Updated · Sources · How we source care data
Schoenoplectus acutus, called tule, common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America. The common name derives from the Nāhuatl word tōllin, and it was first recognized by the early Spanish explorers and missionaries in New Spain who saw the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City being used to construct shelters by the indigenous inhabitants.

What Soil Mix Works Best for a Tule?
Moist, fertile soil with good drainage. Good drainage is essential for Tule to prevent waterlogging, which leads to root rot and fungal issues.
How Often Should You Fertilize a Tule?
Feed Tule every 6 months 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.
How Do You Repot a Tule?
Divide and repot every 2-3 years in spring. Choose a pot one size larger than the current container, and ensure it has drainage holes to allow excess water to escape.
How Do You Propagate a Tule?
Tule can be propagated through division, seeds. Similar propagation techniques also apply to american bulrush plant care, which shares the same genus.
