How to prune eleocharis vivipara

Year-round; thin clumps when they become crowded or plantlets cause tangling. Remove whole overcrowded stems at the base rather than topping them. Snip off dead or yellowing blades individually. Detach daughter plantlets and replant elsewhere if desired.

As needed, roughly every 6–10 weeks. Eleocharis vivipara (umbrella hairgrass) is a taller emergent-style aquatic plant that produces daughter plants at its tips. It needs only occasional trimming to remove dead blades and to control height. Because it spreads via plantlets, thinning overcrowded clumps is more important than routine cutting.
