Care Guide
Planting
Plant your Bald-hip Rose in fall or winter (the Bay Area's wet season) in a spot with full sun or part shade - it actually prefers dappled shade over intense afternoon sun. Space it with good air circulation and ensure the soil drains well; while it tolerates clay, it performs best in moist loamy soil with medium drainage. Dig a hole as deep and wide as the root ball, backfill with native soil mixed with compost if your soil is heavy clay, and water in well at planting.
After Planting
Water weekly through your first summer, then taper to once a month or less once established - this is a drought-tolerant plant that will suffer from overwatering. Skip pruning in year one and let it settle in; after the spring blooms fade (March–May), you can remove dead wood or shape it lightly if needed. The biggest mistake Bay Area gardeners make with this plant is overwatering it, especially in the rainy winter months - let the soil dry out between waterings and resist the urge to fuss with it, since it's adapted to our dry summers.
