Among the pleasures we enjoy in December is choosing a Christmas tree. The choices are many: the firs (Douglas Fir, Fraser Fir, Balsam Fir), pines (Scotch, Eastern White), red cedars, and spruce (Colorado Blue, Norway, Concolor). Throughout the United States there are more than 35 different evergreen species grown for the holidays. They are available either cut, in containers, or balled and burlapped.
If you choose to purchase a cut tree, try to prevent the cut section of the trunk from being exposed to the air for more than three to six hours; it should be put into a container with water as soon as possible. Next, trim off the lowest branches which might interfere with the tree’s staying upright in a stand, and then remove ragged branch tips or unattractive branches. Saw off an inch of the trunk so the tree can absorb water freely, and fasten it to its stand, which should contain plenty of water. The water, especially at first, should be replenished often.
Artificial Christmas trees are often made of PVC, a dangerous chemical, which is not biodegradable, and does not have the wonderful fragrance of a real tree. However, they may be used for many years and are maintenance free.
A live tree, while somewhat more labor intensive to care for, may be planted in your yard after its holiday use, and enjoyed for years to come. You must do some planning before you take the tree home but it is well worth while. 1) Determine what spot on your property affords the correct exposure (full sun) and space. Check a good source or the internet to determine how much space your particular species of tree will require when mature. 2) Dig the hole NOW before the ground freezes. Digging a frozen hole is no fun. Make the hole approximately 2 times the width of what you expect the container or root ball will be. This is important; and do not dig the hole any deeper than the height of the container or root ball. Fill the hole with leaves or mulch as insulation, and cover the hole and the pile of soil with a tarp and more leaves or mulch to avoid freezing. Throw away whatever sod was dug up as you do not want it included in the backfill.
Your live tree should be indoors as briefly as possible; place it at first (in a waterproof tub or container) in a garage or porch to allow it to acclimate to warmer temperatures. Water it lightly and frequently, or place ice cubes over the root ball to keep the moisture levels up. Spraying the tree with an antidessicant such as Wiltproof will help control moisture loss through the needles.
When the tree is ready for planting, roll it into the hole and orient it so that its best side faces your house or the street. If the hole is too deep, add soil into the bottom and compact it until it is the right depth. Remove as much of the burlap around the root ball as possible; if it is in a container, remove the container. If it is in a wire basket, cut off as much of the basket as you can. Then, begin to backfill with the soil you set aside. Water it thoroughly and slowly as you fill the hole; this will push out air pockets and saturate the sides of the hole as well as the back fill.
It is not necessary to stake or guy the tree. Cover the area – to the drip-line- with 2-3” of double-shredded, hardwood bark mulch, keeping the mulch 2” away from the trunk. Water your Christmas tree every day for a week, twice the second week, and then once a week until the ground freezes and your hose becomes useless.
