Care Guide
Planting
Plant willow-leaved dock in full sun to part shade in a location that mimics its natural habitat of sandy or gravelly washes and canyon bottoms. This California native prefers moderate to high water availability, so choose a spot where moisture collects naturally or where you can provide consistent water. Space plants according to their mature size of 1 to 3 feet tall, and plant in fall or winter to take advantage of natural rainfall.
After Planting
Water moderately during the first growing season to establish the plant, then transition to relying on natural moisture once established. Willow-leaved dock is a perennial that will return each year with moderate care demands. This is a relatively low-maintenance plant once settled in, so the main mistake is overwatering during summer months - let it dry out between waterings rather than keeping soil constantly wet, even though it naturally grows in moist areas.
