Care Guide
Planting
Plant your Western Redbud in full sun or part shade in well-drained soil - it's adaptable to most soil types, even sodic soil, so you have flexibility here. The ideal planting time is fall or early spring to establish roots before summer heat. Space it where it has room to reach 10–20 feet tall. In the Bay Area, you're in ideal territory: Western Redbud thrives in northern California's four-season climate and cold winters.
After Planting
Water weekly for the first summer to establish the plant, then taper off - once established, it needs only very low to moderate water and rarely needs more than once-weekly irrigation even in summer. Watch for the showy magenta flowers in spring (March–May), which should arrive without fussing. The biggest mistake is overwatering: Western Redbud is tough and drought-tolerant once established, so resist the urge to baby it. In winter, the plant goes dormant and loses its leaves - this is normal and healthy.
