Care Guide
Planting
Plant California stinkweed in full sun with fast-draining soil - it thrives in the gravelly, well-drained conditions of its native open flats and slopes. This annual germinates in cool weather, so plant in fall or early spring to establish before summer heat. Space plants 6-12 inches apart depending on your desired density, as this species spreads naturally.
After Planting
Water regularly during establishment and through the growing season, tapering off as the plant matures since it evolved in seasonally wet areas. As an annual, expect California stinkweed to complete its life cycle in one season, flower, set seed, and die back - no pruning needed. The biggest mistake is overwatering or planting in slow-draining soil, which will rot the roots faster than the plant can handle.
