Top Privacy Tree Varieties for Southwestern Ontario

Creating a living fence requires selecting species that thrive in the local climate while providing dense, year-round foliage. When considering the best trees to plant for privacy in London & St. Thomas, Ontario, evergreens are typically the preferred choice because they do not drop their leaves in the winter, ensuring your property remains shielded from view all year long.

Here are the top screening trees recommended by professional arborists for Middlesex and Elgin counties:

• Eastern White Cedar (Thuja occidentalis): A native species to Ontario, the Eastern White Cedar is incredibly hardy and adapts well to various soil types. It grows quickly when properly watered and forms a thick, impenetrable hedge when planted in a row.

• Emerald Cedar (Thuja occidentalis 'Smaragd'): Known for its bright green foliage and narrow, pyramidal shape, the Emerald Cedar is perfect for tighter residential property lines where horizontal space is limited.

• White Spruce (Picea glauca): For larger residential lots or commercial properties needing a windbreak as well as privacy, the White Spruce is an excellent choice. It is highly resilient to local weather extremes and provides dense, wide-reaching branches.

• Columnar European Hornbeam (Carpinus betulus 'Fastigiata'): While deciduous, this tree retains its brown foliage through most of the winter. Its tight, upright growth habit makes it an elegant architectural choice for modern landscaping and narrow boundaries.

A successful privacy screen depends heavily on understanding the mature height and spread of these trees to prevent future overcrowding or encroachment on neighboring properties.

Why Hire an ISA-Certified Arborist for Tree Planting

Planting a tree might seem like a straightforward weekend DIY project, but establishing a long-lasting privacy hedge requires scientific knowledge and careful planning. Homeowners searching for an expert tree service near them should always look for ISA certification. This credential is the gold standard for professional arborists, ensuring that the team understands tree biology, soil science, and proper planting techniques.

Improper planting is one of the leading causes of tree mortality. If a root ball is buried too deeply, the tree can slowly suffocate. Conversely, if planted too shallow, the root system remains vulnerable to drought and strong winds. Additionally, planting large, fast-growing trees too close to foundations, underground utilities, or overhead power lines creates significant safety hazards and future liability for property owners.

Out on a Limb Tree Experts mitigates these risks through careful site assessment. By evaluating soil composition, drainage, and light exposure, an ISA-certified arborist ensures the right tree is planted in the right place, protecting your investment and your property.

The Tree Planting Process: What to Expect

When you hire a professional team for tree planting, the process is streamlined, efficient, and focused on the long-term health of the trees. It begins with a comprehensive site evaluation. An arborist will assess the specific microclimate of your yard, including how water moves across the property and how much direct sunlight the proposed planting area receives.

Next is the species selection phase. Based on the site assessment and your specific privacy goals, the arborist will recommend the most suitable varieties. Once the species are selected, the physical planting process begins.

Professionals will excavate the planting holes to the exact depth of the root ball and two to three times as wide, giving the roots ample room to establish. The tree is positioned, backfilled with appropriate native soil, and thoroughly watered to eliminate air pockets. Finally, a proper layer of organic mulch is applied to retain moisture and regulate soil temperature, taking care to keep the mulch away from the trunk to prevent rot. A professional service will also provide you with clear aftercare instructions, ensuring your new privacy screen thrives during its critical first year.

Thriving in London & St. Thomas Weather

The climate in Southwestern Ontario presents unique challenges and opportunities for landscaping. London and St. Thomas fall within hardiness zones 6a and 6b. This means the best trees to plant for privacy in London & St. Thomas, Ontario must be capable of surviving freezing winter temperatures, heavy ice storms, and hot, humid summers.

Furthermore, the region is known for frequent freeze-thaw cycles during the late winter and early spring, which can heave newly planted, shallow root systems. Local soil conditions also play a massive role; many areas in London and Middlesex County have heavy clay soils that retain water and drain poorly, while parts of St. Thomas and Elgin County may have sandier compositions. A local, experienced arborist understands these regional nuances. They will know exactly how to amend clay-heavy soil to improve drainage or how to select species that naturally tolerate “wet feet,” ensuring your privacy trees survive their first harsh Canadian winter and flourish for decades.

Frequently Asked Questions

What are the fastest-growing trees for privacy in Ontario?

Eastern White Cedars and hybrid poplars are among the fastest-growing trees for privacy screens in Ontario. With proper sunlight and watering, a healthy cedar can grow up to 1 to 2 feet per year once established. An arborist can help you balance fast growth with long-term structural stability.

How much space do I need to plant a row of privacy trees?

The required space depends entirely on the tree species. Emerald Cedars can be planted 2 to 3 feet apart for a tight hedge, while larger trees like White Spruce need 8 to 12 feet of spacing to accommodate their mature spread. Proper spacing prevents the trees from competing for nutrients and sunlight.

When is the best time of year to plant trees in London, Ontario?

The optimal times to plant trees in London and St. Thomas are early spring, just after the ground thaws, or early to mid-autumn. Planting during these cooler seasons allows the tree to focus its energy on root development without the stress of summer heat and drought.

Do I need a permit to plant or remove a tree in St. Thomas or London?

Tree planting generally does not require a permit, but you must ensure you are planting within your property lines and avoiding underground utilities by contacting Ontario One Call. Tree removal, however, is often subject to municipal tree protection bylaws, especially for trees over a certain diameter. Out on a Limb Tree Experts can help you navigate local regulations.

How often should I water my newly planted privacy trees?

Newly planted privacy trees require consistent watering, especially during their first growing season. You should water deeply once or twice a week, depending on rainfall, ensuring the soil remains moist but not waterlogged. Your arborist will provide a specific watering schedule tailored to your soil type and tree species.
