Georgia-grown Fraser fir Christmas trees on the horizon

When it comes to Christmas trees, Fraser firs top the list. But Georgia Christmas tree farmers can’t grow the tree due to the state’s mild winters, and must buy Frasers from North Carolina to sell to their Georgia customers. A University of Georgia horticulturist wants to change that.

Fir trees produce new growth very early in spring, which makes them susceptible to freeze damage. “When new shoots start to grow in early spring, they are often severally damaged or killed by the below-32-degrees temperatures that we often have during the spring here in Georgia and much of the Southeast,” said Mark Czarnota, a horticulturist with the UGA College of Agricultural and Environmental Sciences.

Frasiers + Momis

Using a $30,000 U.S. Department of Agriculture grant, he wants to deliver another option to Georgia Christmas tree farmers. He is grafting Fraser firs onto Momi firs in his greenhouses and fields on the UGA campus in Griffin, Ga., and working with Georgia Christmas tree growers in Lovejoy and Terrytown.

A native of Japan, the Momi fir (Abies firma Siebold & Zucc.) made its debut in Georgia in the early ‘90s. “The planting culture of Momi fir is very different from most other Christmas tree species that growers were currently growing,” Czarnota said. “Needless to say, Momi firs first introduction was a miserable failure.”

With proper management, though, Momi firs can grow in Georgia. The biggest stumbling blocks are adjusting soil pH to around 6.5 and providing irrigation to young plants for two or three years, he said.
Faster growing is more profitable

Growers in the Southeast don’t like to hear that it takes six to eight years for the tree to reach a desirable Christmas tree size. Traditional Georgia Christmas tree species like Leland cypress and Virginia pine mature in three to four years. When it comes to growing Christmas trees, the sooner a tree matures, the sooner the farmer can take it to market.

Fraser firs will grow in north Georgia, but the downside is that the tree is affected by the root fungus phytophthora. If not treated, it can kill infected plants.

A new Christmas, landscape tree

Czarnota hopes to combine the Momi fir rootstock and Fraser scion, or shoot, into a tree that will grow throughout much of Georgia and the Southeast.

“I don’t expect it to take over the market, but it will be a great addition,” he said. “A lot of work needs to be done in selecting good Momi grafting stock for desirable uniformity. It’s a lifetime project, and great potential exists in trying to cross Momi fir with other firs.”

Researcher John Frampton at North Carolina State University works on the tolerance of Momi fir to phytophthora. He has found the plant is very tolerant to the root disease.

North Carolina fir growers have a very difficult time dealing with the fungus. Frampton is trying to cross Momi and Fraser fir to breed a hybrid phytophthora-resistant fir. In the meantime, he encourages North Carolina growers to plant Momi-Frasier grafts, Czarnota said.

On-farm research

One of Czarnota’s collaborators, 82-year-old Earl Worthington, grows Christmas trees in Lovejoy, Ga.
“Dr. Worthington was one of the first growers to try to grow firs in the Georgia piedmont region,” Czarnota said. “He actually got greenhorns like Dr. Frampton and me moving in the right direction, and has been a wealth of knowledge for many Christmas growers here in the Southeast.”

Worthington hopes to someday grow enough Fraser firs to avoid buying from growers in western North Carolina. He bought 300 Fraser firs this season.

Worthington has been grafting Fraser firs onto Momi firs for the past 15 years. In the beginning, it took 10 years for him to grow an 8- to 9-foot tree. “I can now produce a 5- to 6-foot tree in five to six years,” he said.

The problem he now faces with his grafting efforts is the inconsistencies. “Some (of the trees) turn out very yellow, some very stiff, some are green all year, some flush early and some flush late,” he said. “Grafting trees is definitely a project for someone with patience.”

Potted Christmas trees keep giving for generations

Families have fun choosing and decorating their Christmas trees. The twinkling lights, the bright colored ornaments, the handcrafted decorations the kids make and the yummy candy canes along with that fresh pine smell add a special glow to the holidays. But after the holidays, cleaning up those messy shed needles or dragging that tree out of the house isn’t as glorious.
There’s the age-old question: What do I do with the tree now?

Many retailers that sell fresh-cut Christmas trees also offer shredding service after the holidays. While shredded trees make excellent mulch for the landscape, one University of Georgia expert suggests consumers think about what to do after the holidays before they buy the tree.

“If you don’t need a huge tree, and a 6- to 7-foot tree will work, you can go to any garden center and look at the live conifers available,” said Matthew Chappell, a UGA Cooperative Extension horticulturist. “There are so many choices. Cupressus, Chamaecyparis, Thuja, Leyland Cypress, Cedrus and Juniperus all will work as Christmas trees.”

