Keeping Christmas (A)Live

Many of the new permanent (not artificial, please) holiday greens are incredibly realistic. Still, there are those of us that cherish live greens and the fragrance they bring to the holidays. With that desire comes the challenge of keeping those greens fresh as long as possible. Some easy tips to achieve that goal:

The tree - How long are you going to have the tree up? Are you the family that puts it up the day after Thanksgiving and takes it down in January? Or, do you have it up for 2 weeks and then you're off to the Caribbean? Buy accordingly. In order of needle retention, shortest to longest: Balsam fir, white pine, Canaan fir, Fraser and Nordman fir, Noble and Concolor fir.

Buying early, but not decorating for a while? Take it home and store it out of the drying effects of wind and sun. An unheated garage meets those criteria. Don't lose height needlessly by cutting before it goes in water. Myth: Placing it in a bucket of water outdoors that quickly grows cold does nothing for keeping it fresh before stand set-up.  

If you're going to set it up right away your garden center may make the fresh cut for you. Making your own cut? It can be as little as 1/4". Like a cut flower, your tree just needs freshly exposed cells for water uptake. Once that cut is made you have up to six hours (1-2 hours is far better) to get the tree in the stand and in warm water.

Literally the "Last Stand" you'll ever need

Get a stand that holds good quantities of water. Love the Bowlin stands- huge reservoirs and are so heavy and stable they can could go through a tornado and remain standing. Well, almost. I've been unable to uncover any research that proves commercial preservatives make any difference in tree freshness. Forget aspirin, bleach and the home remedies. Do consider spraying an anti-transpirant like Wilt-Pruf on the underside of the needles, letting it dry in the garage before bringing it inside for set-up. This should make a difference.

 Helps to keep trees and greens fresher

So, the tree has a fresh cut and is in the stand. Always add warm water. Be vigilant the first few days. Check a few times a day to make sure the stand never goes dry. Generally the tree will become hydrated and slow its uptake. Still, water levels should be checked at least daily throughout your tree's time indoors. By the way, when the holidays are over think about cutting the branches off and using them as mulch over ground cover or perennials- a great way to recycle.

Spray the underside where moisture is lost

Wreaths and roping - Wilt-Pruf can be used on all greens, whether they're to be used indoors or out. Like the tree, try as best you can (and I do know it can be difficult) to spray the underside of leaves where the water loss actually occurs. Regardless of what precautions you take, placing greens near fireplaces, radiators and vents takes a toll. Know that balsam is wonderfully fragrant, but has a thin needle that dries and sheds indoors. White pine roping will eventually discolor, but needle drop is minimal.

Live plants in pots outdoors - Treat boxwood, Alberta spruce, really any tree or shrub in a pot, as an annual. If it's alive next spring, what a great bonus! Generally, the smaller the volume of soil the more apt it is to freeze and damage the roots irreparably. I recommend 24" (all directions) containers as giving best chances for success. Use Wilt-Pruf and water periodically if plants are under an overhang, or we experience a dry winter.

Live Christmas trees keep on giving

Live Christmas trees indoors - This references the sustainable practice of decorating potted trees indoors for planting after the holidays. Three things you should know:

* Predig the hole before the ground freezes. Store the soil where it won't freeze. Mulch the hole with straw to keep it from freezing before you plant the tree.
* Limit your tree's time indoors. I like 1 or 2 days in an intermediate cool area (like a garage or unheated porch), 5 days maximum inside, 1-2 days back in the cool area again, then plant.
* Know that cute 4-5' evergreen in a pot is a lot of weight to be hoisting back and forth, in and out, up and down stairs. But it is very cool see it years later in the garden and say, "That was our Christmas tree in 2015!"

Happy Holidays, all!
