Norfolk Island Pine (Araucaria heterophylla)

This plant is often incorrectly identified as Araucaria excelsa, especially in older references.

Unfortunately Norfolk Island pine is very tender to cold and will begin to sustain damage at temperatures below 40F beginning with discoloration of foliage. Temperatures around 30F with frost will start to kill it back and if it gets any colder it can kill it. Depending on where you live in Michigan the average winter low there is anywhere between 0F and -30F.

If I were to chp the top part off would it stop it from growing upwards or would it just kill it? I really like the tree, but don't have the room for it to grow too much more. Thank you.

Some yard Norfolk-Island-Pine trees if they are leaning and damaged and are cut down they can sprout new suckers from the stump. Topping or cutting off the top parts of all kinds of trees is not good at all for trees outdoors in the ground because they form many new twig shoots which make them have weak growth, pests, and break off easy in the wind and sometimes die. But this indoor tree you will need to trim it sometime. It is usually not recommended but I don't think it will hurt it as long as you make a clean cut but dont make many cuts because it can waken and stress the tree the more cuts you make, especially larger cuts. Removing top growth would result in a tree without its top, thus destroying its natural symmetry. You cant control the growth speed by pruning, and No growth is likely to result from the cuts. If you do this, make a clean cut with sharp pruning shears. Keep soil just slightly damp and not wet and it should do good.
