1、 How to supply water

1. Frequency: lilacs like to be wet, but they are more drought resistant. They don't need too much watering. The management is relatively extensive. Generally, they supply water after finding that the soil is dry. Under normal circumstances, in the spring and autumn season, it can be watered every 7-10 days to meet the demand for water. In summer, the light is relatively strong and the temperature is high. At this time, the demand for water is large. It can be watered every 1-2 days. It can not keep the basin soil in a dry state for a long time, otherwise it will cause the leaves to turn yellow, and the demand for water in winter will be greatly reduced. It can be watered once every two weeks

2. Watering thoroughly: when watering, you must pay attention to watering thoroughly. If the watering is insufficient, the root under it will not be able to absorb water, but the top will be very wet. If it goes on for a long time, it will not be good for the growth of plants, and it will still be short of water and dry

3. Water spraying: in addition to normal root watering, it can also cooperate with water spraying when the air is relatively dry

2、 What about root ponding

Lilac can't stand ponding. If there is ponding at the root once watering too much, you need to stop watering immediately, and then loosen it carefully to promote the discharge of water. Put lilac in a well ventilated place to circulate air
