How to fertilize Rieger Begonia

1. Fertilization method

1. Seedling stage: This period is when the plant begins to grow, and using only a single fertilizer cannot meet the needs. Therefore, it is necessary to involve multiple nutrients and apply nutritionally balanced compound fertilizers. The fertilization interval is about once a week.

2. Peak growth period: The amount of fertilizer needed during this period changes, and the nitrogen fertilizer content should be reduced. If too much nitrogen fertilizer is used, it will damage the health of the plant. For example, the leaves will curl and affect the ornamental effect of the flowers.

3. Before flowering: The flowering period is a period when fertilizer is particularly needed, because flowering requires more nutrients. If it is not supplemented in time, the number of flowers will decrease, or even no flowers will bloom at all. The fertilizers needed at this time are also phosphorus fertilizer and potassium fertilizer, which are beneficial to the growth of flower buds.

2. Precautions

1. Do not apply fertilizer in summer, winter and flowering period, otherwise side branches will sprout prematurely and the flowers will wither prematurely.

2. When applying fertilizer, pay attention to "apply thin fertilizers frequently", that is, do not apply fertilizers with too high concentrations, otherwise it will cause fertilizer damage and bring a series of harms to the plants, and then apply more fertilizer. However, do not apply fertilizer too often. Once every seven to ten days is enough.

3. When spraying fertilizer on the leaves, pay attention to spraying both sides, do not miss any, and spray evenly.
