What fertilizer can be used to promote flowering when flowers do not bloom

When flowers do not bloom, it may be due to a lack of phosphate fertilizer and potassium fertilizer; generally, an appropriate amount of fertilizer containing phosphorus and potassium can be applied. Flowers generally refer to herbaceous plants with ornamental value; it is a general term for plants that can be enjoyed for their beauty, and their colors are quite diverse, with forms that also differ from one another.
