Recently Purchased New Guinea Impatiens Leaves Are Turning Brown

Question From: Tomahawk, Wisconsin, United States
Q: We bought a new guinea impatien plant. It is in full sun. I watered it yesterday and now I noticed that the leaves are turning brown. What could be causing that?

A: Sounds like sunburn to me. If you purchased it in a greenhouse and failed to harden it off, it probably is suffering from sun and possibly windburn. Best And Happy Yardening, Nancy
