Preparing a commercial site for sod goes beyond surface work, it requires strategy, structure, and timing. Every layer beneath the turf influences how it performs above. Sodding Canada takes a comprehensive approach to ensure the ground is conditioned, leveled, and ready to support healthy, lasting growth. From soil testing to drainage planning, proper preparation reduces long-term maintenance, enhances appearance, and ensures the landscape delivers results from day one.
Key Takeaways
- Clear and grade the site thoroughly
- Conduct soil testing before installation
- Plan irrigation for consistency
- Choose the right sod for the space
- Sodding Canada handles end-to-end preparation
Why Commercial Sod Preparation Requires a Different Approach
Commercial landscapes are high-visibility, high-traffic areas. The expectations for appearance and performance are non-negotiable. But commercial sites also come with variables, underground utilities, soil compaction from machinery, and inconsistent sun exposure, which require careful planning.
A rushed sod job on a large commercial property often results in patchy growth, drainage problems, and early replacement. That’s why preparation is not just the first step; it’s the most important one.
At Sodding Canada, we approach each commercial project with site-specific strategy, industry expertise, and proven techniques.
1. Conduct a Site Assessment
The first step in preparing a commercial site for sod installation is evaluating the entire area. This step identifies potential challenges and allows you to develop a comprehensive plan.
- Assess Soil Conditions: Examine the soil’s type, texture, and overall quality. Determine if it’s sandy, loamy, or clay-heavy. Different sod types thrive in different soil conditions.
- Identify Drainage Patterns: Note low spots where water may collect and areas that may need regrading to prevent standing water.
- Examine Sunlight and Shade: Some sod varieties perform better in full sun, while others tolerate partial shade. Understanding sunlight patterns helps in choosing the appropriate grass type.
- Check for Construction Debris: Since commercial sites often undergo heavy construction, remove rocks, concrete chunks, metal, and other debris that may hinder sod establishment.
2. Perform Soil Testing
Soil testing is a critical step that should not be skipped. It provides detailed information on soil pH levels, nutrient content, and organic matter, key factors that affect sod growth.
- Why Test?: Knowing your soil’s pH and nutrient profile allows you to make informed decisions about fertilizers and amendments.
- When to Test?: Test at least 2–3 weeks before installation to allow time for soil amendment application and settling.
- How to Test?: Use a reliable soil testing kit or send samples to a local agricultural extension or laboratory. Tests will recommend pH correction agents (lime or sulfur) and fertilizers tailored to your specific site.
3. Clear and Grade the Site
Once the soil has been tested, clear the area of any remaining vegetation, debris, or existing turf. Proper grading is essential for both safety and the health of your sod.
- Kill Existing Vegetation: Use a non-selective herbicide (such as glyphosate) to remove weeds and old grass. Wait 7–10 days before proceeding.
- Remove Dead Vegetation: After herbicide treatment, use a sod cutter or tiller to remove the dead vegetation and loosen the top layer of soil.
- Grade for Drainage: Slope the soil away from buildings and sidewalks to prevent water from pooling. A gentle slope (1–2% grade) is typically sufficient.
- Eliminate High and Low Spots: Use a landscape rake, box blade, or skid steer to level the soil. Smooth surfaces allow even sod contact with the soil and improve rooting.
4. Amend the Soil
Based on your soil test results, add necessary amendments to improve soil structure, pH, and nutrient levels.
- Adjust pH: Apply lime if the soil is overly acidic. If too alkaline, use sulfur. Spread evenly and till into the top 4–6 inches of soil.
- Add Organic Matter: Incorporating compost or organic matter improves soil aeration and water retention, especially important in clay-heavy or sandy soils.
- Apply Fertilizer: Use a starter fertilizer rich in phosphorus to promote root development. Mix it into the topsoil evenly before sod is laid.
5. Ensure Proper Irrigation Infrastructure
An efficient irrigation system is vital on commercial properties, where large sod areas require consistent watering.
- Install Before Sod: Ensure irrigation systems are installed, tested, and fully operational before laying sod. Adjust sprinkler heads for full coverage.
- Check Water Pressure and Coverage: Uneven watering leads to patchy sod and increased weed pressure. Calibrate the system to provide 1 to 1.5 inches of water per week, distributed evenly.
- Smart Controllers: Consider installing smart irrigation controllers that adjust watering schedules based on weather and soil moisture, reducing water waste and improving sod health.
6. Final Soil Preparation
After grading and amending the soil, perform a final preparation to create the ideal bed for sod rooting.
- Rake and Smooth the Surface: Clear away rocks, roots, and clumps to create a smooth, even surface.
- Roll the Soil: A light rolling compacts the soil slightly, creating a firm base for sod contact. Prevent excessive compaction, as it can restrict root development.
- Moisten the Soil: Lightly water the soil a day before sod installation. It should be moist but not soggy, allowing sod roots to bond with the soil easily.
7. Plan the Sod Installation Strategically
Once the site is fully prepared, plan the sod installation with timing, logistics, and labor in mind.
- Schedule Delivery Wisely: Sod should be delivered the same day or the day before installation. Sod deteriorates quickly if not laid promptly.
- Lay Sod Promptly: Begin installation immediately upon delivery, preferably in the morning. Lay sod in staggered brick-like patterns to prevent seams from lining up.
- Use a Roller After Installation: Once the sod is laid, use a lawn roller to press it firmly into the soil. This improves root-soil contact and prevents air pockets.
8. Post-Installation Care
The initial weeks following sod installation are critical. Post-installation care ensures the sod takes root and establishes a healthy, vibrant lawn.
- Water Immediately: After installation, water thoroughly to saturate the soil beneath the sod (about 1 inch deep). Continue watering daily for the first 1–2 weeks.
- Avoid Foot Traffic: Limit traffic on newly laid sod to allow roots to establish. Consider fencing off the area on high-traffic commercial sites.
- Monitor for Pests and Disease: Keep an eye out for signs of fungal diseases or pests, particularly in humid or wet weather.
- Begin Mowing After Rooting: Once the sod is rooted (usually 2–3 weeks), mow at the recommended height for the grass type. Make sure mower blades are sharp.
Long-Term Payoff: Sod That Performs Under Pressure
With the right preparation, your commercial lawn will:
- Resist wear and tear from foot traffic and equipment
- Retain color and density throughout seasonal changes
- Support erosion control on exposed areas
- Elevate curb appeal, contributing to brand image and tenant satisfaction

FAQs:
How long does commercial sod take to establish?
With proper irrigation and care, sod typically establishes in 3–4 weeks. Heavy-use areas may take longer to fully root.
Can sod be installed on compacted commercial soil?
Not without remediation. We often loosen and amend compacted soil with organic matter and sand before sod is installed.
How do I maintain commercial sod after installation?
Ongoing watering, seasonal fertilizing, and annual overseeding help maintain commercial turf. We offer guidance as part of our lawn care services.
