Choose your tree carefully — some of these beauties grow awfully big.
PLANTING A LIVING Christmas tree in the garden is a great way to commemorate a special holiday. If you want your tree to be long-lived, however, you’ve got to take steps to keep it from breaking dormancy in your home.
The first step is to gradually acclimate the tree to increased warmth by keeping it in an unheated garage for a couple of days before bringing it into the house. When you move it inside, place the tree in a watertight container, and surround the rootball with sawdust or mulch to hold moisture and to help keep the tree upright. Water enough to keep the rootball moist at all times, but don’t let it sit in water.
Locate your living Christmas tree in a bright spot, but away from heat sources such as a heater vent or TV, and decorate with non-heat-producing LED lights.
Set the thermostat below 70 degrees, and keep the tree inside for no longer than seven to 10 days.

During the years I directed grounds care at Seattle University, we planted a number of trees that had been displayed as living Christmas trees. I found that spruces and pines were the easiest to transplant and usually could make the transition from Christmas tree to landscape specimen with few problems.
Some of the true firs, on the other hand, were less likely to survive when planted into the garden after the holidays. If you want to use a noble, grand or white fir for your living Christmas tree, choose one grown for use as a…
