Light-Stress on rubber plant
What's Happening
Ficus elastica is native to tropical rainforests where it receives bright, filtered light through the canopy. Indoors, insufficient light (below 1000 lux) triggers etiolation - elongated, weak stems with small leaves spaced far apart. The plant stretches toward light sources, depleting energy reserves in the process. Variegated varieties are especially sensitive and may lose variegation in low light.
How to Fix It
- 1
Move to location with bright indirect light (2000-5000 lux)
- 2
East or west-facing windows with sheer curtains are ideal
- 3
If using south-facing window: position 3-5 feet back or use sheer curtain
- 4
Supplement with grow light if natural light insufficient (12-14 hours daily)
- 5
Rotate plant weekly for even light exposure
How to Prevent It
Position in bright indirect light from day one. Use light meter app to verify adequate illumination (minimum 1500 lux). Avoid dark corners or north-facing windows without supplemental lighting. Maintain consistent light levels year-round; don't move between bright and dim locations frequently.
