1. Basic fertilizer: Violet needs nutrients during its growth, so it is necessary to apply enough basic fertilizer when planting. It is recommended to use livestock manure, phosphorus and potassium fertilizer. The nutrients in the cultivated soil will be improved, and the plants will grow better in the soil with high enough fertility.
2. Fertilizer application in growth period: in its vigorous growth stage, fertilizer should be applied every two weeks, mainly P and K fertilizer. Pay attention that the content of nitrogen fertilizer should not be too much. It can use liquid fertilizer with lower concentration, cake fertilizer, domestic animal fertilizer, or organic fertilizer made by ourselves. In addition, it is better to apply calcium phosphate before it blooms, which is more beneficial to its flowering.
Every time you apply fertilizer, you should pay attention to that the amount of fertilizer should not be too much. If you apply too much fertilizer for a long time, the plant will grow rotten roots in vain and may not blossom. Don't splash the fertilizer on the leaves of plants when applying fertilizer, because the fertilizer will burn the leaves, which will become rotten and reduce the ornamental value. Also, the temperature will accelerate in the hot summer, so it's best not to apply fertilizer at this time
