What fertilizer is best for lilac?

Lilac fertilization time

When planting lilac, if the soil fertility is insufficient, you can mix in some base fertilizer. Secondly, fertilization should be carried out during the growth period and before and after flowering.

Lilac is mainly fertilized twice during the flowering period. The first time is before flowering, and the second time is after the flowering period to supplement nitrogen, phosphorus and potassium nutrients.

What fertilizer to use for lilac

Lilac does not require much fertilizer, so there is no need to apply too much fertilizer to it, so as to avoid the branches growing too long, which is not conducive to flowering. You can apply phosphorus, potassium and nitrogen fertilizers once after flowering. The application of nitrogen fertilizer can promote the formation of protein and chlorophyll, making the color of the leaves greener. Phosphorus and potassium fertilizers can promote the differentiation of flower buds and effectively prolong the flowering period.

Lilac Fertilization Method

1. When planting lilac, base fertilizer can be applied, which is mainly to mix organic fertilizer evenly with the soil. The granular fertilizer applied during the growth period cannot be applied directly, but needs to be diluted with water. The concentration at this time is lower and will not burn the roots.

2. Lilac also needs to pay attention to the frequency of fertilizing. The interval cannot be too short. Generally, it is sufficient to apply fertilizer once every 15 days. However, it also needs to be based on its growth. If it grows poorly, the interval can be shortened.

Notes on fertilizing lilac

After fertilizing lilac, you can water it appropriately to dilute it, which will not easily cause fertilizer damage. In winter, when the temperature is lower and it is in a dormant period, its growth rate is very slow and it has no demand for fertilizer, so no fertilization is needed.
