How to propagate Philodendron billietiae

How to propagate by stem cuttings

Stem cuttings are a reliable way to propagate Philodendron billietiae. Each cutting contains a node (the small bump or joint where a leaf attaches), and that node is where new roots will grow.

1. 01

   Choose a healthy stem with at least one node and one or two leaves. In spring or early summer the plant is growing actively, so cuttings root fastest.

2. 02

   Cut just below a node using clean, sharp scissors or a knife. A cutting of 10–15 cm (4⁠–⁠6 in) with one or two leaves is ideal.

3. 03

   Remove any leaves from the bottom 5 cm (2 in) so they don’t rot in water or soil.

4. 04

   Choose one

   Water method Place the cut end in a glass of room-temperature water, keeping the leaves out of the water. Change the water every three days. Move to soil once roots are 2–3 cm (0.8⁠–⁠1.2 in) long.

   Soil method Dip the cut end in rooting powder (optional), then push it 3–4 cm (1.2⁠–⁠1.6 in) into damp potting mix. Cover loosely with a clear bag to keep humidity high.

5. 05

   Keep the cutting in bright, indirect light and warmth (above 18 °C / 64 °F). Avoid direct sun, which wilts the cutting before roots form.

6. 06

   Usually roots in 3–5 weeks. New leaves alone do not prove that roots have formed. Check for visible roots or gentle resistance in the mix without pulling the cutting out. Once rooted, gradually increase ventilation and remove any cover over about two weeks before moving to normal care.
