1、 Soil

For breeding Viola, loose and breathable soil should be used. If the soil permeability is poor, its roots cannot breathe normally, which is likely to cause rotten roots

2、 Watering

Don't water Viola too often. It can be watered every five days in spring and autumn, and every three days in summer. In winter, the temperature is low, and it can be watered once a week. The amount of watering should not be too large. If there is ponding, it will lead to root rot. in addition, if there is too much rainy season, it should be drained in time to avoid ponding

3、 Temperature

It can grow more healthily at a suitable temperature. In winter, the temperature should not be too low. Generally, the temperature should be controlled above 10 ℃. If the temperature is low, it will be easy to frostbite

4、 Fertilization

Proper fertilization can make it grow stronger. You can apply some bean cake or compound fertilizer when changing pots. During its growth, it is generally applied once every half a month, and appropriate phosphorus fertilizer should be applied before flowering
