How to fertilize lilac

First of all, the soil for growing lilacs must be fertile, loose, and well-drained, with sufficient nutrients to meet the growth needs of lilacs. During the growth process of lilac, it is necessary to apply fertilizer in time. Lilac does not like large amounts of fertilizer. Excessive fertilization will cause the branches and leaves to grow too long, and the flower buds will be difficult to form due to lack of nutrients, resulting in reduced flowering, so fertilization is very important.

Lilac needs to be supplemented with nutrients in time after flowering to promote the recovery of the plant, and appropriately supplement nitrogen, phosphorus and potassium. Usually, each plant should have about 75g of phosphorus and potassium fertilizer and 25g of nitrogen fertilizer. Be careful not to use too much nitrogen fertilizer, otherwise it will affect flowering in the second year.

In addition, generally every year or every other year, before winter, you should apply well-rotted compost to replenish nutrients in the soil and allow the lilac to safely overwinter.

What fertilizer to use for lilac

As long as it is a flowering plant, the nitrogen fertilizer content cannot be too much. The same goes for lilac. When choosing fertilizer, pay attention to the combination of phosphorus and potassium fertilizers. If you are raising lilac at home for the first time, you can choose special fertilizer for flowering plants. The various elements are reasonably proportioned, which can not only ensure the air permeability of the soil, but also have a long fertilizer effect and can improve the soil.

Fertilization tips for lilac

Generally, fertilizers on the market are granular. You can choose to dig a pit next to the plant and bury it shallowly, avoiding the rhizomes. This method can extend the fertilization cycle and allow the fertilizer to take effect slowly.

Alternatively, you can dilute granular fertilizer with water and then water the plants. This method allows the fertilizer to come into direct contact with the plants, which can quickly increase soil fertility, but improper concentration control can easily burn the roots.
