How to Preserve True Fir Cones


True fir trees are a type of evergreen conifer that live in areas all over the United States, from zones 4 to 7. Like pine trees and spruces, true fir trees have cones that function as reproductive organs. True fir cones are deciduous, so in the fall the fir cones shed their scales. If you want to preserve true fir cones for craft projects, you have to do so before their scales fall off.

Step 1

Pick the true fir cones in the mid- to late summer as they are fully formed. Use a ladder to reach any cones high on the tree. To pick the cones, simply twist them until they come off of the branches.

Step 2

Wipe any debris or insects off of the true fir cones.

Step 3

Place the cones on a sheet of aluminum foil on a cookie sheet and place them in a 200-degree oven for 30 minutes.

Step 4

Remove the true fir cones from the oven and allow them to dry for two to three days.

Step 5

Spray the cones with clear acrylic spray, one coat per cone, and allow them to dry.
