Welcome to NGA,
@noniec !
Can you post a photo of your tree? And maybe add your location to your profile? (both would be helpful
)
I agree that it sounds like your Norfolk Pine needs to be re-potted. The fact that it's getting new growth is a good sign, though.
And, contrary to Philip's advice... if you live in the north like I do, there isn't much choice as far as it being indoors... and they do make very good house plants.
