Propagation of Carex crawei can be done through two primary methods: division and seed germination.
Division
Carex crawei can be propagated through division, which involves separating the rhizomes into smaller clumps and replanting them in a new location. This method is best done in the spring, just as new growth begins to emerge.
To divide Carex crawei, carefully dig up the clumps and use a sharp, sterile tool to separate the rhizomes. Each division should have several pieces of rhizome, as well as some roots and foliage. Replant the divisions in a location with well-draining soil and regular moisture.
Seed Germination
Carex crawei can also be propagated through seed germination. To propagate through this method, collect ripe seeds from the plant, which are typically found in late summer or early fall.
Clean the seeds and stratify them for 4-6 weeks at 40º F. After stratification, sow the seeds in a container filled with well-draining soil. Keep the soil consistently moist and at a temperature between 65º-75º F until the seeds germinate, which typically takes 2-6 weeks.
Once the seedlings have reached a size of about 2 inches, transplant them to their permanent location in the garden.
