Preparing soil properly before laying sod is essential for creating a beautiful, long-lasting lawn in Fredericton. What’s underneath the sod matters just as much as the turf itself. Think of soil preparation as setting the foundation for your lawn’s entire future.
Proper soil preparation helps new sod develop strong roots and thrive through seasons of heat, cold, and foot traffic. While these preparation steps require time and effort, they’re the difference between a lawn that lasts for years and one that disappoints quickly.
Soil preparation is a crucial step before laying sod that determines the long-term health and success of your lawn. Proper ground preparation starts with removing existing vegetation, weeds, and debris to eliminate competition for essential resources like water and nutrients.
The next vital step involves tilling the soil to a depth of 4-6 inches, which improves soil structure and creates an ideal environment for root growth. Adding organic matter during this process enhances soil fertility and helps retain moisture, promoting better grass establishment.
Correct grading during preparation ensures proper drainage, preventing water pooling and potential damage to nearby structures. It’s also essential to test and adjust soil pH levels, aiming for slightly acidic conditions around 6.5, which optimizes nutrient availability for the new grass.
When soil is properly prepared, it provides the perfect foundation for sod to develop strong roots quickly. This initial investment in preparation leads to a healthier lawn that requires less maintenance and thrives for long time.
The first step in soil preparation is thorough site clearing. Remove all debris that could prevent proper root development:
Use a rake to comb through smaller areas, removing even modest-sized rocks. For established weeds, apply herbicide about two weeks before soil preparation begins to prevent unwanted plants from competing with the new lawn for nutrients.
New sod requires direct contact with soil to establish roots properly. Any debris creates a barrier that can prevent sections of new sod from rooting effectively.
Proper grading directs water where it should go instead of where it shouldn’t. After clearing the site, shape the land by:
For small yards, a rake and shovel work well for rough grading. Larger areas may require commercial equipment like a box blade attachment for a tractor. Continue removing rocks and debris uncovered during this process.
The goal at this stage isn’t perfection—just establishing the basic shape and drainage patterns that will support the lawn for long time.
Tilling breaks up compacted soil, allowing air, water, and roots to penetrate deeply. Till to a depth of 4-6 inches across the entire installation area. For severely compacted areas, go deeper—6-8 inches.
To till effectively:
The difference after tilling is dramatic—soil that was once hard becomes loose and workable, ready for new lawn establishment.
For clay soils, till when the soil is slightly damp but not wet to prevent forming hard clumps. Small areas can be manually loosened with a garden fork, but most yards benefit from mechanical tilling.
Most yards benefit from adding fresh topsoil to create an ideal growing environment for new sod. Aim for a 4-6 inch layer of quality topsoil after settling. Look for:
Spread topsoil evenly across the yard, using a rake to maintain consistent depth. For extra fertility, mix in quality compost—about one part compost to three parts topsoil.
When calculating topsoil needs, order about 20% more than initial measurements suggest to account for natural compaction over time.
Testing soil pH is essential before installing sod. Turf grasses generally prefer soil with a pH between 6.0 and 7.5. Testing is simple:
Based on soil test results, make these adjustments:
Work amendments into the top 3-4 inches of soil thoroughly. If possible, allow a week or two for these materials to affect soil pH before laying sod.
Starter fertilizer provides specific nutrients that new grass needs during the critical establishment period. Unlike regular fertilizers, starter fertilizers contain higher phosphorus levels to stimulate root development. Look for formulations like 10-10-10 or 18-23-12.
To apply starter fertilizer properly:
Measure the yard accurately and follow recommended application rates to avoid over-application, which can harm new sod.
Finish grading creates the smooth, even surface necessary for perfect sod-to-soil contact. Using a landscape rake (the kind with a straight edge), methodically work across the yard to:
Pay special attention to areas along driveways and walkways. The final soil level should sit approximately ¾ inch below these features to account for the thickness of the sod.
The smoother the soil surface, the better the sod will establish and the nicer the lawn will look.
Fresh soil is often fluffy and will naturally compact over time. Pre-settling the soil prevents uneven lawn surfaces after sod installation:
This settling process eliminates air pockets that prevent good sod-to-soil contact and helps identify any final low spots before sod arrival.
If time permits, allow the area to receive rainfall or irrigation before laying sod to reveal any issues that need addressing.
The day before sod installation:
On sod installation day, the soil should be moist but firm enough to walk on without leaving deep footprints. If too wet, depressions will form; if too dry, the sod won’t have the moisture needed to begin rooting immediately.
If soil tests indicated low phosphorus levels, apply a phosphorus-rich fertilizer right before laying the sod to boost root development.

No, you should not lay sod directly on top of dirt without proper preparation. The soil needs to be cleared of debris, weeds, and old grass, and tilled to enhance structure and drainage. Testing and amending the soil for pH and nutrients are also essential for healthy root establishment, ensuring the sod can thrive.
It depends on various factors such as the size of the area, the type of sod chosen, and any additional preparation needed for the soil. For an accurate estimate, it’s best to consult with our professionals who can assess your specific project.
The best time to install sod in Fredericton is during early spring or early fall. These seasons provide ideal temperatures and moisture levels for successful establishment. Installing sod at these times helps ensure a healthy and vibrant lawn.
