You can prune a whipcord cedar to keep it compact, remove dead growth, and encourage that fun, twisted texture it’s famous for.
If you’ve been wondering how to prune a whipcord cedar without ruining its unique look, you’re in the right place.
This guide will walk you through the best times to prune, the right tools, and the exact cuts to make.
Let’s dig into the details so your whipcord cedar stays healthy and stunning.
Why Pruning a Whipcord Cedar Is Important
Pruning a whipcord cedar isn’t just about making it look neat.
It’s about keeping the plant vigorous and preventing problems before they start.
Whipcord cedars, also known as *Thuja plicata* ‘Whipcord’, have distinctive drooping, rope-like foliage that can become dense and unruly over time.
When you prune a whipcord cedar regularly, you open up the center to light and air.
This reduces the risk of fungal diseases and keeps the foliage from turning brown on the inside.
Plus, a well-pruned whipcord cedar holds its sculptural shape much better in your landscape.
So, learning how to prune a whipcord cedar properly is a key skill for any gardener.
1. Pruning a Whipcord Cedar Keeps It Compact
If left alone, a whipcord cedar can spread out quite a bit, reaching up to four or five feet wide in some cases.
By pruning, you control the spread and keep it fitting perfectly in its spot.
You don’t need to be aggressive, just a light trim each year makes a huge difference.
2. Pruning a Whipcord Cedar Removes Dead or Damaged Growth
Winter can be rough on these evergreens, especially in colder zones.
Dead, brown, or brittle strands are common after harsh weather.
When you prune a whipcord cedar, you cut these off to make way for fresh green growth.
This also prevents pests from setting up camp in decaying foliage.
3. Pruning a Whipcord Cedar Boosts Airflow
The dense, cord-like foliage can trap moisture, which is a recipe for mold.
Thinning out some of the interior strands lets air circulate freely.
This simple step when you prune a whipcord cedar goes a long way in keeping it healthy.
When to Prune a Whipcord Cedar
Timing is everything when you prune a whipcord cedar.
The best time to prune a whipcord cedar is in late winter or early spring, just before new growth begins.
Pruning during this dormant period minimizes stress on the plant.
It also gives you a clear view of the plant’s structure without all the new foliage in the way.
You can also do a light touch-up in mid-summer if needed, but avoid heavy pruning in the fall.
Pruning late in the season encourages tender new growth that won’t harden off before frost.
So, mark your calendar for late February or March.
1. Prune a Whipcord Cedar in Late Winter
This is your main pruning window.
The plant is still dormant, so it won’t bleed sap or struggle to recover.
You’ll be able to see the structure clearly and make decisive cuts.
2. Prune a Whipcord Cedar Lightly in Summer
If a few strands are sticking out and ruining the look, feel free to trim them in June or July.
Just don’t go overboard.
A light trim here keeps the shape tidy without stimulating too much late growth.
3. Avoid Pruning a Whipcord Cedar in Fall
Fall pruning is a big no-no.
It forces the plant to push out new shoots that are vulnerable to winter burn.
Instead, let it go dormant naturally.
You can always clean up any damage in late winter.
How to Prune a Whipcord Cedar Step-by-Step
Now, let’s talk about the actual technique.
How to prune a whipcord cedar is simpler than you might think.
You don’t need fancy tools, just a clean pair of sharp bypass pruners or hedge shears.
Before you start, ensure your blades are sterilized with rubbing alcohol to prevent spreading disease.
1. Start by Removing Dead Wood
The first step when you prune a whipcord cedar is to identify and remove dead, brown, or damaged strands.
Cut these right back to the base of the plant or to a healthy lateral branch.
It’s okay if it looks a bit bare after this, the new growth will fill in quickly.
2. Thin Out the Interior
Next, reach into the plant and thin out some of the oldest, thickest strands.
This is crucial when you prune a whipcord cedar for airflow.
Remove about 10-15% of the interior growth, focusing on crossing or tangled branches.
This opens up the center and lets light reach the heart of the plant.
3. Shape the Outer Foliage
Finally, shape the outside of the plant.
Use your shears to lightly trim the tips of the whipcord strands to create a uniform, rounded shape.
Don’t cut into the woody base of the branches, as they won’t regrow from bare wood.
Always leave some green foliage on each branch you trim.
Remember, you can always prune a whipcord cedar again next year if it gets too big.
Tools You’ll Need to Prune a Whipcord Cedar
– Bypass pruners for individual strands.
– Hedge shears for shaping the overall silhouette.
– Rubbing alcohol for sterilizing your tools.
– Gardening gloves to protect your hands from the rough foliage.
– A tarp to catch the clippings for easy cleanup.
Common Mistakes to Avoid When You Prune a Whipcord Cedar
It’s easy to make mistakes if you’re new to this.
Let’s look at the most common pitfalls so you can avoid them.
1. Cutting Too Far Back
One of the worst things you can do is cut into the old, woody growth.
Whipcord cedars do not sprout new growth from bare wood.
If you prune a whipcord cedar back too hard, you’ll be left with permanent bare spots.
2. Pruning at the Wrong Time
We covered this, but it’s worth repeating.
Prune a whipcord cedar in late winter or early summer.
Avoid fall, as it leads to winter damage.
3. Using Dull Tools
Dull blades tear the foliage instead of cutting it cleanly.
This leaves jagged edges that brown and look unsightly.
Always sharpen your tools before you prune a whipcord cedar.
