3) when cutting cuttings, do not choose too young shoots, those with a high degree of Lignification are easy to take root and sprout.

4) leave the trunk to cut the side branches when pruning, and leave the "root" of at least one bud after pruning to facilitate the next pruning.

5) remove the lower leaves of the cuttings and leave 2 to 3 leaves in the upper part. After the cuttings are repaired, soak them in rooting water.

6) draw a trench with a small shovel on the sand bed, press 5 to 10 cm into the cuttings, cover the soil and press it tightly. The line spacing is 10 to 20 cm.

7) the process of cutting needs to maintain appropriate temperature and humidity, watering should be based on temperature and humidity, and keep the leaves moist all the time. Do not overwater, prolong the rooting time, seedlings can reduce watering appropriately after rooting.

8) it usually takes root about 30 days after cutting, and it can also be bowled at the right time. Bowled nutritious soil can be prepared with sand, soil and peat soil, each accounting for 1/3, to facilitate ventilation, do not fill the bowl too full.

Too long storage time of leaves will lead to the decrease of cutting survival rate. The cutting depth is 2 to 3 cm. After cutting for 20 days, the callus could be produced on the petiole base, the new root could grow from the callus after 30 days, the buds formed on the root primitive after 50 to 60 days, and the buds broke the soil and grew into new plants after 70 to 80 days. The cutter of 1 square meter can cut 1000 to 1500 leaves, and the survival rate can reach more than 95%.
