Barberry with bright green leaves instead of expected deep purple-red: first, check if it's new spring growth. All barberries emerge green, darkening as leaves mature. Wait 4-6 weeks.
If established foliage stays green, it's stress-related: insufficient light (barberries need full sun for best color), high soil pH, or nutrient deficiency (especially phosphorus). Test soil. Amend with sulfur if pH >6.5. Fertilize with low-nitrogen, high-phosphorus formula.
Some cultivars are naturally greener. Verify the variety name. 'Crimson Pygmy' and 'Rose Glow' color best in full sun.
