Norfolk Island Pine Care Araucaria heterophylla Question from Alex: Hello, I have a small about 7 foot Tall and 5 feet in width Greenhouse. Its place outside next to my camper and we live in southern IL. It does get cold and windy outside here. I was wondering if I should put my Larger Norfolk Pine along with the plants inside the greenhouse? It gets humid in there and never goes under 40 degrees inside. Would that be safe? The greenhouse kept 30 degrees in 17 Degree weather a few days ago. None of my plants froze or anything. Norfolk Island Pine Answer: Hi Alex, Recommended low temps for the Norfolk Island Pine are about 40 to 45 degrees F. You may see some damage or growth problems at lower temps but it should survive okay. If you think it may get colder in your greenhouse, you can help protect your tree by covering with clear plastic to let in light and keep in some warmth. Then place in your greenhouse. That should give it enough protection from the cold weather you have...
