Mediterranean Bulrush Plant Care

Mediterranean Bulrush (Bolboschoenus glaucus) belongs to the Cyperaceae family within the Bolboschoenus genus. Mediterranean Bulrush is native to most of Africa, Madagascar, southern Europe, the Black and Caspian Sea regions, Western and Central Asia, Mongolia, Pakistan, and India, and it has been introduced to the United States and central Europe. Mediterranean Bulrush is also known as Glaucous Bulrush.

Mediterranean Bulrush displays a grass-like perennial growth habit, reaching up to 4 ft tall with a spread of approximately 2 ft. Mediterranean Bulrush produces small, inconspicuous flowers in clusters.

Leaf size: approximately 12 inches.

Bolboschoenus glaucus requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Mediterranean Bulrush thrives in full sun to part shade.

Bolboschoenus glaucus grows best at temperatures of 50–75°F. Mediterranean Bulrush prefers humidity levels of 60–80%. A pebble tray or humidifier helps maintain adequate moisture around the plant.

Moist, fertile soil with good drainage. Good drainage is essential for Mediterranean Bulrush to prevent waterlogging, which leads to root rot and fungal issues.

Feed Mediterranean Bulrush every month during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.

The PlantoScan app can remind you when to water and when to fertilize each plant.

Divide and repot every 2-3 years. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.

Mediterranean Bulrush can be propagated through division, seeds. Similar propagation techniques also apply to caldwell's club-rush plant care, which shares the same genus.
