norfolk pine

Zone Denison, IA | [email protected] added on August 16, 2016 | Answered

Starting to yellow with tips turning brown, from bottom to top. It's an older plant in an east sunroom. Just started having problems this late winter so added a humidifier close to it but has continued to yellow. Has been in the same pot for quite a few years.

It is possible that humidity is indeed the problem, since this plant enjoys rainforest-like conditions. Also check the following articles to see if any of the symptoms match:
