Bulrush (Bolboschoenus) grows in the shallow water around ponds and in wet, waterlogged marshy areas. Bulrush varieties grow throughout the world, providing habitat for a variety of aquatic species. These members of the Cyperaceae, or sedge, family are tall, commonly reaching 10 feet in height. This grasslike plant has a long history: Ancient Egyptians used the bulrush variety Cyperus papyrus to make papyrus. Plant bulrush in a garden pond or wetland area, but be aware --- this plant can take over quickly.
Plant bulrushes up to 20 inches deep in the shallow water around the edge of a pond or in wet marshlands. Use a shovel to dig a hole in the soil large enough to accommodate the root mass.
Remove the bulrush from the nursery pot or plastic wrapping and place it in the hole under the water or in the marshy area. Move soil around the roots to secure the bulrush in place.
Cut back the stalks in the winter for a tidier appearance. Cut the stalks 10 inches above the water line, or 10 inches above the soil line when planted in marshland.
Divide bulrush anytime between spring and late summer. Dig up a section of the root mass. Bulrushes have a fleshy, bulbous root system called a rhizome. Divide the rhizomes into sections containing three to five stalks each.
Replant the rhizomes in a new area or pot them up to give away to other aquatic plant enthusiasts.
