1、 Fertilization time

Tulip fertilization time is mainly in spring and autumn. When the temperature is high in summer, the plant will enter a dormant state. At this time, there is no need to fertilize it. In winter, because the temperature is low, the plants need to undergo vernalization, and fertilization is not suitable. Generally, nutrients should be supplemented during plant germination and budding to promote plant growth and flowering

2、 Fertilizer selection

Tulips choose different fertilizers in different periods. After vernalization, the seed ball just begins to sprout and grow. It is necessary to supplement an appropriate amount of nitrogen fertilizer to promote the development of stems and leaves. Generally, calcium nitrate is applied once every other week for a total of three times. After flower buds are formed, phosphorus and potassium fertilizer, such as potassium dihydrogen phosphate, can be applied to promote plant flowering

3、 Fertilization method

When tulips are planted, base fertilizer should be applied to the bottom of the basin or mixed with the basin soil. The compound fertilizer applied in the growth period generally needs to dig pits on the soil surface first, and then bury the fertilizer, which is generally far away from the root. Most of the plants are supplemented with liquid fertilizer after flowering, which needs to be irrigated with roots. But if it is foliar fertilizer, it needs to be sprayed on the leaves

4、 Precautions

Although tulips prefer fertilizer, do not apply concentrated fertilizer to them, and pay attention to the amount of nitrogen fertilizer. If the fertilizer is too thick, the bulb will be burned and rotten. It is necessary to wash the basin soil in time, wash off the fertilizer and soil, and then trim and replant. Too much nitrogen fertilizer will lead to plant overgrowth, which will affect its beauty
