding method

Leaf cutting propagation: cut off the robust plant, complete the petiole and leaves, and apply some fungicides on its incision. Don't let it touch the water, and then put it in a ventilated place to dry. The drying time will be very short, wait patiently, and finally plant it in the soil. After it takes root, it can be maintained normally

3、 Common diseases and insect pests

Tianjinzhang is prone to gray mold and insect pests, especially in summer, so it must be prevented in advance. Carbendazim or chlorothalonil can be sprayed