Using a live potted tree doesn’t require more work than a cut tree, just a little different care. There are two big points to remember, he said.

“The tree should only be inside for a week to 10 days,” he said. “Placing the tree inside will shock the tree because when you move a tree inside, you are significantly altering the growing environment to lower light, drier and warmer conditions, especially if you put the tree near a woodstove or fireplace. This means the tree should be removed the day after Christmas.”

Also, remember to water. “The tree will need to be watered every 1-2 days until water drains through the bottom of the pot,” he said.

Live trees can be economical, too. In the Atlanta area, a 6- to 7-foot live tree in a 15-gallon container at a local retail outlet sells for between $100 and $140. A 15-gallon 6-foot Leyland Cypress goes for between $90 and $100 at local nurseries and tree growers. Both are comparably priced to fresh-cut trees. Call around to check prices in your area.

Considering the benefits of trees in the landscape to provide shade, screening or improved air quality, a live tree is one holiday decoration that can last a lifetime. “This could be a great new ‘plant a tree for the environment this Christmas’ movement,” Chappell said.

For information on planting, pruning and caring for a landscape tree, read the UGA Extension publication “Trees for the Landscape: Selection and Culture” online at http://pubs.caes.uga.edu/caespubs/pubs/PDF/B875.pdf or call the UGA Extension office in your county at 1-800-ASK-UGA1.

Fresh Trees Liven Up the Holiday Season

Charlie Brown trees and brown needles don’t have to haunt you this holiday season. With the help of a few tips and tricks from the University of Georgia, your Christmas tree will be fresh long after the celebrating is over.

Before picking out a tree, decide the size, species and how much you want to spend. Then, select a fresh tree that has been properly maintained and cared for while still on the lot.

“Taking really good care of a tree at home after you purchase it does not reverse the abuse it can get waiting on the lot,” said Don Gardner, the UGA Cooperative Extension coordinator in Glynn County.

Picking the freshest tree

Look for trees displayed in the shade or under a tent and in tree stands with water in them. The sun and wind pull water out of the tree, so good growers will keep their trees out of the sun.

To find the perfect tree, look for one with uniform distribution of branches and no holes in the needle canopy. Also make sure it smells fresh.

“The more water stress the tree is under, the less fragrance it emits,” Gardner said. “Fresh trees smell better.”

Test freshness by gently pulling several of the branch ends through your hand to see how many needles fall off.

“Don’t try to strip the needles off the branch,” said Gardner. “Stroke it as if it were a cat’s tail -- a cat you like. All cut trees will lose some needles, but the fewer the better.”

From the farm

Although there is little difference between buying a tree from a local tree farm or from a commercial retailer, buying from a farm is great for making family memories and helps keep local farmers in business, Gardner said.

“Loading everybody into the truck to pick out a tree at a farm is a fun day itself,” Gardner said, “and the more family members involved in picking out the tree, the more eyes there are making sure the tree stays watered.”

Many Georgia tree farms also hold family events and offer refreshments during farm visits.

“Buying local helps keep your friendly neighborhood Christmas tree grower in business and keeps good farmland in production,” Gardner said. “Buying from a local tree farm is definitely the ‘green’ thing to do.”

Taking it home

To get your Christmas tree home safely, have the seller tie it up and put the tree inside your vehicle if possible. If you put the tree on your vehicle rooftop, bring a few large plastic bags and put the tree in the bags stump end first. Then face the stump end forward on your rooftop. This will reduce wind blow-drying effects and water loss.

Many sellers will offer to trim off the stump end of the tree, Gardner said. Instead, wait until you get home to do so.

At home, trim low limbs and cut the tree stump at an angle with a sharp saw. Gardner advises running water over the stump while cutting it.

“While making the cut, have a helper hold a running hose over the cut so you are virtually making the cut under water. This is the difference between a tree that lasts two weeks and a tree that lasts two months,” Gardner said.

Then, quickly move the tree into your house and into its stand. Immediately add water until the tree stand is about two-thirds full. Then secure the tree into the stand.

After your tree is in place, keep it watered. Be sure the trunk’s cut surface is never exposed to the air.

“A new tree may surprise you at how much water it will suck up and how quickly it will do it,” Gardner said. “A 10-foot tree can use over a quart of water in the first three hours.”

Water your tree at least three times a day during the first few days and twice a day thereafter.
