Q: The top of this tree is growing great but the brown limbs are traveling upward. Should we cut them off or what should we do?
A: It is typical for Norfolk Island Pine to drop lower branches when it is growing in low light. That’s why your limbs are turning brown. Consider moving yours to the brightest spot in your house.
Or you could put it in a shady spot outdoors each year from spring to fall and it would probably do even better.
