Houseplants and UV-Coated Windows: What You Need to Know

Coatings Can Reduce Light Enough to Harm Plants

If leaves yellow, the UV coating is blocking too much photosynthetically active radiation.

Solutions

• Add fluorescent lights: new bulbs in floor lamps, or 2-tube fixtures on 14-hour timers.
• Only supplement plants showing yellowing—some tolerate lower light.
• Summer outdoors is great for all.
