Hello, I have a question about what is normal for Norfolk Island Pines.
Mine is about 3 ft. tall and for the most part it looks healthy but I have noticed small brown spots and individual needles turning brown. (Picture shows the most affected branch. Most branches are affected but not as much as the one pictured) I am wondering whether or not this is something to worry about.
I'm also wondering how much lower branch drop is normal.
I don't get much natural light in my apartment and it was way too dry this last winter. So I realize it may be reacting to those conditions. I also made the mistake of putting it by the radiator until, about a month ago, it dropped 4 lower branches. On a warm day, I took it to my parents' house where there are no radiators and more natural light. The humidity is rising here in MN and no more branches have dropped but today it lost 15 or so "leaves" from the lower branches. Is this normal?
