Lilac can be propagated by seeds, which is one of the methods of propagation, through which new plants can be cultivated, but we should pay attention to the way of sowing.
1. Selection of seeds: Seeds are one of the important factors for propagation. Appropriate seeds are conducive to germination. You can select full and good quality seeds from them. The storage time should not be too long, otherwise the germination rate will be affected.
2. Seed treatment: Seeds need to be treated before planting. Soak the seeds in hot water for a period of time, then take them out and mix them with wet sand. Keep them moist and put them in a sunny place. They will germinate in about a week.
3. Preparation of soil: The preparation of soil is also very critical. It is necessary to prepare a suitable matrix, which must be loose, soft and breathable. A certain amount of base fertilizer should be applied. It is necessary to pay attention to disinfection when preparing the soil.
4. Sowing: The germinated seeds are evenly sowed in the soil, and then covered with soil. It is not necessary to cover too much soil, as long as the seeds can be covered.After sowing, water twice to ensure sufficient sunshine.
The time of sowing should be chosen well, preferably in spring or autumn, and the temperature can be maintained at about 20 degrees Celsius, especially in spring sowing in the north.
