Care Guide
Planting
Plant your small-fruited bulrush in part shade in a location where it can stay consistently wet or even sit in standing water - this is a marsh plant, so wet is what it wants. It's adaptable to sand, loam, or clay soils, so drainage isn't a concern the way it is with other plants; in fact, poor drainage is ideal. Space it with room to reach its full 5–6 feet tall and equally wide at maturity. Spring is the best time to plant, giving it the growing season ahead.
After Planting
Water deeply and consistently through your first summer and into fall; this plant thrives in wet habitats and shouldn't dry out. Once established (by year two), it will handle the Bay Area's dry summers better than you'd expect, though it will perform best if you can keep it moist. In late fall or early winter, the foliage will die back - this is normal for a deciduous plant. The biggest mistake people make is trying to dry it out; resist the urge to let it go dry, especially in its first year.
