Care Guide
Planting
Plant California bulrush in full sun in a location where it can tolerate standing water - this is a marsh plant, so wet is what it wants. It thrives in any saturated or inundated soil and can handle water several feet deep, making it ideal for pond edges, rain gardens, or other water features. Plant in spring for best establishment. Space generously, as this plant spreads aggressively from its rhizomes and will quickly fill available space.
After Planting
Keep the soil consistently moist to wet throughout the growing season; this plant should never dry out. California bulrush is evergreen and cold-hardy to 20°F, so it will persist through Bay Area winters without special care. The main mistake people make is underwatering or planting it in regular garden soil - this plant needs wet conditions to thrive, not typical garden moisture. If it's planted in the right wet spot, it essentially takes care of itself.
