How to Dry an Arborvitae

The arborvitae (Thuja occidentalis), or eastern white cedar, is a common evergreen tree found throughout Canada and the northeastern United States. Though it is rather ordinary in appearance, arborvitae boughs are covered in shiny, green, scalelike leaves. The fragrant, flat fans of foliage add a festive touch to holiday decorations and homemade potpourri. While arborvitae branches can be gathered and left to air dry, preserving the boughs in glycerin is preferable as the liquid readily takes the place of the plant's natural fluids, reducing leaf drop and creating branches that remain soft and pliable for years.

Instructions

    • 1

      Remove arborvitae branches up to 12 inches in length with a small knife, holding the blade at a slight angle. Choose healthy, flexible stems filled with fragrant, bright green foliage.

    • 2

      Cut the base of each branch lengthwise, creating a slit that is 1 to 4 inches long.

    • 3

      Place the cut stems in a vase filled with tepid water and leave them overnight. This will ensure the foliage is adequately hydrated prior to starting the preservation process.

    • 4

      Pour 1 cup of glycerin into a large bowl. Add 2 cups of boiling water and stir until the glycerin is dissolved. Set the mixture aside and allow it to cool.

    • 5

      Remove the arborvitae stems from the vase and drain the water. Refill the vase with glycerin solution.

    • 6

      Arrange the stems in the vase so the foliage does not touch, then place the vase in a cool, dark location.

    • 7

      Check the stems each day, refilling the vase with ordinary water, as needed. As the glycerin makes its way through the plant's vascular system, the affected foliage will fade to pale green or gold. When the new color reaches the tip of a branch, remove it from the glycerin solution.

    • 8

      Pat the stems with a soft, dry cloth and place them in a rigid container with an airtight lid, or put them to immediate use in floral arrangements, centerpieces or homemade potpourris.
