The planting bed is filled with half and half sand, covered with plastic film, and the air humidity is kept high. It will take about 40-60 days to take root.
Layering: Choose longer branches, lightly carve the lower part of the node, bury it in a small pot filled with sand and mud, and moisturize it regularly. Roots will begin to form in 20-30 days, and they can be combined with the mother plant after 2 months. Cut off the seedlings and plant them separately.
