Ideal Cutting Size: 4-5 Inches, Mostly Green And Pliable

The size and condition of the arborvitae cuttings are crucial for successful propagation. Optimal cutting size is around 4 to 5 inches. It is important to choose stem tips that are mostly green, pliable, and healthy. Avoid using woody or overly mature stems, as they are less likely to develop roots and establish successfully.

How to select suitable cuttings?

When selecting cuttings, it is important to inspect the stems for signs of disease, pests, or damage. Healthy, disease-free stems with vigorous growth are more likely to root successfully. Additionally, make sure that the cutting has at least a few sets of leaves to support photosynthesis and provide essential nutrients during the rooting process.

Preparing Cuttings: Carefully Strip Leaves From The Base Of The Cutting

Before planting the cuttings, it is important to carefully strip the leaves from the base of the stem. This step is crucial as it helps redirect the plant’s energy towards root development instead of supporting leaf growth. It is advised to remove the bottom 1-2 inches of leaves and nodes, while leaving the top foliage intact. By doing so, a good balance can be achieved between leaf surface area for photosynthesis and energy allocation towards root development.

  • Strip the leaves from the base of the stem
  • Remove the bottom 1-2 inches of leaves and nodes
  • Leave the top foliage intact for a good balance

“This step helps divert the plant’s energy towards root development rather than supporting leaf growth.”
