Want to avoid buying a Christmas tree only to throw it away? You could buy a “living” Christmas tree. A spruce, fir or pine in a decorative pot that you buy for Christmas then plant in your back yard at New Year’s. That sounds perfectly nice… for those of us who live in climates that make January plantings possible.

However, even if I felt like preparing a planting hole in October before the ground freezes, then carefully protecting it with mulch, somehow, by January, where temperatures average around 0°F (-18° C). I don’t feel like tunneling through a meter of snow to find the planting hole, so I’d rather pass on the idea. Besides, no matter how carefully I try to plan it. I can’t see squeezing a spruce tree which can potentially reach 100 ft (30 m) or more in height and 15 ft (5 m) in diameter into my postage stamp back yard.

A Subtropical Christmas tree?

That doesn’t mean I can’t have a “living” Christmas tree. It simply means I can’t have a living hardy Christmas tree. What I can and do grow is a living subtropical Christmas tree.

I bought my Norfolk Island pine or Norfolk pine (Araucaria heterophylla) as a tiny plant in a 4-inch pot over 10 years ago. It is now almost 2 meters high and is one of the most magnificent foliage plants you can imagine. It bears long, dark-needled branches which, on older stems, have a slightly pendant habit. Each year, in spring, it produces a short stem (about 6 inches/15 cm) in height from the tip of the plant, then a new tier of branches which spiral out from the main stem like the spokes on a wheel.

Of course, mine is now so tall it is reaching the limit of its useful indoor life. It will probably have to be donated to a local greenhouse within a few years. I don’t feel that 12 years of use is all that bad for a plant that only cost me $1.49 (and possibly, in all that time, half a bottle of fertilizer and two bags of potting soil). Do you? In fact. I doubt if most artificial trees stay in good shape that long!

Decorations On a Norfolk Pine?

Do I dare decorate this living object at Christmas time? You bet I do! In fact. I started decorating it the first year, when it was barely a seedling, with tiny ornaments too light to do any damage. Now that it is big. I don’t hesitate to use any ornament that would normally be used on a Christmas tree. The only exception is the medium size Christmas lights that are usually used on cut indoor trees. I feel these give off too much heat and could damage the needles, so I use the tiny twinkle lights instead. I also avoid artificial snow. When my tree is fully decorated and lit for all the world to see. I doubt if anyone would notice it wasn’t a traditional fir or pine.

Growing Conditions

Norfolk Island pine is not even a difficult houseplant to grow. It prefers bright light at all times and even full sun in the winter, and a soil that is kept constantly moist but not soaking wet. In other words, about the same care as the average foliage plant. Feeding is only necessary from spring to summer, when the plant is actively growing. I repot about every two years into regular potting soil. Interestingly, the root ball has remained quite small for the size of the tree, giving the impression that it is underpotted.

Humidity Is the Key

High humidity (which I get for free simply because I have so many plants in my apartment) is an important factor, as it helps keep the lower branches from drying out. Although most books will tell you that cool winter temperatures are a must. I haven’t found this to be tru. My apartment stays pretty well between 68° and 80°F (18° and 27°C) year-round. I believe, though, that the secret is my high humidity. If your home is dry and nothing can be done about it, it is better to keep night temperatures quite cool (50° to 60°F 10 to 15°C) if you want your Norfolk pine to stay in good condition. Once the lower branches do dry out and fall off, they will not be replaced.

Room to Grow

When your Norfolk pine does get too big for the available space – 12 years from now!—there isn’t much you can do. You could try rooting the top shoot, but this is very difficult and home conditions are not ideal for this procedure. Side branches are easier to root, if only because there are so many of them that, out of a dozen cuttings, one is bound to take. Unfortunately, side branch cuttings result in creeping plants rather than upright ones: not at all the effect you would want. The only solution is to buy a new plant. (Commercially, araucarias are grown from seed.)

Alternatives to Norfolk Pine

Araucaria heterophylla is not hard to find. Most greenhouses offer it, especially at Christmas time. Should you want more variety in indoor evergreens, there are few other subtropical varieties around. A. bidwillii is one. Called bunya pine, it is a spiny version of A. heterophylla with a less well-defined form. There is also Podocarpus macrophyllus, the “yew plum” or “Buddhist pine”, a conifer with long, flat needles that is particularly easy to grow indoors, although it may need a bit of pruning (which it readily supports) to change it from a bushy form to a pyramidal Christmas tree one. Finally, Hesperocyparis macrophylla ‘Goldcrest’ (formerly known as Cupressus macrocarpa ‘Goldcrest’) is a pyramidal golden cypress which can also be grown with great success indoors and makes an attractive Christmas tree.

  1. Norfolk Pine:Excellent structural/furniture timber for your future grand children

  2. We quit putting up a tree years ago, after my children grew up and moved away. And you have reminded me of the years my mom and dad would a root ball pine and we would plant it on my birthday after Christmas (Jan. 10).
    Now, I think I will buy a small indoor living tree. You’ve inspired me! Live the varieties you’ve mentioned but since we live in Florida, USA, I will have to see what my local growers offer and choose from their stock. Thank you again!

  3. Yes love the myth of doing a potted tree in a cold climate. And much as I love a real tree it does require lots of rearranging and mess to clean up. Last year we used a big Euphoriba tirucalli (Sticks On Fire). We wrapped the pot in our tree skirt, added battery powered twinkle lights and some smaller decorations. It worked really well and no mess or tree to dispose of afterwards when the weather is too cold to hold the front door open for long. This year it will be a couple of big gold Cupressus.

  4. Almost all of the Italian stone pines and Aleppo pines that become problematic, and often VERY problematic, in home gardens started out as living Christmas trees. They are so cute and innocent while small and potted and decorated, so people plant them in the most random situations, and often up against the foundations of their homes. Some families make a tradition of planting their Christmas trees annually. By the time the oldest becomes big enough to be a problem, they have already planted several. Arborvitae and other more manageable evergreens are more practical. However, because some are ‘forced’ in nursery conditions, they must be planted into larger pots soon after Christmas, and are likely to get shabby within the next year prior to the next Christmas. Bunya bunya is a rare tree, even here where they can live outside, and is too wickedly spiny to be brought inside as a Christmas tree!

  5. It is too hot in zone 8a, South Carolina, Cypress, cedar, and pine varieties are best for here, no furs or Blue spruce, here.

      That’s what I thought but the Norfolk are doing fine and getting taller every year. Except for brown tips. Guess I will just see if things improve with our cooler weather. I didn’t understand your text tho+ blue spruce here(?)s south Carolina their best home? Were you talking about the Norfol? And cypress cedar and pines for here(?) No furs or blue spruce here-where is here? Can u pls clarify. I’m in southern calif I honestly couldn’t figure out what u meant. Thx a bunch

    I planted a couple of Norfolk pines about 5-8 years ago never expecting them to thrive since I live in a warm dry climate. They were leftover holiday trees tho-andi figured I had nothing to lose. They are now 10-12 feet and look pretty good except the tips of the lower branches are yellow/brown. Wondered if this was lack of light? They are in a filtered light area but it’s 100 in the summer and figured they couldn’t take any more. I water them 1-2x a week Any ideas?

    Applauding another of your columns, Mathieu! Although not a fan of Christmas, we’d observe the holiday while the kids were young so they could feel culturally connected with peers. We’d alternate between using the Norfolk and buying living trees. Happy to say there are large, gorgeous Spruce trees on my acreage from those living trees.
