1. Clove trees are mainly propagated by cutting, mostly in February and March every year.

2. The cuttings should be about 1 cm long with 3-4 buds. The base cutting should be 5- 10 mm below the internode, which is beneficial to the rooting of cuttings.

3. Bundle 50 pruned cuttings and soak the base in 100 mg/9i' nil noise butyric acid solution for 24 hours to promote rooting.

4. Then insert the cuttings with the spacing of about 1 cm into the cuttings bed filled with coarse sand, build an arch with thick steel wires, and then cover it with colorless plastic film to keep the air humidity.

5. The key to improve the survival rate of clove cutting is to keep a high ground temperature. It is best to control the substrate temperature at 25-28℃, and let out fresh air at noon every day, so as to facilitate the rapid rooting of clove cuttings.
