Why Remove Fir Cones?

Many tree professionals and Christmas tree buyers are not aware of how important it is to remove cones from fir trees.

Species such as Fraser fir can begin cone production only five or six years after planting, when trees are about six feet tall. Usually, cones develop when trees are seven to ten feet tall.

Fir cones grow vertically in the top portion of a tree, and can be about three inches long by the end of the summer. There can be hundreds of cones present. In 2015, we found one large tree with over 900 cones! Photo 1 shows a six-foot tall Fraser with developing cones.

There are two main problems relating to cone production for Christmas tree growers. Biologically, a tremendous amount of energy goes into cone development, and accordingly, tree growth is lessened, particularly for sides and tree tops. Christmas tree growers want maximum new growth to help develop tree shape and density. These fir cones are a detriment.

The other concern is that fir cones disintegrate in the fall; if they are not removed, large holes or gaps are left where the cones were growing. This degrades Christmas trees by creating big openings that are not desirable – see Photo 2, a Fraser that did not have cones removed in 2017.

Cone removals require field workers to visit every tree, typically in late May, and hand pick every cone; you can imagine what this might cost. This is a significant part of our annual budget.

To summarize reasons to remove cones:

Promotes increased side and top tree growth
Eliminates unsightly gaps in Christmas tree tops
Results in dense, high-quality trees that are appreciated by Christmas tree purchasers
