How to fertilize lilac, what fertilizer is best

1. Fertilization time

When planting lilacs, if the nutrients in the soil are insufficient, you can mix in some base fertilizer. In addition, during the growth period, especially before and after flowering, special attention should be paid to fertilization.

2. Fertilizer Types

When planting, you can choose some slow-release fertilizer as the base fertilizer, which is very effective. For top dressing during the growth period, you can buy fertilizers specifically for lilacs in stores, such as some granular fertilizers.

3. Fertilization method

1. The operation of applying base fertilizer is relatively simple. Generally speaking, you can just mix it evenly with the soil. Granular fertilizers used during the growth stage cannot be applied directly; they need to be diluted with water before application. After dilution, the concentration will be reduced and it is not easy to burn the roots.

2. Pay special attention to the frequency of fertilization. The interval should not be too short. Generally speaking, once every two weeks is sufficient. However, if you find that the plants are growing poorly, you can shorten the interval.

IV. Precautions

1. After fertilizing, you can add a little water. This way, even if the concentration is high, it can be diluted and will not easily cause fertilizer damage.

2. Furthermore, when the plant is in a dormant period, its growth rate is very slow and it basically has no requirements for fertilizer, so no fertilization is needed.
