Care Guide
Planting
Plant Brewer's Ragwort in full sun to part shade in a location that matches its native Central Coast habitat. Space plants appropriately to accommodate their mature height of 2 to 4 feet. Since this is a biennial or perennial, plan for it to establish itself over the first year or two before reaching full size.
After Planting
Water regularly during establishment to help your plant develop its fibrous root system, then gradually reduce frequency as it matures and becomes adapted to local conditions. As a native plant from grasslands and woodlands, Brewer's Ragwort is adapted to California's Mediterranean climate, so avoid overwatering once established. The main mistake gardeners make is treating this native like a tropical plant - it prefers drier conditions once it's settled in, especially during summer.
