Is it possible to rejuvinate Norfolk Island Pines once most of the needles have turned brown? These trees (5 stems all rooted together) came to me as a "Christmas Tree" about ten years ago. I have transplanted them to larger pots as they've grown. They've even done well on a closed-in porch during the cold dampness of nortwest Washington State winters. They've also lived on that same porch in warm months but can get some pretty harsh direct sun during parts of a day. Is it possible they've gotten "burned" by too much direct sun? Note: Needles on branches have turned brown but are not falling off individually... Any Thoughts? Thanks in advance! Sorry can't get pictures today but will tey tomorrow.

This is possible... there are so many reasons why these can turn brown. Sometimes it is even normal for the ones at the bottom to do this.Here is an article that will help: https://www.gardeningknowhow.com/houseplants/norfolk-pine/norfolk-island-pine-care.htm
