Discover a new gardening talent – air-layering woody houseplants

As we start off a new calendar year, how about mastering a new talent? Air-layering is a propagation system I like to do with my woody houseplants that will develop reasonably substantial plants promptly.

The method I will discuss now is most effective utilised on woody dicots (broadleaf vegetation, like a rubber tree or a schefflera). In a upcoming submit I will cover air-layering a woody monocot (grass-like plant, this kind of as a dracaena or dieffenbachia).

The principle

Crops have two types of vascular tissues, phloem and xylem, just like arteries and veins in people. Even though arteries and veins have blood to and from the heart, xylem translocates the water-mineral option from the roots to the rest of the plant, and phloem translocates photosynthates from the leaves to exactly where they are wanted, which includes the roots.

The actively-developing roots develop hormones that motivate stem and leaf production (cytokinins) and the actively-rising tissue at the finishes of the stems makes hormones that inspire root production (auxins). With air-layering we interrupt the stream of the auxins at the position the place we want the roots to expand. As those broken tissues heal the auxins from the tip of the stems stimulate the cells to kind roots.

Elements required

  • Sharp knife
  • Dry cloth
  • 5” x 10” plastic sheet (a 1-gallon storage bag, slice into the suitable size functions well)
  • 1 cup moistened sphagnum peat moss
  • Some sort of tape (electrical operates really effectively)
  • 6” x 12” aluminum foil
  • Some crops might profit from a rooting hormone, but I’ve never employed them
Ron Patterson,


On broadleaf, woody plants the active phloem and xylem kind concentric rings between the bark and the wood. The xylem is the wood-facet ring and the phloem is the bark-side ring. In between is a skinny layer of actively-dividing cells (meristematic tissue), creating much more xylem and phloem as the stem will get more substantial close to. Outdated xylem and phloem grow to be the wood and bark of the stem.

  • Decide on the website in which you want the roots to expand, removing any leaves or stems about 5 inches above and below the air layer web-site.
  • Score and remove about 1 inch of bark all around the stem, so the phloem tissue is girdled, but don’t minimize into the wood as we continue to have to have the xylem tissue to translocate the h2o solution from the roots to the upper aspect of the stem.
  • Rub the exposed stem with a dry fabric to eliminate moist meristematic cells.
  • Employing the plastic and tape, kind a tube around the stem.
  • Close the bottom finish of the tube tightly around the stem underneath the work zone (tape does not have to have to stick to the stem, just the plastic).
  • Things the moistened sphagnum peat moss into the tube so it is located all around the function zone.
  • Shut the major conclude of the tube with tape.
  • Wrap the ball with aluminum foil to block out mild.

Clear away the aluminum foil to verify the root ball for humidity and replenish if required (shouldn’t have to have it). Following about six months you should really see recently formed roots developing in the peat moss.

At this issue you can cautiously eliminate the plastic and peat moss. Reduce the stem down below the root ball and plant in an acceptable pot. Give the plant a week or so out of large light-weight so the roots can get established.

Have fun with your houseplants.
