How Far Apart To Plant Cedar Trees? Mastering Spacing For Optimal Growth


How Far Apart To Plant Cedar Trees? Mastering Spacing For Optimal Growth

Cedar trees are a dense, slow-growing species that can benefit from proper spacing to promote healthy growth and prevent overcrowding. As a general rule, it’s recommended to plant cedar trees at least 10-15 feet (3-4.5 meters) apart, although this distance may vary depending on the specific cultivar or desired density of the stand. Proper spacing allows for good air circulation, reduces competition for resources, and makes it easier to prune and maintain the trees.


As a seasoned arborist, I’ve had the privilege of watching cedar trees thrive (or struggle) in various environments.

And let me tell you – proper spacing is crucial for these magnificent trees to reach their full potential.

When planted too close together, cedar trees can become a tangled mess, suffocating under their own dense foliage and struggling to access the sunlight they need to photosynthesize.

But when given the breathing room they deserve, these stately evergreens can grow strong, statuesque, and remarkably resilient.

In this post, I’ll dive into the importance of spacing for cedar trees, sharing my expertise on how to create an optimal environment that allows your trees to flourish – and sharing some valuable lessons learned along the way.

Understanding Cedar Tree Growth Habits

As a tree enthusiast, I’m excited to dive into the world of cedar trees – specifically, how far apart to plant them for optimal growth.

But before we get to that, let’s start with the basics.

What do we mean by “optimal growth”?

For cedar trees, it means creating an environment where they can thrive, unfettered by overcrowding or lack of space.

So, just how big do cedar trees get?

Well, their mature size varies depending on the species.

For instance, the Eastern Red Cedar (Juniperus virginiana) can reach heights of 30 to 40 feet, with a spread of around 10 to 15 feet.

The Western Red Cedar (Thuja plicata), on the other hand, can grow up to 50 feet tall and 20 feet wide.

Now, you might be thinking, “What’s the big deal?

Just give them plenty of space, and they’ll be happy!” But it’s not that simple.

If you don’t provide enough room for your cedar trees to spread out, they can grow densely – a phenomenon known as “wall-to-wall” growth.

Wall-to-wall growth is exactly what it sounds like: the trees grow so close together that there’s little to no air circulation between them.

This lack of airflow creates an ideal environment for disease and pests to thrive.

In fact, studies have shown that when cedar trees are grown in dense conditions, they’re more susceptible to diseases like root rot and needle blight.

So, what’s the solution?

Simply put: give your cedar trees some elbow room!

The ideal spacing distance will depend on the specific species, but as a general rule of thumb, aim for:

  • 10 to 15 feet between Western Red Cedars
  • 5 to 7 feet between Eastern Red Cedars

Of course, these are just general guidelines.

If you’re planting multiple cedar trees together, make sure to consider factors like sunlight, soil quality, and wind direction.

Now that we’ve covered the basics of cedar tree growth habits, let’s take a look at some specific species and their unique characteristics:

  • Colorado Blue Spruce (Picea pungens): Known for its vibrant blue-gray foliage, this species can grow up to 50 feet tall with a spread of around 20 feet. Plant them 15 to 20 feet apart.
  • Northern White Cedar (Thuja occidentalis): With its aromatic leaves and ability to thrive in poor soil conditions, this species can reach heights of 30 feet or more. Give them 10 to 15 feet of space.
  • Atlas Cedar (Cedrus atlantica): Native to the Atlas Mountains, this species is prized for its distinctive cones and aromatic wood. It can grow up to 60 feet tall with a spread of around 20 feet. Plant them 15 to 20 feet apart.

By understanding the growth habits of cedar trees and providing them with the right amount of space, you’ll be well on your way to creating a thriving and healthy cedar tree garden.

Stay tuned for our next installment, where we’ll dive deeper into the world of cedar tree care and maintenance!

Benefits of Proper Spacing for Cedar Trees

When it comes to planting cedar trees, many people think that the more, the merrier.

But, believe it or not, cramming too many cedar trees together can actually do more harm than good.

That’s why proper spacing is crucial for these beautiful trees.

Improved Air Circulation and Reduced Risk of Disease

I mean, who doesn’t love a tree with a strong immune system?

Properly spaced cedar trees enjoy better air circulation, which means they’re less likely to develop diseases like root rot or fungal infections.

In fact, studies have shown that trees planted too close together are up to 30% more susceptible to disease (Source: “Tree Planting and Maintenance” by the Arbor Day Foundation).

By giving your cedar trees some breathing room, you’re giving them a better chance at staying healthy and thriving.

Increased Sunlight Penetration and Photosynthesis

Sunlight is like oxygen for plants – they can’t survive without it.

And when you plant cedar trees too close together, you’re blocking out valuable sunlight.

This can lead to stunted growth, yellowing leaves, and even reduced photosynthesis (the process by which plants turn sunlight into energy).

By spacing your cedar trees correctly, you’re allowing them to soak up all the sunlight they need to grow strong and healthy.

