How to Propagate Giant bulrush?
The primary methods for propagating giant bulrush are division and seed sowing. Successful propagation requires attention to light (full sun to partial shade), temperature (moderately warm), and a moist, well-draining soil. Special considerations include the plant’s size and the need to handle large, established clumps carefully during division. The difficulty level is moderate, given the plant's size and potential soil requirements. Steps for division include: 1) Water the plant thoroughly a day before dividing. 2) Dig around the clump to be divided, lifting it out gently. 3) Separate clumps into smaller sections, ensuring each has roots attached. 4) Plant sections at the same soil depth as the original and water well.
