Propagation through plant cuttings is the most common method used for tropical house plants. The process involves removing current growth from the plant and placing it in an environment that will stimulate new root growth. Take notes during the propagation process to document the propagation steps and rooting times of each plant. This information will be useful for future propagation projects.
Take a plant cutting from current season growth by cutting a 4-to-6-inch section of the plant at a diagonal just below a node on the stem on a middle section of branch. Do not take a cutting from an area at the top of the plant or a branch that has bud growth.
Create a rooting medium by mixing even quantities of sand and peat moss. Lightly moisten the medium with water.
Dip the cut end into rooting hormone. Gently tap the cutting to remove excess hormone.
Fill a 4-inch pot with rooting medium. Insert the cutting into the rooting medium at a depth of one-third to one-half the length of the cutting. Gently firm the soil to hold the cutting in place.
Cover the pot with a clear plastic bag to keep the soil warm and increase the humidity level for the cutting.
Place the cutting in a bright area that has indirect sunlight. Monitor the cutting to make sure the rooting medium does not dry out. Do not overwater the cutting.
