Air Layering: The Only Reliable Way to Propagate Large Rubber Trees

Your 8-9 foot rubber tree (Ficus elastica) has grown horizontal from heavy side branches. You want it vertical and to root the side branches. Air layering is the only method with high success for woody Ficus stems.

Why Cuttings Fail

Rubber tree stems are too woody and large for standard cuttings. They rot before rooting.

Air Layering: Roots Before You Cut

1. Select a healthy section on the branch you want to remove
2. Make a shallow upward cut ⅓ through stem
3. Insert toothpick to keep wound open
4. Wrap with damp sphagnum moss
5. Seal with plastic wrap (both ends tight)
6. Wrap with foil to block light
7. Wait 3-6 weeks for roots to fill moss
8. Cut below rooted zone, pot up

For Your Tree

Air layer each side branch you want to propagate. Once rooted and potted, you can stake the main trunk vertical. The new plants will be clones—same beautiful foliage.

Spring/summer is ideal timing. Your 15-year-old tree deserves this rejuvenation!
