Care Guide
Planting
Plant Dense Sedge in a location that gets full sun and has consistently moist to wet soil - this native sedge naturally grows in wet places throughout California, so drainage that keeps soil from drying out is essential. Plant in fall or winter when the Bay Area's rainy season begins, giving roots time to establish before summer. Space plants according to mature width (specific spacing not provided in available data), and choose a spot where standing water or regular moisture won't be a problem for neighboring plants.
After Planting
Water moderately to heavily during the first growing season to establish a strong root system, especially through your first dry summer. Once established, Dense Sedge should need less supplemental water due to its native preference for wet sites, though you'll want to monitor soil moisture during extended dry periods. Deer won't browse this plant, making it a reliable choice for gardens without fencing. The #1 mistake is planting it in dry conditions or allowing soil to dry out during establishment - this sedge isn't forgiving of drought, so err on the side of consistent moisture rather than rationing water.
