Therefore, leaf insertion method can be used to reproduce flower seedlings. Use the shallow basin with a very big mouth surface to make a cutting container, wash clean hind load fry of pure face sand, give water method with basin bottom surface sand is soaked.

Select large and ripe leaves as material. Cut the veins on the back of the leaves with a sterilized blade. The blade is 2cm to 3cm apart and goes deep into the veins. Then place the leaf face up flat on the wet sand, insert the petiole into the wet sand, then press the leaf with a broken glass block, and finally cover the basin with glass, but not tightly. Callus were generated from the vein incision at 20 to 24℃ for 20 days, and young roots and leaves grew after 35 days, at which point the glass ventilation should be removed.

After lobules spread, cut off the main veins between the seedlings and separate the seedlings to the basin. After a month, apply some thin liquid fertilizer and the next year can blossom.
