Transplant Establishment
4-8 weeksYoung plant with initial foliage; leaves may be bright red-orange as new growth emerges
Water regularly to establish deep root system. Avoid transplant shock by planting in spring or fall. Mulch around base to retain moisture and regulate soil temperature.
Vegetative Growth
Spring through early summer (8-12 weeks)Plant develops branching structure and fuller form; foliage transitions through spring colors (red-orange to bronze-green)
Light pruning to shape and remove dead wood. Fertilize monthly with balanced slow-release fertilizer. Monitor for pests and diseases.
Summer Maturation
June-August (8-10 weeks)Foliage settles to bronze-green or muted red tones; plant reaches structural fullness
Maintain consistent watering during heat. Deadhead spent flowers if desired. Reduce fertilizing. Watch for spider mites in dry conditions.
Fall Color Development
September-October (6-8 weeks)Foliage intensifies dramatically to deep crimson-red and burgundy; white flowers mature to bright red berries
Stop fertilizing to encourage color development. Reduce watering as temperatures cool. Berries provide winter interest and food for birds.
Winter Dormancy
November-February (12+ weeks)Deep burgundy-red foliage persists; plant appears semi-dormant with minimal growth; red berries remain attractive
Little intervention needed. Prune in late winter to remove dead growth or shape as needed. Minimal watering in colder zones. Protect from extreme cold in zone 6.

Fun Facts
- 🌱 Nandina Obsessed was developed specifically for its enhanced red foliage color intensity and more compact, slower-growing habit compared to standard Nandina domestica, making it ideal for smaller landscapes and containers.
- 🌱 Despite the common name 'Heavenly Bamboo,' Nandina is not a bamboo at all but a member of the Berberidaceae family; the feathery foliage superficially resembles bamboo but the plant is completely unrelated.
- 🌱 Nandina berries remain on the plant through winter and actually improve in flavor and color after frost exposure, and birds often wait until berries soften in late winter to consume them, extending the plant's wildlife value.
