Brown Spots on snake plant
What's Happening
Snake plants adapted to shaded forest understories possess limited photoprotective mechanisms against intense direct sunlight. When moved from low light to direct sun without acclimation, leaf cells experience photooxidative damage. Chlorophyll breakdown and cell membrane rupture create irregular brown spots, often starting at leaf edges where light exposure is most intense. Unlike fungal spots (which spread), sunburn damage is static and corresponds exactly to light exposure patterns.
How to Fix It
- 1
Move plant immediately to bright indirect light location
- 2
If gradual acclimation is needed: start with 1 hour direct sun, increase by 1 hour daily over 10-14 days
- 3
Trim affected leaf sections with sterile scissors for aesthetics
- 4
Rotate plant weekly to ensure even light distribution during recovery
- 5
Consider sheer curtains for south/west windows to diffuse intense afternoon sun
How to Prevent It
Always acclimate to new light conditions gradually over 7-14 days. Position 3-6 feet from south/west windows or use east-facing windows for gentle morning light. Monitor leaf temperature—if leaves feel warm to touch, light is too intense.
