The best method to propagate a pothos vine is by tip or stem cuttings. Stem cuttings are taken at different stages of growth and may consist of a plant's growing tip (terminal section) or stem sections below the terminal section; they are referred to as tip cuttings or stem cuttings, respectively.
Techniques
• Remove stem cuttings using a clean, sharp knife or pruner. Cuttings 4 to 6 inches long are appropriate for most plants.
• Remove leaves from the bottom 1 to 2 inches of the cuttings.
• Dust cuttings with rooting hormone, and stick them upright in a propagation medium.
• To stick a cutting, create a hole in the media using a pencil as a dibble. Gently insert the cutting without rubbing off most of the rooting powder.
• Insert them just deep enough into the propagation medium to hold them upright (usually 1 to 2 inches). Insert at least one node (growth point) into the medium. Roots develop faster at nodal areas with active meristematic cells.
• After you insert cuttings, water them to firm the medium around them.
• Stem cuttings have rooted when they cannot be easily dislodged from the rooting medium. The rooting period varies from 2 to 16 weeks, depending on plant species and environment. Once well rooted, cuttings can be potted into containers and grown to larger size.
