Answer
Hi Pat,

The symptoms you described are not specific enough to identify a particular cause. It is most likely a light or a watering problem.

Norfolk Island Pines should be in front of a moderately sunny window where they get a few hours of direct sunlight each day. A south-facing window may provide too much light and if it is more than a couple of feet from any other window then that will not be enough light.

Watering assumes that the tree is correctly potted so that it is moderately potbound. If so, then water thoroughly as soon as the top quarter of the soil feels dry.

If the tree was recently repotted, then that is probably the reason it is not doing well because extra soil tends to retain water for too long and cause root rot.

Finally, very warm, dry air can cause needles to turn dry and fall off. Temps below 70 degrees F. are important.

Fertilizer and changing the soil will only aggravate the problem.

I have written an article on Norfolk Island Pine care that I will email for free to you (or anyone else) who emails a request to me at wcreed@HorticulturalHelp.com.
