How To Propagate Green Giant Arborvitae: A Detailed Guide

Green Giant Arborvitae is a popular evergreen tree that belongs to the cypress family. It is highly valued for its fast growth, attractive foliage, and natural resistance to pests and diseases. If you are looking for an easy way to multiply your Green Giant Arborvitae collection or create a new one from scratch, propagation is the answer. In this post, we will discuss how to propagate Green Giant Arborvitae using three methods: cuttings, layering, and seeds.


Propagation by cuttings involves taking a stem section from an existing arborvitae plant and planting it in moist soil until it develops roots. Here’s how to do it:

1. Choose a healthy branch that has no signs of damage or disease.
2. Cut off a few inches of the branch with sharp pruning shears.
3. Strip off any leaves on the lower half of the cutting.
4. Dip the bottom end of the cutting into rooting hormone powder (optional).
5. Place the cutting in moist potting soil.
6. Cover with plastic wrap or put inside a clear plastic bag to maintain humidity.
7. Keep out of direct sunlight but ensure there is plenty of light available
8.Water frequently just enough so that soil remains evenly moist throughout

The rooted cuttings can be transplanted outdoors after they have grown several inches tall.


Propagation by layering involves bending down a lower branch of an existing tree so that it touches or nearly touches the ground then covering part or all over this buried portion with soil.Once roots have formed,this new individual can be detached from parent plant.Here’s how to do it:

1.Choose low hanging branches as these are easier for layering
2.Select about 1 foot length branching which must not show any sign damage/disease
3.Carefully remove around 7 inch long leaves along nodes area without damaging them .
4.Bury around 2 inch of the stem into soil.
5.Keep layer moist and out of direct sunlight
6.Wait for new roots to form
7.Cut and detach from parent plant


Propagation by seed is usually limited to commercial growers as it takes a long time for these trees to mature. However, if you’re interested in trying this method, here’s what to do:

1.Soak seeds diluted with water
2.Sow thinly (around 3mm )in suitable seed compost under propagating cover or in your greenhouse .
3.Water consistently so that they are always lightly moist but don’t let them dry out.
4.Once grown at around 15cm tall ,re-pot them in individual pots
