The branches selected by lilac can affect the survival rate of cuttage, so you can choose the tender branches or the hard branches. In order to ensure the effect of cuttage, it is better to choose the strong plants and cut off the tender branches of the same year from the top.Branches must be healthy and full, no pests and diseases, deal with the branches, cut the branches into about 15cm, the bottom leaves should be removed, do not insert into the soil together, the top can retain a few leaves.
There are few requirements for the selection of substrates, and special cutting soil can be directly purchased, or appropriate substrates can be prepared with vermiculite, perlite, etc., as long as ventilation and drainage can be guaranteed, it will be conducive to rooting.Disinfection should be carried out to prevent the existence of bacteria, eggs and so on.
Spray water into the substrate to keep it wet, use a small wooden branch to poke a few small holes on the substrate, then dip the clove branch in a little rooting powder, and then insert it into the soil, do not need to insert too deep, gently cover and press the substrate with your hand.
After cutting, put it in a cool environment, keep it in a state of astigmatism, do not touch strong light, keep it warm around it, and it will take root after a period of time.
Cuttings can be carried out in July and August of each year, or one month after the flowers fade.
