Question: My Christmas tree, a balsam fir, is producing fresh green shoots. Some are 6 inches (15 cm long) and I have to water it 3 times a day to keep it from drying out. How long can it live in water and what can I do with the new shoots?
Answer: The phenomenon you are experiencing is rare, but not unheard of. It sometimes happens that a cut conifer awakens from its winter dormancy and, if so, its buds will start to grow. As you’ve noticed, the tree will then be in full growth and so its watering needs will increase. And sometimes too, a cut fir tree can survive more than the usual two or three weeks: up to 72 days. Eventually, however, your tree will die, because a cut-off conifer with such a thick trunk simply does not have the capacity to produce roots. And a tree without roots is doomed.
The new shoots will die with the tree. Theoretically, you could remove them and use them as cuttings, but that’s not likely to be useful for you unless need several fir trees on your property. Generally, it’s just as quick (and less expensive) to start fir trees from seed as from cuttings.
It makes more sense to think of your cut Christmas tree as a temporary decoration and put it outside when you’re ready to end the festive season.
Second Life for a Christmas Tree
You don’t have to throw your fir tree away, however. You can easily install it outdoors as a winter decoration. (For example, in my garden we always use our old Christmas tree to hide the trash can.) Or as a winter shelter for birds.
As long as winter in your area is cold, any needle loss will soon stop and the tree will stay green for a very long time.
In spring, the needles that fall to the ground make a good mulch and you can also cut the branches and reduce them into mulch as well. Its trunk, now bare, can become a plant stake or be cut into sections as firewood.
Or maybe your municipality composts Christmas trees. If so, you can put it out so it can be carted away and recycled.
