1、 Fertilization time

1. Spring: spring is the stage when it begins to grow and grow vigorously. During this period, it needs to apply sufficient fertilizer to ensure sufficient nutrients for its growth, which can be applied once every half a month to 20 days

2. Summer: the temperature is very high in this season, and its growth will become slow, even entering the dormancy period. It is necessary to reduce the amount of fertilization or stop fertilization

3. Autumn: autumn is the same as spring. It grows vigorously during this period. It can be applied with nitrogen, phosphorus and potassium compound fertilizer or liquid fertilizer

4. Winter: the temperature is relatively low in winter, and there is no need to apply fertilizer. Just apply a little liquid fertilizer every month to ensure nutrient supply after winter

2、 How to fertilize

Nitrogen phosphorus potassium compound fertilizer is the best when applying fertilizer to asparagus. Of course, liquid fertilizer can also be used, which is easier for plants to absorb. Strengthen the amount of nitrogen fertilizer before flowering, which can promote flower bud differentiation and bloom more brightly. However, we should not apply too much fertilizer during the flowering period. We should do it once in May and June and once in September. If we apply too much fertilizer, it will lead to yellow leaves, overgrowth and so on
