What is the Best Fertilizer for Lilacs
When planting lilacs, a base fertilizer can be applied. After flowering, apply a phosphorus-potassium fertilizer and nitrogen fertilizer once. Applying nitrogen fertilizer can promote the formation of protein and chlorophyll, making the leaves greener. Phosphorus-potassium fertilizer can promote the differentiation of flower buds and effectively extend the flowering period. After fertilizing, it is appropriate to water moderately to dilute it, which prevents fertilizer damage. Fertilizing should be stopped in winter.
Lilac Fertilizing Time
When planting lilacs, if the soil fertility is insufficient, a small amount of base fertilizer can be mixed in. Also, fertilizing should be done during the growing period and before and after flowering.
Lilacs are mainly top-dressed twice during the flowering period, once before flowering and the second time after flowering, to supplement nitrogen, phosphorus, and potassium nutrients.
What Type of Fertilizer for Lilacs
Lilacs do not require a large amount of fertilizer and should not be over-fertilized to avoid excessive growth of branches, which is not conducive to flowering. It is sufficient to apply a phosphorus-potassium fertilizer and nitrogen fertilizer after flowering. Applying nitrogen fertilizer can promote the formation of protein and chlorophyll, making the leaves greener, while phosphorus-potassium fertilizer can promote the differentiation of flower buds and effectively extend the flowering period.
Lilac Fertilizing Method
1. When planting lilacs, a base fertilizer can be applied, mainly by mixing organic fertilizer with soil evenly. Granular fertilizers applied during the growing period should not be applied directly and need to be diluted with water. The low concentration at this time will not burn the roots.
2. Attention should also be paid to the frequency of fertilizing lilacs. The interval should not be too short, generally once every 15 days. However, it also depends on the plant's growth condition; if the growth is poor, the interval can be shortened.
Precautions for Lilac Fertilizing
After fertilizing lilacs, it is appropriate to water moderately to dilute it, which prevents fertilizer damage. In winter, when the temperature is low and the plant is in a dormant period with slow growth, it does not require fertilizer.
The above experience on the best fertilizer for lilacs in green plants and flowers is shared in the hope that it can be helpful to you in life!