Easier Maintenance and Pruning

Let’s face it – maintaining a garden can be a real pain.

But when you plant cedar trees too close together, pruning becomes a nightmare!

You’ll spend hours hacking away at branches just to keep the trees from becoming tangled and overgrown.

By giving your cedar trees some space, you’ll make maintenance a breeze (and save yourself some serious time and effort).

Aesthetically Pleasing Appearance

Last but not least, proper spacing can actually enhance the visual appeal of your garden!

When cedar trees are planted too close together, they can create an impenetrable wall that blocks out views and makes it difficult to navigate.

By leaving enough space between each tree, you’ll create a visually appealing landscape that’s easy to enjoy.

So there you have it – the benefits of proper spacing for your cedar trees.

It might seem like common sense, but trust me, I’ve seen some seriously overcrowded gardens in my time!

By giving your cedar trees the space they need to grow and thrive, you’ll be rewarded with healthier, happier trees that will bring joy to your garden for years to come.

Factors to Consider When Determining Spacing for Cedar Trees

When it comes to planting cedar trees, many people wonder how far apart they should be.

It’s a great question!

The answer depends on several key factors that can impact the health and growth of your trees.

In this section, we’ll dive into the most important considerations when determining the perfect spacing for your cedar tree planting.

Climate and Soil Type

The first factor to consider is the climate and soil type in your area.

If you live in a hot and dry region, you may want to plant your cedar trees farther apart to ensure they have enough room to grow and receive adequate sunlight.

On the other hand, if you’re in a cool and moist climate, you can plant them closer together.

For example, let’s say you’re planting cedar trees in the arid desert southwest.

You’ll want to leave at least 15-20 feet between each tree to ensure they have enough space to grow and thrive in the hot sun.

On the other hand, if you’re planting in a cool and misty Pacific Northwest climate, you can plant them as close as 5-10 feet apart.

Mature Size of the Trees

Another crucial factor to consider is the mature size of your cedar trees.

Some species of cedar can grow quite large – up to 50 feet tall!

If you’re planting these types of trees, you’ll want to leave more space between them to accommodate their growth.

For instance, if you’re planting a species like the Eastern Red Cedar (Juniperus virginiana), which can grow up to 30-40 feet tall, you should leave at least 20-25 feet between each tree.

This will give them plenty of room to spread out and reach their full potential.

Desired Density or Openness of the Planting

The density or openness of your planting is another important factor to consider.

Do you want a dense hedge or an open, airy landscape?

This decision will impact how far apart you plant your cedar trees.

If you’re looking for a dense hedge, you’ll want to plant your trees closer together – typically 3-5 feet apart.

This will create a lush and verdant barrier that’s perfect for screening out unwanted views or creating a cozy atmosphere.

On the other hand, if you’re aiming for an open landscape with plenty of space between the trees, you can plant them farther apart – typically 10-20 feet apart.

This will create a more airy and spacious feel that’s ideal for highlighting the natural beauty of your landscape.

Pruning and Maintenance Needs

Finally, consider the pruning and maintenance needs of your cedar trees.

Some species require regular pruning to maintain their shape or promote healthy growth.

If you’re planting these types of trees, you’ll want to leave more space between them to make it easier to prune and maintain them.

For example, if you’re planting a species like the Western Red Cedar (Thuja plicata), which requires regular pruning to maintain its shape, you should leave at least 10-15 feet between each tree.

This will give you plenty of room to prune and maintain them without feeling crowded or overwhelmed.

Case Studies: Successful Cedar Tree Plantings

To illustrate these points, let’s take a look at some case studies of successful cedar tree plantings with varying spacings.

For example:

  • A homeowner in the Pacific Northwest planted Eastern Red Cedars 10 feet apart to create a lush and verdant hedge that provides year-round interest.
  • A landscape architect designed a public park with Western Red Cedars spaced 20-25 feet apart to create an open and airy atmosphere that showcases the natural beauty of the trees.
  • A nursery owner in the arid desert southwest planted Leyland Cypress (Cupressus x leylandii) – a fast-growing cedar species – 15-20 feet apart to ensure they had enough space to grow and thrive in the hot sun.

These case studies demonstrate how different spacings can create unique and beautiful landscapes that meet the needs of their owners.

By considering these factors and choosing the right spacing for your cedar tree planting, you can create a thriving and healthy landscape that brings joy and beauty to your life.

Final Thoughts

In this journey through the world of cedar tree spacing, I’ve learned that it’s not just about throwing a few trees in the ground and hoping for the best.

By understanding the unique growth habits of these majestic creatures, we can unlock their full potential and create a thriving ecosystem.

Proper spacing is key to ensuring optimal growth, reduced risk of disease, and an aesthetically pleasing appearance.

Whether you’re planting a small grove or a sprawling forest, it’s crucial to consider factors like climate, soil type, mature size, and desired density.

With the right approach, your cedar trees will thrive – and so will you.
