Crayon-green Christmas Trees Brighten Holidays

Coloring Christmas Trees
COLORING CHRISTMAS TREES provides long-lasting, safe color for holiday decorators. Dave Moorhead, a UGA Extension Service forester said the tree needles absorb the color and stay green through the holidays. Though the needles stay green, it's not a reliable indicator of freshness. Check the water level in the tree stand daily and add fresh water to keep the water level above the bottom of the tree trunk.

Even shoppers who insist on a natural, live Christmas tree almost always take home an artificially colored tree. And in this case, what you didn't know won't hurt you, says a University of Georgia scientist.

"The pigment in the colorant is the same thing you find in children's crayons," said David Moorhead, an Extension Service forester with the UGA D.B. Warnell School of Forest Resources.

"There's not a problem with the colorant in terms of its being a toxic material," he said. "It's a very safe product."

Moorhead said farmers spray the colorant on some tree species to help them stay a rich, dark green. Many trees lose their color during late fall and may turn yellowish- or reddish-green. The spray-on pigment keeps them green for the holidays.

Tree farmers prepare their trees with colorant long before the holiday sales begin.

"We've found that gives the colorant on the tree time to mellow out and look more natural," said Judy Brewer, who sprays trees on her Liberty County farm in early September.

Brewer said most shoppers at her family's 25-acre choose-and- cut farm prefer the colorized trees. "Even if they say they want an unsprayed tree," she said, "they can see the difference, and most of them change their minds."

Once farmers apply the colorant, it stays put, Moorhead said. "The trees typically are very well cared for in the field," he said.

Applying the colorant early allows the color to dry completely on the needles and stay colorfast through the holiday season. The color won't come off on you, your children, pets, gifts, ornaments or other decorations, Moorhead said.

Brewer said the tree needles absorb the colorant and gain some protection against moisture loss. "It's kind of like makeup for trees," she said. "It really beautifies and protects them."

The colorant, though, won't keep the tree fresh through the holidays. The trick to doing that is to keep the tree stand filled with plenty of water. Sugar, bleach, aspirin or clear sodas can't help the tree take up water. Dry trees are much less fire resistant, and just a spark can set them ablaze.

The holiday season can be a time of anticipation and joy, but balancing multiple commitments and personalities across families and friends can be a source of stress for hosts and visitors alike. Like preparing parts of the meal ahead of time to spend more of the holiday with guests, taking time ahead of the day to set expectations can go a long way to ensuring enjoyable gatherings, said Ted Futris, University of Georgia Cooperative Extension specialist and professor of human development and family science in the College of Family and Consumer Sciences.

The women and stress behind rural farming in America 11/19/24 Leigh Hataway
Recent research from the University of Georgia suggests the unique stresses from farm life may be taking a toll on one of the pillars of the families that make your dinners possible: the women who keep farming families running. “If we don’t control our food sources, we don’t control our health and safety,” said Anna Scheyett, lead author of the study and a professor in UGA’s School of Social Work. “It’s a matter of national security that farmers survive in the United States. And one of the big factors in helping farms survive is women.”

Wheat breeders spend years meticulously crossing varieties to coax the best traits out of each species, carefully propagating plant varieties that are healthier, heartier and better suited for the environments where they are grown. Professional brewmasters are equally painstaking when choosing the components that will give their beers a specific flavor profile.
