Landscaping With Cedar Trees

Cedar trees bring year-round structure to landscapes through their evergreen foliage and natural resistance to decay. When you start landscaping with cedar trees, you are choosing a plant that offers privacy, fragrance, and a long lifespan. These trees are not just for large estates; they work in suburban yards too if you pick the right variety.

Before you dig a hole, you need to understand that “cedar” is a broad term. True cedars (like Cedrus) and false cedars (like Eastern Redcedar) have different needs. This guide will help you place them correctly so they thrive for decades.

Why Choose Cedar For Your Yard

Cedars are tough. They handle drought, poor soil, and cold winters better than most ornamental trees. They also act as a natural windbreak, which can lower your heating bills in winter.

Here is what makes them stand out:

Evergreen color: They stay green when other plants go dormant.
Low maintenance: Once established, they need little water or fertilizer.
Wildlife value: Birds nest in them and eat the berries (on female trees).
Wood quality: The wood is naturally rot-resistant, so fallen branches make great mulch.

You also get a natural screen. If you have a nosy neighbor or an ugly fence, a row of cedars solves that problem quietly. They grow dense enough to block sound and dust from the road.

Now we get to the core strategy. Landscaping with cedar trees is not about planting one tree in the middle of a lawn. It is about creating layers and using the tree’s shape to anchor your design.

Start by measuring your space. A single cedar can spread 15 to 25 feet wide. If you plant them too close to a house or sidewalk, you will fight the branches for years. Give them room to grow naturally, or plan to prune them every spring.

Choosing The Right Cedar Variety

Not all cedars are created equal. Your local climate and soil type will decide which one survives.

Eastern Redcedar: Actually a juniper. Tolerates heat, cold, and alkaline soil. Great for the Midwest and East Coast.
Deodar Cedar: Soft, drooping branches. Best for warm climates (zones 7-9). Needs good drainage.
Blue Atlas Cedar: Stunning blue-silver color. Slow growing but huge. Needs space.
White Cedar (Arborvitae): Not a true cedar but often sold as one. Perfect for tight hedges and wet soil.

Check your USDA hardiness zone before buying. A Blue Atlas will die in Minnesota, and an Eastern Redcedar might struggle in Florida’s humidity. Ask your local nursery what grows well nearby.

Spacing And Placement Rules

Spacing is where most people mess up. They plant small trees two feet apart, thinking they will form a hedge. Ten years later, the trees are fighting for light and dropping branches.

For a privacy screen: Space trees 6-8 feet apart. They will grow together but still have room.
For a specimen tree: Give it 20-30 feet of clearance from other large plants.
From your house: Keep cedars at least 15 feet from the foundation. Roots are shallow but branches can scrape siding.
From driveways: Plant at least 10 feet back. Falling needles can stain concrete.

Also, check the sun. Cedars love full sun (6+ hours). If you plant them in shade, they get thin and leggy. They will not fill out properly.

How To Plant A Cedar Tree Correctly

Planting is not hard, but it is specific. Follow these steps and your tree will establish fast.

Step-By-Step Planting Guide

Dig the hole: Make it twice as wide as the root ball but no deeper. The top of the root ball should sit slightly above ground level.
Check the root ball: If the roots are circling the pot, gently tease them apart. If they are a solid mass, cut four vertical slits with a knife.
Set the tree: Place it in the hole. Make sure it is straight. Have a helper look from two angles.
Backfill: Use the native soil you dug out. Do not add compost or potting mix. Cedars prefer lean soil.
Water deeply: Fill the hole with water after backfilling. Let it soak in. Then water again.
Mulch: Add 2-3 inches of wood chips around the base. Keep mulch 3 inches away from the trunk.

Do not stake the tree unless it is in a very windy spot. Cedars that move slightly in the wind grow stronger trunks. Staking makes them weak.

Watering Schedule For New Trees

The first year is critical. A young cedar has a small root system and dries out fast.

First month: Water every 2-3 days, deeply.
Months 2-6: Water once a week if no rain.
After one year: Water only during extended droughts.

Overwatering is worse than underwatering. Cedars hate soggy roots. If the soil is clay and holds water, plant on a slight mound to improve drainage.

Companion Plants For Cedar Landscapes

Cedars create acidic soil under their canopy as needles drop. Not everything grows well there. But you have options.

Groundcovers That Thrive Under Cedars

Vinca minor: Evergreen, blue flowers in spring. Tolerates shade and dry soil.
Pachysandra: Forms a dense green carpet. Very tough.
Wild ginger: Native, heart-shaped leaves. Loves the cool shade.

