Water Management for Lilac

When planting lilac in spring, you can loosen the soil after watering three times. After that, you can water it thoroughly once a month. During periods of heavy rainfall, you do not need to water or water it less. Water with frozen water in early December. Freezing water is very important. It not only plays an anti-freeze role, but also helps provide abundant moisture to the lilac, which is beneficial to the growth and germination of trees in the spring of the following year. In March of the second year, you need to water the trees in time to thaw them. This will provide the trees with the water they need to germinate. After that, you can still water them thoroughly once a month. This is the case for the first three years. From the fourth year onwards, except for particularly dry periods, you only need to water the trees with freezing and thawing water every year. When it is particularly dry, water it at the appropriate time.

Fertilizer management for lilac

When planting in spring, sufficient base fertilizer should be applied. In late autumn, use farmyard manure in combination with frozen water. The fertilization method is shallow application, or it can be sprinkled directly on the tree pit. Apply nitrogen fertilizer in the spring of the second year, and add phosphorus and potassium compound fertilizer in July. Apply farmyard manure again in late autumn. Apply fertilizer in this way for the first three years. Starting from the fourth year, apply nitrogen fertilizer once in spring and organic fertilizer once in late autumn.
