1. Do not apply concentrated fertilizer

Viola tricolor is usually applied with thinner fertilizer, which cannot be too thick. If the fertilizer is too thick, its root system is easy to be damaged and easy to burn and rot, so it is generally based on thin fertilizer. When applying fertilizer, because it is thin fertilizer, we should apply it frequently, but we should apply less each time. In this way, it can make its roots grow better

2. Fertilization in different periods

Generally, we should apply a little fertilizer frequently during its growth period, because this time is when it needs a lot of nutrients. We must meet its demand for fertilizer. Generally, the best time for growth is in spring and autumn, but when summer comes, we should apply a small amount of fertilizer. Especially when the temperature is relatively high in summer, it will enter a dormant state. At this time, we must apply less fertilizer because its absorption is limited. When winter comes, the temperature will be relatively low. At this time, we can't apply too much fertilizer. Control the amount of fertilizer, otherwise it will be easy to rot its roots. Therefore, fertilization depends on the time, and the amount of fertilization is different at different times

3. Fertilization techniques

When we fertilize it, we can't finish it directly in order to save trouble. Generally, we first loosen the soil in its basin, so that the word can make its soil soft and have better air permeability, and then apply the fertilizer to be applied, so that it can be better absorbed at this time. In addition, when applying fertilizer, you must not sprinkle fertilizer directly on the roots or leaves, otherwise its roots and leaves will rot, so you must pay attention to this point when applying fertilizer

4. What kind of fertilizer

Generally, nitrogen fertilizer is mainly used during its growth period. When it is about to bloom, it can't use this kind of fertilizer again, and a little phosphorus fertilizer should be added. This can make it bloom more and more beautiful. In addition, when the temperature is relatively low, nitrogen fertilizer can no longer be applied, which will make its roots easy to rot. Therefore, when to apply what fertilizer should be regular
