Apple trees are fertilized several times a year

Apple trees need to apply fertilizer four times a year: before flowering, a large amount of nutrients are needed for plant flowering; after flowering, the nutrients consumed by fruit tree flowering are supplemented; during fruit growth, the nutrients needed for fruit growth and development are supplemented; in early autumn, when fruit trees grow slowly, fertilization is needed to accumulate nutrients for plants to prepare for winter.

I. times of fertilization

1. Apply fertilizer before flowering, because plants need nutrients to bloom. If fertilizer is not enough, flowering time will be prolonged.

2. Apply fertilizer after flowering period, and supplement the nutrition consumed by flowering of fruit trees in time.

3. In the fruit growth period, supplement the nutrients needed for fruit growth and development, and make the fruit absorb enough nutrients.

4. In early autumn, when the fruit trees grow slowly, apply fertilizer to accumulate nutrients for the plants to prepare for winter and promote photosynthesis.

2. Precautions

1. When applying fertilizer to fruit trees, we should pay attention to it. Different kinds of fertilizer should be allocated according to the proportion. Do not take it for granted. Fertilization only needs to meet the normal needs of fruit trees, not too much

2. When selecting fertilizer for fruit trees, we should carefully identify the low-cost but not guaranteed quality fertilizer. Poor fertilizer may cause great damage to fruit trees.

3. When applying fertilizer to fruit trees, you can mix some water together, so that the fertilizer will dissolve with the water, which is conducive to soil absorption and volatilization.
