Understanding How Far Apart to Plant Arborvitae Trees for Maximum Health
When you start a landscaping project, it is tempting to pack trees closely together for an instant screen. However, nature requires room to breathe and space for roots to expand without competing for limited nutrients. If you plant too close, the lower branches will eventually die off due to a lack of sunlight, leaving you with a “leggy” look.
Determining how far apart to plant arborvitae trees depends on your primary goal: are you looking for a dense privacy hedge or a series of individual specimen trees? For a solid wall, you generally measure from the center of one trunk to the center of the next. This ensures that as the trees mature, their branches overlap just enough to create a seamless barrier.
Proper spacing also facilitates airflow, which is the best defense against needle blight and other fungal issues. In humid environments or areas with heavy rainfall, tight spacing traps moisture. Giving your trees the recommended gap allows the wind to dry the foliage, keeping the entire system healthy and vibrant year-round.
Spacing Requirements for Popular Arborvitae Varieties
Not all arborvitaes are created equal, and their growth habits vary significantly. A “Green Giant” will eventually tower over a small cabin, while an “Emerald Green” stays relatively slender and manageable. You must match your spacing to the specific genetic potential of the cultivar you have selected for your land.
Emerald Green Arborvitae (Thuja occidentalis ‘Smaragd’)
This is the most common choice for residential privacy screens because of its bright green color and narrow, pyramidal shape. It typically grows to about 12-15 feet tall and 3-4 feet wide. For a dense, continuous hedge, you should space these 2 to 3 feet apart on center.
If you prefer the trees to maintain their individual “teardrop” shapes, increase that distance to 4 or 5 feet. This variety is perfect for smaller homesteads where space is at a premium. It grows at a moderate pace, making it easier to maintain with standard pruning shears.
Green Giant Arborvitae (Thuja standishii x plicata)
If you have a large property or need a massive windbreak, the Green Giant is the undisputed king. These trees can grow up to 3 feet per year, eventually reaching heights of 40-60 feet. Because of their massive spread, you should space them 5 to 10 feet apart.
For a truly impenetrable “fortress” wall on a large acreage, many experts recommend a staggered planting pattern. Plant two rows, with the trees in the second row positioned behind the gaps of the first row. Space the rows about 6-8 feet apart to give the roots enough volume to anchor the trees against high winds.
American Pillar Arborvitae
The American Pillar is a newer favorite for those who need height but have very little lateral space. It grows very tall but stays extremely narrow, often only 2-3 feet wide. For a tight screen with this variety, space them 2 feet apart on center.
This variety is excellent for lining long driveways or creating a “green wall” right against a fence line. It provides the same privacy as a Green Giant but without the massive footprint. It is a smart choice for modern homesteaders working with narrow lot lines.
Key Factors That Influence Your Spacing Decisions
While the variety of the tree is the primary guide, environmental factors on your specific site might require you to adjust your plan. Before you start digging, take a look at your soil, sun exposure, and local climate. These elements dictate how fast and wide your trees will grow. Soil Quality and Nutrients: In rich, loamy soil, arborvitaes will reach their maximum width much faster than in compacted clay or sandy soil. If your soil is poor, you might be tempted to plant closer together to compensate for slower growth. Instead, it is better to amend the soil with organic compost and stick to the recommended spacing. Sunlight Availability: Arborvitaes love full sun, which encourages thick, dense foliage from top to bottom. If you are planting in partial shade, the trees will grow more slowly and may be “thinner.” In shady spots, you might want to tighten the spacing by 6 inches to ensure the screen closes up properly.
Local Wind Conditions: For those living in open plains or high-altitude areas, wind is a major factor. If you are planting a windbreak, spacing is a safety-first consideration. Trees planted too far apart won’t break the wind effectively, while those planted too close might suffer from “wind throw” if their root systems are restricted and shallow.
Step-by-Step Guide to Planting Your New Hedge
Once you have decided how far apart to plant arborvitae trees, it is time to get your hands in the dirt. Proper installation is the only way to ensure your investment survives the first winter. Follow these steps to give your trees the best start possible.
- Mark Your Line: Use a long piece of string and two stakes to create a straight line. Measure out your chosen spacing (e.g., 3 feet) and mark each spot with landscaping spray paint or a small flag.
- Dig the Right Hole: Dig a hole that is twice as wide as the root ball but no deeper. Planting too deep is a common mistake that leads to trunk rot. The top of the root ball should be level with or slightly above the soil surface.
- Prepare the Roots: If the tree is “root-bound” (roots circling the inside of the pot), gently tease them outward. This encourages the roots to grow into the surrounding soil rather than continuing to circle the trunk.
- Backfill and Water: Fill the hole with the original soil, tamping it down lightly to remove air pockets. Immediately give each tree a deep soak. This settles the soil and reduces transplant shock.
Using a transplant fertilizer or a root stimulant during this phase can help the trees establish themselves before the first frost. Always check your local weather forecast to ensure you have a few days of mild weather after planting. Avoid planting during extreme heatwaves or just before a hard freeze.
Essential Tools for Your Planting Project
Having the right gear makes the job faster and reduces physical strain. If you are planting dozens of trees for a large privacy screen, consider renting a power auger. This tool will save your back and ensure every hole is a consistent depth.
