How to Propagate Monstera Split-leaf Philodendrons

Stem Cuttings

• 1

  Clip a 4- to 6-inch section of the vine. Although any section of the vine will root, many prefer to take cuttings from the terminal ends where new growth occurs. Texas A&M University Extension recommends taking cuttings with at least two leaves in the spring to root.

• 2

  Fill plant pots or trays to within 1/2 inch of the rim with a mixture of equal parts peat moss and sand.

• 3

  Remove any leaves on the bottom 2 inches of them stem. Insert the cutting to a depth of 2 inches into the potting media. Place in an area that receives bright, indirect light.

• 4

  Water thoroughly until water runs freely through the bottom of the pot. Keep soil moist until roots form and new growth appears. Test for roots in a week or two by tugging gently on the cutting. If it resists your efforts, roots are established.

Air Layering

• 5

  Make a cut in the stem of the plant with a sharp knife at the point where you desire roots to grow. Texas A&M University Extension notes that the cut should be between 1 1/2 inches to 2 inches long and reach almost to the center of the stem. Insert a toothpick in the cut to hold the wound open.

• 6

  Soak a handful of sphagnum moss in water for two to three hours, prior to making the cut for air layering. Squeeze the moss in your hands an allow excess water to drain.

• 7

  Wrap the moss around the cut in the stem, so that it encloses the stem. Secure the ball of moss to the main stem with garden twine.

• 8

  Cover the moss with polyethylene film and secure both ends to the stem with tape to completely seal the moss.

• 9

  Watch for roots to form and emerge through the moss. When the bag is filled with roots, cut the stem and pot the new plant is soil.
