How to Trim an Arborvitae Bush the Right Way

When you trim an arborvitae bush, follow these essential steps to ensure healthy growth.
 

1. Choose the Right Time to Trim Your Arborvitae Bush

Timing is crucial when you trim an arborvitae bush.
 
The best time to trim an arborvitae bush is in late spring or early summer after new growth appears.
 
Avoid trimming an arborvitae bush in late fall because cuts won’t heal before winter.
 
If you need a light shaping, trimming your arborvitae bush in early spring is also fine.
 

2. Use Sharp, Clean Tools to Trim an Arborvitae Bush

Sharp tools make trimming an arborvitae bush much cleaner and safer.
 
When you trim an arborvitae bush, use pruning shears or hedge trimmers that are sterilized.
 
Dirty tools can spread disease while you trim an arborvitae bush, so always disinfect blades.
 

3. Cut Less Than One-Third of the Foliage

A key rule when you trim an arborvitae bush is never to remove more than one-third of the green growth.
 
Trimming an arborvitae bush too heavily exposes brown interior wood that won’t regrow.
 
So when you trim an arborvitae bush, focus on the green tips and avoid cutting into old wood.
 

4. Shape Natural-Looking Lines

Arborvitae bushes look best with a slight taper, wider at the bottom and narrower at the top.
 
When you trim an arborvitae bush, follow the natural cone or pyramid shape.
 
This allows sunlight to reach the lower branches and keeps your arborvitae bush full.
 

Common Mistakes When Trimming an Arborvitae Bush

Even experienced gardeners can slip up when they trim an arborvitae bush.
 
Here are mistakes to avoid.
 

1. Cutting Into the Brown Center

Arborvitae branches do not regrow from leafless brown wood.
 
If you trim an arborvitae bush too deep, you’ll create permanent bare patches.
 
Always leave at least a bit of green foliage when trimming an arborvitae bush.
 

2. Trimming in Direct Sun or Heat

Trimming an arborvitae bush in hot sun can stress the plant.
 
Best practice is to trim an arborvitae bush in the early morning or overcast day.
 
This prevents the fresh cuts from drying out too fast.
 

3. Neglecting to Clean Up Debris

After you trim an arborvitae bush, remove all clippings from the ground.
 
Leftover debris can harbor pests and diseases near your arborvitae bush.

If your arborvitae bush is very tall or overgrown, trimming an arborvitae bush safely might require a professional.
 
Also, if you’re unsure how to trim an arborvitae bush that has storm damage, get help.
