low light and Boston Fern
Quick answer
If low light is what's going on with your Boston Fern, the most likely cause is: While Boston ferns tolerate lower light than many plants, insufficient light causes slow growth, pale fronds, and leggy, weak stems. In very low light, ferns become susceptible to other stressors and may gradually decline. They need bright indirect light for vigorous, healthy growth.
Start here:
- 1. Move fern to a location with bright indirect light�east or north-facing windows are ideal
- 2. If natural light is limited, supplement with a grow light for 12-14 hours daily
