1、 Breeding method

1. Temperature: it likes to grow in high temperature and humid environment, so summer is its peak growth season. At ordinary times, the temperature above 25 is the most suitable, and the cold resistance is poor. Therefore, we should pay attention to the low temperature in winter, and the temperature in winter should also be maintained above 16 degrees, otherwise the plant is easy to be frostbitten

2. Soil: it has certain requirements for soil, which should be loose, fertile and breathable. When the proper amount of peat and sapropel is mixed in the cultivation garden, it can meet the basic needs of peat and sapropel

3. Watering: it likes humidity. It must be watered frequently in the growing season to maintain a humid soil environment. However, it should be noted that the humidity should not be too high during flowering, otherwise it is easy to fall flowers

4. Fertilization: the demand for nutrients during growth is also relatively large. Fertilizer should be applied frequently, but only thin fertilizer can be applied. Raw fertilizer or thick fertilizer can not be used, otherwise it is easy to burn and rot roots. Generally, nitrogen, phosphorus and potassium compound fertilizer is applied between April and October. Before application, it is diluted with clean water, and then drenched with fertilizer solution once a week. It is recommended to stop fertilizer in winter to avoid fertilizer damage

2、 Pest control

1. Disease: it is easily infected with stem rot, which is usually caused by long-term ponding. Pay attention to correct watering. When the diseased leaves are found, they should be removed in time to prevent and control the continuous infection. Also spray the medicine. Just use chlorothalonil or carbendazim. Spray it with water once a week or two or three times, and it will be effective

2. Insect pests: common insect pests include powdery bedbugs, leaf blight moths, parasites, red spiders, scale insects, etc. after discovery, they should be sprayed and killed. In addition, the management environment should be improved to avoid re infection
