color loss on Croton
Quick answer
If your Croton has color loss, the most likely cause is: Codiaeum variegatum requires high light intensity (500+ foot-candles) to maintain vibrant leaf variegation. Insufficient light triggers chlorophyll overproduction as the plant compensates for reduced photosynthesis, causing colorful variegated patterns to fade to green. This is a photoprotective response distinct from sunburn, which causes bleached white patches.
Start here:
- 1. Move to south-facing window with 6+ hours of direct sunlight daily
- 2. Supplement with full-spectrum LED grow light (6500K, 200+ foot-candles) for 12-14 hours daily if natural light is insufficient
