How-to Guide
Growing Eastern Redbud (Cercis canadensis)
The short answer
Eastern redbud (Cercis canadensis) is a small, early-spring-flowering tree hardy in USDA zones 4 to 9, growing 20 to 30 feet tall and 25 to 35 feet wide. It grows best in full sun to part shade and evenly moist, well-drained soil, and is adaptable to acidic or alkaline, clay or sandy soils.
Plant it in a permanent, relatively protected spot as early as possible and keep it well watered until established. It does not tolerate heat, drought, or wet soils well, and its brittle branches make a sheltered site important.
Where it grows
- Hardiness: USDA zones 4 to 9
- Light: full sun to part shade; blooms more heavily with more sun
- Soil: pH-adaptable, moderately fertile, moist and well-drained
- Does not tolerate drought, heat stress, or wet soils
Planting and care
- 1Place early — Set plants in their permanent position as soon as possible; redbud resents being moved once established.
- 2Water in — Keep well watered until established.
- 3Mulch — Apply a 3- to 4-inch layer of organic mulch to protect the shallow root system.
- 4Shelter it — Choose a relatively protected area because branches tend to break.
Pruning and lifespan
Redbud can be trained to a single trunk or grown multi-stemmed. It is relatively short-lived, usually 20 to 25 years, so site it where occasional branch loss is acceptable.
