New sod looks great the day it's laid down, but how well it survives the following weeks depends almost entirely on what's underneath it. Skipping ground prep is the single biggest reason new sod fails to root properly, develops dead patches, or looks uneven within the first season. Here's what actually needs to happen before sod goes down.
Remove the Old Lawn Completely
Existing grass and weeds need to be fully removed, not just cut short or covered. Old grass left in place decomposes unevenly under new sod, creating air pockets and inconsistent settling that shows up as bumps and low spots later.
Grade the Soil
Proper grading does two things: it directs water away from your foundation instead of pooling near it, and it creates an even surface so the new lawn doesn't end up with visible dips and high spots. This step gets skipped more than any other, and it's the one homeowners most regret skipping once the sod has rooted in and the unevenness is permanent.
Amend the Soil
New sod roots into whatever soil is underneath it. If that soil is heavily compacted, very sandy, or low in organic matter, working in quality topsoil or compost before installation gives roots something to actually grow into, rather than fighting poor soil from day one.
Time It With the Weather
Sod establishes best in cooler, wetter conditions — spring and early fall are the strongest windows in the GTA West. Installing in peak summer heat means significantly more watering and a higher risk of stress before the roots are established.
Water Immediately and Consistently
New sod needs to be watered within thirty minutes of being laid, and kept consistently moist (not soaked) for the first couple of weeks while roots establish. Letting it dry out during this window is one of the most common causes of patchy, failed sod.
Hold Off on Heavy Use
It's tempting to use a freshly sodded yard right away, but foot traffic before the roots have taken hold can shift sections out of place or stop them from rooting evenly. Most new sod needs two to three weeks of light or no traffic before it can handle regular use.
Getting the Prep Right the First Time
Because so much of sod's success depends on what happens before it's even delivered, proper grading and soil prep is worth getting right rather than rushing.
