Variegation Sunburn on rhaphidophora tetrasperma
What's Happening
White variegated tissue on Rhaphidophora tetrasperma contains no chlorophyll, eliminating photoprotective mechanisms. When exposed to direct sunlight or intense artificial light, the white cells undergo photooxidative damage—essentially sunburn without protective pigments. This appears as brown, crispy spots specifically on white/cream sectors while green tissue remains unaffected.
How to Fix It
- 1
Immediate relocation: Move to bright INDIRECT light only—never direct sun on variegated tissue
- 2
Assess damage pattern: Brown spots on white sectors only = sunburn; green tissue damage = different issue
- 3
Trim affected areas: Use sterile scissors to remove crispy brown tissue for aesthetics and prevention
- 4
Increase humidity: Raise to 70-80% to support cellular repair in damaged variegated cells
- 5
Grow light adjustment: Maintain 18+ inches distance; use hand-heat test (no warmth felt at leaf surface)
What You'll Need
How to Prevent It
Position 4-6 feet from south-facing windows; use sheer curtains to diffuse direct sun; maintain 60%+ humidity to support stressed tissue; avoid fertilizing damaged plants; acclimate gradually over 7-10 days when relocating.
