Bulrushes are perennial grass-like plants and can grow to 10 feet tall in shallow water or in moist soils. Giant bulrush can also grow to 10 feet. Bulrush stems are dark green with a hard, triangular stem and no obvious leaves (sheaths at the base of the stems). Seed clusters usually occur just below the tip of the stem.
Bulrush can be cut down or the rhizomes (roots) can be dug up. It will be difficult to control this way because it will regrow from seeds and remaining rhizomes.
Chemical Application Best Practices
Anytime you use chemicals treat weeds or algae, please keep in mind the following:
- Treat your pond in sections. Treat only half the pond's surface at a time, if the weather is hot, only treat 1/4-1/3 of your pond. Wait 10-14 days between treatments.
- Once the weeds have browned, use a rake to remove as much dead material as possible. This prevents an accumulation of dead plant material and muck.
- Treat your pond with the proactive approach to pond management. Use PondClear™, MuckAway™ and Pond Dye to keep your pond looking great.
