Lilac is mainly distributed in subtropical highland and warm temperate zone, temperate hillside and cold temperate zone. As far as lilac's habit is concerned, it likes light, relatively warm, humid and sunny zone. In addition, lilac is not very resistant to shade, cold and drought. Clove seed planting has higher requirements on temperature and light, lower requirements on soil, and is resistant to barren, but it still likes fertile, loose and well drained soil. Clove seed planting must be careful not to plant in low-lying areas, in order to avoid water.
Sowing propagation is one of the most important propagation methods in lilac planting. Sowing season for spring, autumn, and in the north to spring sowing for the best, mainly in indoor potted or open field sowing.
For indoor potted sowing, it can be carried out in cold room in early spring, and then it can emerge in more than half a month; for open-air sowing, it is necessary to sand the seeds in a lower temperature environment first, so that the emergence time can be reduced. In addition, it can also carry out furrow planting and large-scale planting, as long as attention is paid to the depth of the furrow and between plants. However, no matter indoor or outdoor sowing, transplanting should be carried out after the seedlings grow several leaves, only according to the specific conditions and the growth of clove plants, the number of transplanting and pot dividing is determined. Generally speaking, pot culture for each pot a plant, the open field can be seedlings or transplanting twice.
