Care Guide
Planting
Plant Roundfruit Sedge in a spot with deep shade - this California native thrives under tree canopies and in shaded woodland conditions. It needs fast-draining soil, so amend heavy clay with compost or sand before planting. Space plants about 1 foot apart since they stay compact at 1 foot tall. Plant in fall or early winter to let roots establish before summer.
After Planting
Water regularly through your first summer to help the plant get established, then transition to low water once it's settled in (usually by year 2). This sedge is evergreen and low-maintenance once established - no regular pruning needed. The biggest mistake Bay Area gardeners make is overwatering; remember this plant evolved in well-drained woodland soils, so let the soil dry out between waterings and never leave it soggy.
