Norfolk Island Pine

Question

I have a Norfolk Island Pine that is about 9 ft tall. Can I plant it outside? Temperatures can get as low as 20 degrees here in winter.

Answer 1

Unfortunately, Norfolk Island pines are not cold-hardy and cannot be planted outside if the temperatures get below 35 degrees. A botanical garden I worked for had one die even inside a heated greenhouse one winter.
