The seeds should not be buried too deeply, and seed trays should be kept consistently moist. Germination usually occurs within two to four weeks at a temperate range of 64-72°F.
Vegetative Propagation
Unlike seed propagation, vegetative propagation of Carex stygia Holm, non Fries p.p. reproduces new plants with identical genetic characteristics as the parent plant. This can be done by taking stem cuttings or sections of root. The cuttings or sections of root should be kept moist and planted in a well-draining potting soil or a mixture of peat moss and sand. Within a few weeks, the stem cuttings and root sections should begin to develop roots and new foliage.
Division Propagation
Division propagation of Carex stygia Holm, non Fries p.p. involves splitting the parent plant into sections to create new plants. This method is best performed in early spring when the plant is in its active growing stage. Using a sharp spade or knife, divide the clump into several sections, taking care to ensure each section has healthy roots and new foliage. Plant each section in a well-draining potting soil or a mixture of peat moss and sand and keep the soil consistently moist.
In conclusion, Carex stygia Holm, non Fries p.p. can be successfully propagated using seed germination, vegetative propagation, and division. Knowing the right time to perform each method will ensure a higher success rate in propagating new plants.
