If you’re planning to purchase a live Christmas Tree to plant in your yard later, do yourself a huge favor and dig the hole now. You’ll be glad you did, especially if the weather turns and freezes the ground solid. Keep the loose soil in a garage, barn, or protected from the elements so it will remain loose and dry.
You’re welcome!
Addendum
It’s probably best to only have that potted tree indoors for 3-4 days. Much longer would have it break dormancy and begin to bud. Too many new tender buds on that little tree could lead to disaster when moved outdoors and the temperature falls below freezing.
When you’re ready to plant your tree. Gradually acclimate it to the outdoors. Again, you want to avoid shocking it! One of the biggest shocks to plants going outdoors is light intensity. The second is wind. Plants that have been indoors are not used to wind which can cause them to dry up very quickly. Last is temperature. To avoid temperature shock, introduce your plant to the outdoors a few hours a day, then gradually increasing the time outside. After a week or two, your plants should be fully acclimated to the outdoors.
Last, if you can’t plant it right away, try to place the potted tree in a protected area. Potted plants don’t do well when left above ground in freezing temps.
