To propagate star grass, the most common method is by taking stem cuttings from healthy plants, ensuring each cutting has at least a few nodes where new growth can emerge; simply plant these cuttings directly into the desired growing medium, optionally dipping the cut ends in rooting hormone to encourage faster root development. 

Key points about propagating star grass:

Propagation method: Primarily through vegetative propagation using stem cuttings (also called “sprigging”).

Cutting selection: Choose healthy stems with multiple nodes, typically 4-6 inches long.

Planting process: Remove lower leaves from the cutting to prevent rot, then plant the cut end directly into the soil.

Rooting hormone: Applying rooting hormone to the cut end can promote faster root development.
