How to fertilize African violets

Fertilizer selection for African violets

Since the root system of African violets is shallow and relatively weak, it is not suitable for concentrated fertilizers or organic fertilizers. Adhere to the principle of applying thin fertilizers frequently, in small amounts and multiple times. It is suitable to choose urea, ammonium nitrate, potassium dihydrogen phosphate, etc. for fertilization. They can be used alone or in combination with trace elements. The concentration for spraying on the leaves should not exceed 0.1%, and the concentration for irrigating the substrate should not exceed 0.4%.

How to fertilize African violets

The principle of fertilization is to apply fertilizers with a high nitrogen content when the African violet seedlings are small. As they grow gradually, fertilizers with a balanced nitrogen, phosphorus, and potassium content should be applied. Note that the smaller the seedlings, the lighter the fertilizer should be. During the leaf cutting stage of African violets, vitamin B solution can be used to promote rooting and germination of the plants. Remember not to apply fertilizer within one month after transplanting the seedlings, otherwise it will easily cause the seedlings to rot. Afterwards, use fertilizers with a higher nitrogen content to promote leaf growth and make them shiny. When the seedlings grow up, the fertilizer applied needs to pay attention to a balanced ratio of nitrogen, phosphorus and potassium to promote plant growth. When the African violet plants mature and enter the flowering period, fertilizers with high phosphorus content should be used to promote the differentiation of flower buds and bloom early. Generally, liquid fertilizer should be applied every 10-20 days, and fertilizers with high phosphorus content should be applied before flowering. When entering the flowering period, phosphorus and potassium fertilizers are needed. Do not apply too much nitrogen fertilizer, otherwise the leaves will be lush but no flowers will bloom. You can use a spray bottle to spray the leaves or water the pots to promote absorption.
