Alkali Bulrush

Bolboschoenus maritimus subsp. paludosus

Alkali Bulrush (Bolboschoenus maritimus subsp. paludosus) is a plant species native to wetland margins and saline areas. It has deep-rooted, slender stems and can reach heights of up to 6 feet. The grassy foliage is dark green and feathery, with a brownish seed head in spring and summer. The plant is very tolerant of high salinity levels and is often seen around shorelines, ponds and marshes. It is a common sight along saltwater coasts and is great for erosion control as its roots hold soil firmly in place. Alkali Bulrush provides valuable habitat for fish, waterfowl, and amphibians.

watering

Alkali Bulrush should be watered deeply twice a week in warmer months, and only once a week in cooler months. Generally, about 2-4 gallons of water per application should be used when providing water to the Alkali Bulrush. When the soil feels dry to the touch, it is time to water again. It is important to remember to not over-water, as this can cause root rot.

sunlight

Alkali Bulrush typically enjoys ample amounts of direct sunlight and thrives in full or partial sun. It should get at least 6 hours of direct sunlight per day and if possible, up to 10 hours of daily sunlight is ideal. To ensure this species thrives, it is important to provide appropriate light throughout the entire year. During the summer, Alkali Bulrush should be exposed to a full 10 hours of sunlight and during the winter, that should be reduced to 6-8 hours of sunlight.

pruning

Alkali Bulrush should be pruned very lightly in early spring and then again in the late summer. Pruning in this way keeps it from becoming too dense, releasing some of its energy for blooming. It is best to clip only off the top 6-10 inches of the plants, since going too deep when pruning can damage the plant's root system. Remove any dead or unattractive foliage, as well as any branches that are growing in a less than desirable direction. Monitor the plant over the season and periodically prune off any dead or excess foliage as needed.
