At present, it is difficult to survive by cutting with ordinary sand bed, but it can be propagated by cutting with floating water, and the survival rate can reach 100%:

① Cut a stout branch (4-5 knots) with the thickness of chopsticks 15-20cm at will.

(2) Cut off the petiole of 1-2 at the lower end of the branch (leave 1 cm branches under the petiole), and insert one end of the cut forest into the plastic foam poked with nails to expose 1-2 leaf nodes, and fix them with broken slag.

③ Float the branches with leaves in a basin of clear water (preferably with proper moss).

(4) Put it in the sun for 20-30 days, and then cut off the leaves under the foam to take root.

⑤ After rooting to a certain length, tear off the foam, take out the saplings and carefully plant them in flowerpots. When they grow to a certain size in the sun, they can be moved to the ground with soil and planted.
