Polynesian Ivy Vine (Pellionia repens) can be propagated at the beginning of the growing season from stem-tip cuttings or by plant division.
Take stem-tip cuttings of about 4-5 in. length from a healthy Polynesian Ivy Vine. Ensure each cutting has at least one set of leaves and 2-3 leaf nodes. Strip off the lower leaves.
The stem cuttings root easily and there is no need for a rooting hormone.
Insert the cuttings in moist, free-draining soil. Ensure that the rooting container has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Place the set up in warm, brightly-lit place away from direct sunlight. Maintain the soil moist until new growth emerges and substantial growth is observed.
Transfer the new Pellionia repens Vines to individual pots and begin routine care. For a fuller plant, transfer several cuttings into one pot.

Select a 6 or 8 in. pot and ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting.
Fill the pot with free-draining soil and make a hole in the center of the pot. Ensure that the hole is slightly wider than the root base of the section.
Place the section in the previously made hole and lightly firm the soil around the base while taking care not to bury it too deep; maintain the section at the same soil level as it was in the previous pot.
Water the soil thoroughly and place the set up in a well-lit, warm place away from direct sunlight.
Allow the new Pellionia repens to be well established after which you can begin routine care.
