It did my heart good when a friend told me this week that she and her husband had bought a real Christmas tree this year after three or four years decorating an artificial one.
"It's beautiful," she said of her new Fraser fir, enthusing about the quality of the trees at Johnson's Garden Center, where she bought hers.
I came back from Thanksgiving to find my house smelling wonderfully of balsam fir but seeing that my Christmas tree had shed more needles than I anticipated.
I thought I had a really good idea this year: Put the tree in a nice bucket rather than in my shallow tree stand, fill the bucket with water, crank down the heat, and feel free to leave for several days.
Never miss a local story.
When I came home the one good thing was there was still plenty of water in the bucket. But I wondered: How long does it take for sap to seal the cut on the trunk of the tree, preventing it from taking up water? I had the bottom of my tree cut before I left the nursery where I bought it, and I did not repeat the procedure when I got home.
When I got back to work I read a story about a Wisconsin tree scientist who never used to water his Christmas tree on the reasoning that trees stop photosynthesizing when they're cut from their root systems. His wife, however, would water the tree behind his back.
This tree man, Les Werner, an associate professor of forestry at the University of Wisconsin-Stevens Point, finally decided to test whether watering mattered, according to the story in the Milwaukee Journal Sentinel. A tree farm donated 54 fresh-cut trees of four different species for a four-week study.
Werner found, as most of us have by experience, that unwatered trees lose a lot of moisture over time, while watered trees maintain theirs. He found that after about a week, a tree will respond to the cut on its trunk by excreting resin to naturally seal the wound. Then it no longer takes up as much water.
The newspaper story reads: "Cutting a few inches off the trunk before putting it in the stand opens the capillaries to allow the tree to draw moisture up the trunk and into the needles," said Werner. "The water level should be two to three inches above the cut."
That made me wonder if I had left too much water in my bucket.
The study also ranked the four varieties of trees on their needle retention. Fraser firs ranked best for water uptake, sap flow and needle retention, followed by Balsam fir, Scotch pine and Black Hills spruce (which we in this part of the country can buy at local nurseries as living Christmas trees to be planted in the yard, not as cut trees in Christmas tree lots).
Werner also said that clean water — with no additives — works best in tree stands.
I found that I could balance my tree in the middle of its bucket without the benefit of those pullies and screws in a regular stand that hold the tree straight. The tree can face only one particular way to avoid tilting, thus perhaps not presenting its best side to the world, but I figure that adds to the naturalness of it.
To add to my unusual — perhaps, more accurately, simplistic, lazy or minimalist — tree arrangements this year, when I ran out of lights near the bottom, I pruned the boughs that would have been in the dark. I then festooned some windowsills and the area around my creche with the boughs, giving me more ways to sprinkle needles along the way.