- Sharpened Spade: A high-quality steel shovel is essential for cutting through sod and heavy clay.
- Tape Measure: Don’t eyeball it; precision matters for a professional-looking hedge.
- Soaker Hose: These are perfect for new hedges, as they deliver water directly to the roots without wasting it through evaporation.
- Mulch: Use cedar or hemlock mulch to retain moisture and suppress weeds around the base of your trees.
- Work Gloves: Protect your hands from the abrasive foliage and blisters while digging.
For homesteaders working on rocky terrain, a pickaxe or a digging bar may also be necessary. Always call your local utility company to mark underground lines before you start any major digging project. Safety should always be your top priority when modifying your land.
Common Mistakes to Avoid When Spacing Your Trees
Even experienced gardeners can make errors when calculating how far apart to plant arborvitae trees. One of the biggest pitfalls is ignoring the “mature width” listed on the plant tag. That tiny sapling in the 3-gallon pot will eventually be 4 or 10 feet wide.
Another mistake is planting too close to existing structures like fences or sheds. If you plant an arborvitae right against a wooden fence, the lack of light and airflow on that side will cause the branches to die. Always leave at least 2-3 feet of space between the center of the tree and any permanent structure.
Finally, avoid “over-mulching.” While mulch is beneficial, piling it up against the trunk (the “mulch volcano”) traps moisture against the bark. This leads to rot and provides a hiding spot for rodents that might chew on the bark during the winter. Keep the mulch a few inches away from the base of the trunk.
Maintenance for a Long-Lasting Living Fence
Your job isn’t done once the trees are in the ground. The first two years are critical for “establishment.” During this time, the trees are focusing all their energy on building a robust root system. Consistent watering is the most important task during this phase.
In the heat of summer, your arborvitaes may need a deep watering twice a week. If the needles start to turn a dull grey-green or brown, they are likely thirsty. However, be careful not to overwater, as arborvitaes do not like “wet feet.” Well-draining soil is a must for long-term health.
Pruning is also vital if you want a formal look. You can trim the tops and sides of the trees in early spring or late summer. Avoid heavy pruning in the late fall, as new growth triggered by the trim may not have time to harden off before winter. Use sharp, clean tools to prevent the spread of disease.
The Benefits of Arborvitae for Homesteaders and Survivalists
Beyond simple aesthetics, these trees offer practical benefits for those pursuing a self-sufficient lifestyle. A thick row of arborvitae acts as a natural sound barrier, which is invaluable if your off-grid retreat is near a noisy road. They also provide excellent cover for local songbirds, which help control insect populations in your garden.
In survival scenarios, a dense hedge serves as a visual screen, keeping your activities and resources out of sight from the road. The thick foliage also acts as a thermal buffer, potentially reducing heating costs for your home by blocking cold winter winds. They are a multi-purpose addition to any resilient landscape.
Furthermore, arborvitaes are generally deer-resistant, though not “deer-proof.” If you live in an area with high deer pressure, the Green Giant variety is your best bet, as it is much less palatable to wildlife than the Emerald Green. Protecting your investment with a temporary snow fence or repellent spray during the first few winters is a wise move.
Frequently Asked Questions About How Far Apart to Plant Arborvitae Trees
How long does it take for arborvitae to create a full privacy screen?
Depending on the variety and the starting size, it usually takes 3 to 5 years for the branches to touch and create a solid wall. Green Giants grow much faster than Emerald Greens and will fill in the gaps more quickly.
Can I plant arborvitae in the shade?
Arborvitaes prefer full sun (at least 6 hours a day). While they can survive in partial shade, they will grow much slower and the foliage will be less dense. If you must plant in shade, ensure they have excellent drainage to prevent root rot.
What is the best time of year to plant arborvitae?
Spring and fall are the ideal seasons. Planting in the spring gives the trees a full growing season to establish roots. Fall planting is also successful as long as you do it at least 6 weeks before the ground freezes, allowing the roots to settle in the cool, moist soil.
Should I use fertilizer when I plant?
It is best to wait until the following spring to use a high-nitrogen fertilizer. When planting, focus on soil amendments like compost and perhaps a root-stimulating hormone. You want the tree to focus on root growth initially, not rapid top growth.
How do I know if I have spaced them too far apart?
If after 5 or 6 years you still see significant gaps between the trees, they may have been spaced too far. You can sometimes encourage wider growth by lightly pruning the tops (leading to more lateral growth), but it is difficult to fix poor spacing after the fact.
Final Thoughts on Planning Your Outdoor Space
Taking the time to measure and plan how far apart to plant arborvitae trees is an investment in the future of your property. These “trees of life” provide more than just a border; they offer peace, security, and a connection to the natural world. By choosing the right variety and giving it the space it needs, you ensure your homestead remains a private sanctuary for years to come.
Remember that gardening and homesteading are skills that require patience. Don’t be discouraged if your saplings look small at first. With the right spacing, water, and care, they will soon transform into the towering green wall you envisioned. Always keep your tools sharp, your soil healthy, and your eyes on the long-term growth of your land.
Whether you are building a prepper pantry or just looking for a bit of backyard solitude, your outdoor journey starts with a single well-placed tree. Stay safe, stay prepared, and enjoy the process of growing your own living fortress!
