The adaptability of keel flower is relatively strong, and the requirements for soil are not strict. Even if ordinary soil is used, it can survive. It is best to use loose and nutrient permeable soil, which is more conducive to its growth. In addition, when cultivating keel flowers, loosen the soil properly, or the cultivated soil will become hardened, which will hinder root respiration and affect its growth.
When cultivating keel flower, we can use compound fertilizer, rotten manure, or bean cake fertilizer. The concentration of soil should not be too high, otherwise the phenomenon of fertilizer damage will occur, and the phenomenon of rotten root will also be caused. Fertilization frequency should also pay attention to good, usually every half a month or 20 days to apply fertilizer to it, fertilization is too diligent, the plant will absorb.
1. When applying fertilizer, it is necessary to apply fertilizer in spring and autumn and winter. In summer, it is not necessary to apply fertilizer. In addition, fertilizer should be applied near the root of the plant, not at the root.
2. After flowering, you can give the plant some potassium dihydrogen phosphate solution in spring, which will help the flower bloom more vigorously.
