Propagation of Calamagrostis capensis Stapf
Calamagrostis capensis Stapf is a clump-forming grass species that grows well in sunny positions and medium to heavy soils. The plant can be propagated through both sexual and asexual methods.
Sexual propagation
The sexual propagation of Calamagrostis capensis Stapf involves the use of seeds. The plant produces small seed heads that can be harvested and sown in a prepared seedbed. The seed must be covered with a thin layer of soil and kept moist until germination. This method of propagation is easy and reliable but requires a longer time to establish than asexual methods.
Asexual propagation
Calamagrostis capensis Stapf can also be propagated asexually through division. This method involves digging up clumps of the plant and dividing them into smaller sections. Each section should have some roots and shoots. The divided sections can then be planted in prepared soil, watered, and left to establish. Asexual propagation is faster than sexual propagation and is the preferred method for large-scale propagation.
