Norfolk pine

Question

The plant I have is growing good but the arms are so long they are hanging down. Do I need to trim them back or not to help it thicken up?

Answer 1

There is little to be done with the growth on Norfolk Island Pine.

The only pruning should be cutting off browning or dead branches.

All growth stops at the point of pruning on a Norfolk Island Pine.
