Step-by-Step Guide to Pruning Overgrown Boxwoods

Now that you know the basics, here’s how to actually do the job.
 

1. Start with the Three D’s

Always begin by removing dead, damaged, or diseased branches.
 
This cleanup helps you see the plant’s true structure before you cut back overgrown boxwoods further.
 
It also improves airflow, which reduces the risk of fungal problems.
 

2. Thin Out the Center

Overgrown boxwoods often have a dense, tangled interior.
 
To cut way back overgrown boxwoods, selectively remove some inner branches to open up light and air.
 
Thinning prevents the plant from becoming a shelter for pests and promotes even regrowth.
 
Take out no more than one-third of the oldest branches at a time.
 

3. Reduce the Height and Width

This is the main event when you cut back overgrown boxwoods.
 
Use loppers to shorten the longest branches by about one-third to one-half.
 
If you need to cut way back overgrown boxwoods drastically, cut some branches down to just a few inches above the ground.
 
Leave a few lower side branches on each main stem to help the plant recover faster.
 

4. Shape Gradually

Don’t try to create a perfect shape all at once when you cut back overgrown boxwoods.
 
Aim for a natural, slightly tapered form that lets sunlight reach the base.
 
Cutting way back overgrown boxwoods into a tight ball can leave the bottom bare.
 
Instead, work in layers, stepping back often to check your progress.

1. Cutting Into Old Wood Without Leaves

Boxwoods don’t sprout well from bare, leafless stems.
 
If you cut way back overgrown boxwoods to a part of the branch that has no green growth, it may stay dead.
 
Always prune back to a branch fork or to a spot where a few leaves remain.
 

2. Removing Too Much Foliage at Once

Taking off more than one-third of the greenery in a single season can shock the plant.
 
When you cut back overgrown boxwoods heavily, split the work over two or three years for safety.
 
Cutting way back overgrown boxwoods too fast leaves the plant weak and vulnerable to sun scald.
 

3. Neglecting Aftercare

Water deeply during dry spells to support new growth.
 
Apply a layer of mulch around the base (but not touching the trunk) to keep roots cool.
