1、 What kind of soil

1. Requirements: suitable basin soil is conducive to growth. Although the requirements for soil are not strict, it is best to provide soil suitable for its growth. The soil used should first be loose, which can make the roots breathe normally inside, meet the needs of growth, and have water permeability. Once there is ponding, it can be discharged as soon as possible, and can not accumulate in a large amount in the basin soil. Although lilac can resist barrenness, it also needs to maintain fertility and provide nutrients for growth

2. Soil preparation: the soil used cannot use a single soil, which can not meet all needs. Garden soil, fine sand and rotten leaf soil can be mixed in proportion

3. Disinfection: the prepared soil cannot be used directly. There may be bacteria and insect eggs in it, which need to be disinfected. It can be spread out in the hot sun or mixed with carbendazim solution to disinfect

2、 Other maintenance factors

1. Sunshine: in addition to ensuring proper soil, the potted lilacs also need to ensure sufficient sunshine, which is also very important. When they grow vigorously, they can be raised directly in a place with good light

2. Moisture: water reasonably to maintain the growth needs, but there shall be no ponding

3. Fertilization: apply a certain amount of base fertilizer before putting it into the pot, and apply fertilizer reasonably during growth and maintenance
