Division
Division is a common method of propagating Carex laxiflora Lam. var. gracillima (Boott) Boott ex B.L. Robins. & Fern. It involves separating the parent plant into smaller sections, each with their own roots and shoots. This method is best done during the plant's dormant season, either in early spring or late fall. Care should be taken to ensure that each section has enough roots and foliage to sustain itself after being transplanted.
Seed sowing
Carex laxiflora Lam. var. gracillima (Boott) Boott ex B.L. Robins. & Fern. can also be propagated using seed sowing. Seeds can be collected during the plant’s flowering season, which typically occurs in late spring or early summer. The seeds can be sown directly into the soil in the fall or spring, or they can be started indoors in seed trays and then transplanted outdoors after the last frost.
Cuttings
Cuttings can also be used to propagate Carex laxiflora Lam. var. gracillima (Boott) Boott ex B.L. Robins. & Fern., although this method is less common. Young stems can be cut from the parent plant and placed in water or moist soil until they develop roots. After roots have formed, the cuttings can be transplanted to their final location in the garden.
