Propagation of Commelina cordifolia A.Rich.
Commelina cordifolia A.Rich., also known as the heartleaf wandering jew, is a perennial plant that can be propagated through various methods. It is important to note that this plant is not easily propagated through seeds but can be propagated through vegetative means.
Division
One of the most common methods of propagation for Commelina cordifolia A.Rich. is through division. This method involves separating the plant into smaller sections, each with its own roots and stems.

Each section should have at least one healthy stem and a few roots attached and can be replanted in fresh soil.
Cuttings
Commelina cordifolia A.Rich. can also be propagated through stem cuttings. This method involves taking a cutting from an existing plant and planting it in fresh soil. Cuttings should be taken from healthy, mature stems and should be at least a few inches in length. The cuttings can be planted directly in the soil or started in a container with water to encourage root growth before planting.
Layering
Layering is another method of propagation for Commelina cordifolia A.Rich. This method involves burying a stem of the plant in the soil so that a portion is still above ground. The buried portion of the stem will begin to produce roots and once established, can be separated from the parent plant and replanted.
Propagation of Commelina cordifolia A.Rich. can be a relatively simple process that allows gardeners to easily increase their plant collection.
