Tricolor Viola has a great demand for light, so the light must be guaranteed in the maintenance process. If the light is insufficient for a long time and the sunlight is too weak, the growth of the whole plant will become weak and the flowers will not bloom normally. If you want to keep it at home, you can put it on the balcony. Sufficient light can meet the needs of growth. It can be tolerated even under the strong sunshine in summer, but it's best to cover it

2、 Moisture application

The growth is also inseparable from the application of water. It can withstand drought. There are not many requirements for water. Generally, the basin soil is kept dry. In the period of rapid growth of stems and leaves, it is necessary to apply water regularly to keep the basin soil moist, but the water volume should be well controlled to avoid over wetting

3、 Apply fertilizer

During the growth and development period, fertilizer can be applied once a month to ensure sufficient nutritional needs and maintain normal growth. Compound fertilizer should be the main fertilizer to ensure that the proportion of various elements is balanced and can fully meet the needs of growth

4、 Temperature requirements
