Stem Cutting Propagation

The most reliable method for climbing aroids

Stem cuttings are the go-to propagation method for most climbing aroids — philodendrons, monsteras, and many others. You take a section of stem that includes at least one node (the point where a leaf attaches) and encourage it to produce roots. Done correctly, the new plant is genetically identical to the parent, preserving any variegation or cultivar characteristics.

Best For

  • Philodendrons (all climbing species)
  • Monstera species
  • Rhaphidophora and Scindapsus
  • Most hemiepiphytic aroids

What You Need

  • Sharp, sterilised scissors or pruning shears (wipe with isopropyl alcohol)
  • Moist sphagnum moss or perlite — or a glass of clean water for water propagation
  • A propagation box or clear plastic bag to maintain humidity
  • Optional: rooting hormone powder or gel
  • A small pot with well-draining substrate for potting up

Step by Step

  1. 1

    Identify a healthy section of stem

    Select a stem with at least one healthy node and ideally one established leaf. Avoid stems showing signs of pest damage, rot, or disease. For variegated plants, choose a section with good variegation expression.

  2. 2

    Make a clean cut

    Cut 1–2 cm below a node using sterilised scissors. A clean cut reduces the risk of infection. You can take a single-node cutting or a multi-node section — both work, though a single node is more efficient if the parent plant is valuable.

  3. 3

    Let the cut callous

    Allow the cut end to dry in open air for 30–60 minutes. This reduces the chance of rot at the cut surface before rooting begins.

  4. 4

    Place in rooting medium

    For sphagnum moss: wrap the node in moist (not wet) sphagnum and seal in a clear bag or propagation box. For water propagation: submerge the node in clean water ensuring the node is covered but the leaf is not. Change water every 3–4 days.

  5. 5

    Maintain warmth and humidity

    Keep the cutting at 20–26°C with high humidity (70%+). Bottom heat from a seedling heat mat significantly accelerates rooting. Place in bright indirect light — never direct sun on an unrooted cutting.

  6. 6

    Wait for roots to establish

    Roots typically emerge in 3–8 weeks depending on species and conditions. Wait until roots are at least 2–3 cm long before potting up. Roots produced in sphagnum or water are often fragile — handle gently when transitioning to substrate.

  7. 7

    Pot up into substrate

    Move the rooted cutting into a well-draining aroid mix. Water lightly and maintain high humidity for the first 2–4 weeks while the plant transitions to substrate feeding.

Tips for Success

  • Bottom heat (22–25°C at the base of the cutting) is the single biggest accelerator of rooting speed
  • Semi-hydro (leca or passive hydroponics) is excellent for rooting cuttings as it eliminates overwatering risk
  • For rare or expensive plants, air layering on the parent before cutting is safer — roots are established before separation
  • Rooting hormone is beneficial but not essential for most aroids

Common Mistakes

  • Taking a cutting with no node — a leaf alone cannot produce new growth
  • Keeping the cutting too wet, which causes the cut end to rot before rooting
  • Placing the cutting in direct sun, which stresses an already vulnerable plant
  • Potting up too early before roots are sufficiently established
