Propagation of Carex oklahomensis Mackenzie
Carex oklahomensis Mackenzie, also known as Oklahoma sedge, is a popular ornamental grass used in landscaping. This grass can be propagated through various methods, including:
Division
Division is the easiest and most common method of propagating Carex oklahomensis. This process involves dividing clumps of the grass into smaller sections and planting them individually. It is best to do this in the spring when the grass starts to grow. Carefully dig up the clumps and use a sharp knife or spade to divide them into smaller sections. Each section should have roots and a few stems. Replant the sections immediately and water thoroughly.
Seed
Carex oklahomensis can also be propagated by sowing seeds. Collect the seeds in the fall when they are fully mature. Sow the seeds in a prepared seedbed in the fall or early spring. Cover the seeds with a thin layer of soil and water them lightly. Keep the seedbed moist until the seeds germinate. Once the plants are large enough, they can be transplanted into their permanent location.
Cuttings
Propagation by cuttings is possible but it requires a bit more skill. Cuttings should be taken in the spring. Take 3 to 4 inch cuttings from the tips of the grass blades. Remove the lower leaves and plant the cuttings in moist potting soil. Keep the soil moist and the cuttings in a shaded area. Once the cuttings root, they can be transplanted into the ground.
