The primary propagation methods for laser include seed sowing and division. Successful propagation depends on factors such as adequate light, optimal temperature ranges, and well-draining soil. Laser may require specific temperatures for germination or root development. The difficulty can be moderate, contingent on maintaining correct environmental conditions. To propagate by division: 1) Water the plant one day before dividing, 2) Carefully dig up the plant, 3) Separate the roots into smaller sections, 4) Replant the divisions at the same soil depth, and 5) Water thoroughly after replanting.
