How to Propagate Rubber Plant

You will need clean sterilized scissors or a sharp knife, a glass jar, room-temperature water, and optionally rooting hormone.

1. 1 Select a healthy stem tip with at least 2–3 leaves and 4–6 inches of stem. The cutting should come from the current or previous season's growth — greenish stems root much better than old, woody ones.
2. 2 Cut just below a node (the small bump where a leaf attaches) using sterilized tools.
3. 3 The cut end will bleed white latex sap — rinse it under cool running water to stop the flow, then wear gloves for the remainder.
4. 4 Let the cutting sit for 30–60 minutes so the cut end can callus slightly — this helps prevent rot.
5. 5 Remove the bottom 1–2 leaves to expose the node.
6. 6 Place the cutting in a jar of room-temperature water, ensuring the node is submerged but no leaves touch the water.
7. 7 Position in bright indirect light — direct sun will heat the water and promote bacterial growth.
8. 8 Change the water every 5–7 days, rinsing the jar each time.
9. 9 Roots should appear in 3–4 weeks. Wait until roots are 2–3 inches long (typically 6–8 weeks total) before transplanting into well-draining soil.
10. 10 Water the newly potted cutting thoroughly and keep the soil consistently moist for the first 2 weeks.

You will need the same tools plus a small pot with drainage holes, moist well-draining potting mix, rooting hormone (strongly recommended), and a clear plastic bag or propagation dome.

1. 1 Prepare a cutting as described above (cut, rinse sap, callus for 30–60 minutes).
2. 2 Dip the callused cut end in rooting hormone, coating the bottom inch of stem.
3. 3 Plant directly into moist potting mix, burying the node about 1 inch deep.
4. 4 Water lightly to settle the soil.
5. 5 Cover with a clear plastic bag or propagation dome to maintain high humidity — rubber plant cuttings need 60–80% humidity to root successfully.
6. 6 Keep in bright indirect light at warm temperatures (70–80°F). A heat mat underneath the pot significantly improves success rates.
7. 7 Keep the soil consistently moist but not soggy.
8. 8 New growth appearing at 6–8 weeks indicates successful rooting.
9. 9 Gradually remove the humidity cover over 4–5 days.

This method produces the highest success rate because the cutting develops roots while still attached to the parent plant, receiving water and nutrients throughout the process. You will need a clean sharp knife, a toothpick, rooting hormone powder, moist sphagnum moss, plastic wrap, and tape.

1. 1 Select a healthy stem section on the parent plant where you want a new plant to form.
2. 2 Make an upward diagonal cut about halfway through the stem.
3. 3 Insert a toothpick into the cut to keep it from closing.
4. 4 Apply rooting hormone to the cut surface.
5. 5 Wrap a generous handful of moist sphagnum moss around the cut, covering it completely.
6. 6 Cover the moss with plastic wrap, securing both ends tightly with tape.
7. 7 Check the moss every 5–7 days and mist if it feels dry.
8. 8 Roots will develop inside the moss in 6–10 weeks.
9. 9 Once you see a good root network, cut the stem below the rooted section and pot it up.
10. 10 The parent plant will continue growing and often produces new branches below the cut.
