Phosphorus and potassium fertilizer can promote the accumulation of nutrients in flowers, laying a foundation for the second year of growth and flowering. However, it is not possible to apply nitrogen fertilizer in autumn, and nitrogen fertilizer can still be applied to flowers that do not sleep in winter. In particular, foliage plants should still be applied with fertilizers based on nitrogen fertilizer. However, when applying nitrogen fertilizer, attention should be paid to the combination with phosphorus and potassium fertilizer. Reasonable application of phosphorus and potassium fertilizer can improve the cold resistance of flowers. Plants that bloom in winter, such as cineraria, cyclamen, poinsettia, and plum, are vegetative growth seasons in early autumn, and fertilizers based on nitrogen fertilizer should be applied. Most of the late autumn is during the pregnancy buds. When fertilizing such flowers, phosphorus and potassium fertilizers should be the main factor, supplemented by nitrogen fertilizer, and excessive nitrogen fertilizer is not conducive to winter flowering.
