Care Guide
Planting
Plant your Cascade Barberry in partial shade with fast-draining, acidic soil - think woodland conditions rather than full sun. Space it where it has room to spread, since the foliage can reach up to 6 feet tall even though the stems stay low. Fall or early spring is ideal for planting in the Bay Area. This native shrub is cold-hardy to -15°F, so it's comfortable with our winters.
After Planting
Water moderately through your first summer, but once established (typically by year two), you can back off to watering just once a month or less during summer. The #1 mistake is overwatering - this plant evolved in well-drained forest soils and will suffer in wet conditions. Prune only as needed to shape it or remove dead wood; it naturally stays under 12 inches at the base with spreading foliage above, and doesn't require heavy maintenance.