These plants will not compete with the cedar for water. They actually help keep the soil moist and cool.

Shrubs And Perennials To Pair

For texture contrast, plant things with different leaf shapes. Ferns look great at the base of a cedar. Hostas work too, but they need more water.

If you want color, add spring bulbs like daffodils. They bloom before the cedar leafs out (if it is deciduous) or just use the bright green of the cedar as a backdrop for flowering shrubs like azaleas.

Avoid planting grass right up to the trunk. Grass steals water and nutrients. Keep a mulched ring around the tree instead.

Pruning And Maintenance Tips

Cedars do not need heavy pruning. In fact, you can ruin their shape by cutting into old wood. They do not regrow from bare branches.

When To Prune

Late winter: Remove dead or broken branches.
Early summer: Lightly trim new growth to shape the tree.
Never in fall: Pruning stimulates new growth that will die in winter.

If you want a formal hedge, shear the new growth (the soft tips) in June. Do not cut back into the brown, woody interior. That will leave a permanent bare spot.

Dealing With Common Problems

Cedars are hardy, but they have a few issues you should watch for.

Bagworms: Brown, cone-like sacks hanging from branches. Pick them off and destroy them in winter.
Spider mites: Cause yellowing needles. Spray with a strong jet of water.
Winter burn: Brown tips in spring. This happens when roots are frozen and wind dries the needles. Plant in a protected spot or wrap in burlap.

Most problems come from stress. A healthy cedar fights off pests. Keep it watered in dry spells and it will be fine.

Design Ideas Using Cedars

Now for the fun part. How do you actually use cedars to make your yard look professional?

Creating A Living Fence

This is the most common use. Plant a row of cedars along your property line. It is cheaper than a wood fence and looks better.

Use a single variety for uniformity. Mixing types creates a messy look. Choose a columnar variety like ‘Taylor’ or ‘Emerald Green’ for narrow spaces.

Using Cedars As A Backdrop

Plant a tall cedar behind a flower bed. The dark green needles make bright flowers like roses or daylilies pop. It also gives the bed a sense of enclosure.

This works well in small yards. The cedar draws the eye upward, making the space feel larger.

Specimen Planting

If you have a large open lawn, plant one cedar by itself. Let it grow into its natural shape. A Blue Atlas cedar with its weeping branches is a showstopper.

Underneath, add a bench or a small stone path. This creates a quiet seating area that feels established and calm.

Frequently Asked Questions

How fast do cedar trees grow?
It depends on the variety. Eastern Redcedar grows 1-2 feet per year. Deodar can grow 2-3 feet per year. Dwarf varieties are much slower.

Do cedar trees have invasive roots?
No. Cedar roots are mostly shallow and fibrous. They do not crack foundations or sidewalks like willow or poplar trees. However, they do spread wide, so keep them away from septic fields.

Can I plant cedars near a septic tank?
It is not recommended. The roots will seek out the moisture and nutrients in the drain field. Plant at least 30 feet away from any septic system.

Why is my cedar turning brown inside?
That is normal. Cedars shed old inner needles in the fall. As long as the outer tips are green, the tree is healthy. If the outer needles are brown, check for pests or drought stress.

What is the best time of year to plant cedars?
Early fall is ideal. The soil is warm, and the cooler air reduces transplant shock. Spring is the second best option. Avoid planting in midsummer heat.

Final Thoughts On Cedar Landscaping

Cedars are a long-term investment. They take a few years to establish, but once they do, they are almost indestructible. They give you privacy, beauty, and a sense of permanence that few other trees can match.

Start with a plan. Measure your space, pick the right variety, and plant with care. In five years, you will have a landscape that looks like it has been there for fifty.

Remember to water deeply for the first year and prune lightly. Avoid the temptation to over-decorate the base with too many plants. Let the cedar be the star.

If you are ready to start, visit a local nursery and look at the cedars in person. Feel the texture of the needles. Smell the wood. Choose a healthy tree with a straight trunk and vibrant color. Your yard will thank you.

One last tip: take a photo of your yard before you plant. In ten years, you will look back and be amazed at how much that small tree has transformed your outdoor space. The patience pays off.

So grab a shovel, mark your spots, and get planting. Landscaping with cedar trees is one of the smartest choices you can make for your property. It adds value, shade, and peace of mind for decades to come.
