What do you do with a Norfolk pine that is about to touch the ceiling? Is it possible to trim it down without hurting it?
You must have provided a great home for your Norfolk Pine.
Pruning isn't really a great option for your plant. Cutting off the top, just leaves an plant without a top.
An option they I suggest when this question comes up is possibly donating the plant to a business or school. They have generally a larger space for a plant.
