Tulips are usually fertilized in spring and autumn. Spring is the growth period of the plant. Proper fertilization will help it bloom. Planting is required in autumn, so sufficient base fertilizer must be applied. If it is a solid fertilizer, it should generally be applied into the soil and away from the roots to avoid damage. If it is liquid fertilizer, it can be watered directly, while foliar fertilizer needs to be sprayed on the leaves of the plant.

1. Fertilization time

The time for fertilizing tulips is mainly in spring and autumn. When the temperature is high in summer, the plant will enter a dormant state and there is no need to fertilize it at this time. In winter, because the temperature is lower, the plants need to undergo vernalization and it is not suitable to fertilize. Generally, nutrients should be supplemented during the budding and budding stages of plants to promote plant growth and flowering.

2. Fertilizer Selection

Tulip In different periods, the fertilizers chosen are different. After vernalization, the bulbs have just begun to germinate and grow. It is necessary to supplement an appropriate amount of nitrogen fertilizer to promote the development of stems and leaves. Calcium nitrate is generally used and is applied once every other week for a total of three times. After the flower buds form, you can apply phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate, to promote flowering of the plants.

3. Fertilization method

Tulip When planting, you need to apply base fertilizer. The base fertilizer needs to be applied to the bottom of the pot, or it can be mixed with the pot soil. Compound fertilizers applied during the growing season generally require digging a hole on the soil surface first, and then burying the fertilizer, usually away from the roots. After the plants bloom, liquid fertilizer is mostly added, and this fertilizer requires root irrigation. But if it is a foliar fertilizer, it needs to be sprayed on the leaves.

IV. Precautions

Although Tulips prefer fertilizer, but do not apply heavy fertilizer to it, and pay attention to the amount of nitrogen fertilizer. Too thick fertilizer will cause the bulbs to be burned and rot. The pot soil needs to be cleaned in time to wash away the fertilizer and soil, then prune and replant. Too much nitrogen fertilizer will cause the plant to grow leggy, affecting its appearance.
