Press it into a pot filled with plain sand 15 cm away from the mother body. The part inserted into the soil must have knots and lightly scratch the lower part of the knots. Cover with soil about 6 to 8 cm thick and keep it moist. Roots will begin in 20 to 30 days. , after 2 months, the seedlings can be separated from the mother and transplanted separately.
