How to Grow

Cultivation

Prefers moist conditions, and often dies back by midsummer. Can thrive in wet, acidic conditions where lawn grasses may struggle, making it a useful, and not unattractive, addition to a species-rich lawn. See field wood-rush in lawns for more information

Propagation

Propagates by seed and by creeping stolons (runners) on the surface of the soil; hand weeding can remove runners in fine lawns
