No need to buy flower fertilizer anymore, this stuff works even better than flower fertilizer

Clivia, add some charcoal to the clivia's flower pot. Charcoal can improve the air permeability and drainage of the potting soil. Charcoal is rich in phosphorus and potassium elements, which greatly helps the growth and flowering of clivia. High phosphorus and potassium content in the soil can also treat clivia's leaf spot disease and so on
In summer, when the weather is hot, stop fertilizing. Apply a dilute soybean cake liquid fertilizer once every half month. Wait until the soil is dry before fertilizing, so it is absorbed quickly. Do not apply fertilizer too concentrated, otherwise the roots are prone to rot. The fertilizer water must not touch the leaves. Clivia must have its soil and pot changed every year after it blooms in spring. It is best to choose a deep clay pot, not a porcelain pot, which has poor air permeability
Make sure the clivia gets a certain amount of light. In winter, the clivia can be kept in a bright place for a long time, but in the hot summer, pay attention to shading. It can get light in the morning and evening. When repotting the clivia, trim the rotten roots, then spray wood ash on the wounds. This can control root rot and also promote new root growth, helping the clivia's growth
