Where should I cut a pothos vine for propagation?

Prof. Martin Thorne, Ph.D.Learning to propagate pothos begins with very careful pruning. You want to make your cut right below a leaf node since this knobby growth point contains root cells that are dormant, but ready to go. I always use my very sharp and sterilized scissors, often old nail clippers for the more delicate stems. It is best to use proper technique so that you are not crushing the stem because crushed plant cells are great places for bacterial rot.
Sterilization Essentials
- Disinfect tools with 70% alcohol before each use
- Boil glass jars for 10 minutes to kill pathogens
- Replace water every 5 days to prevent biofilm
Node Optimization
- Select stems with 3-4 aerial roots for faster growth
- Remove leaves 1 inch above cut to focus energy
- Angle cuts to increase surface area for rooting
Water propagating displays clear progress, although there is a concern for potential sliminess if left too long. Most of my houseplants live in small jars and vases that you can find on my kitchen windowsill, and every time I toss in a new root system it gives my spouse and me something to talk about for a few weeks. For those who like soil propagation, try putting perlite in your potting mix so that the roots can breathe. Or, for those varieties that require higher humidity, use sphagnum moss.
Investigate yellowing leaves by checking for drainage issues. Cuttings that were grown in overly wet soil need gritty pore space amendments like orchid bark. If your cuttings' roots are rotten in the water, just trim the rotten areas off and restart in drained boiled-cooled water. One of my most horrible failures turns out to be one of the best lessons. The lesson is, that patient over panic will always be better in plant rehabilitation.
Week 1-2
- Change water medium every 48 hours
- Mist soil cuttings lightly each morning
- Rotate jars to ensure even light exposure
Week 3-4
- Introduce diluted seaweed extract for root stimulation
- Gradually reduce humidity dome usage
- Check for resistance by gently tugging stems
