This question comes up more than you’d think.
Someone orders sod, the delivery shows up, and then something changes. The ground isn’t ready. The installer can’t make it that day. Life happens. And the sod is sitting there on the pallet in the driveway.
“Ryan, how long do I have before this goes bad?”
I’m Ryan Lingenfelter, owner of Cutting Edge Lawn & Landscaping in Garson, Ontario. Since 2020, I’ve installed sod on residential and commercial properties all across Greater Sudbury — Garson, Val Caron, Hanmer, Lively, Chelmsford, Azilda, Capreol. I’ve seen sod installed perfectly and I’ve seen sod that sat too long before going down. The difference in results is significant.
Here’s the honest answer — including what happens to sod at each stage of delay, and what to do if you’re in this situation right now.
The Short Answer — How Long Sod Actually Lasts
Fresh sod should be installed within 24 hours of delivery under normal conditions. That’s the standard I work to on every installation.
In Sudbury’s climate — especially in late May and June when most sod installations happen — that window gets even shorter. Here’s why.
Sod is a living product. It’s grass plants with a thin layer of soil and root material holding them together. Once it’s cut from the sod farm and rolled up, it stops receiving sunlight, water, and airflow. The rolls heat up from the inside out — especially when stacked on a pallet. In warm weather above 20°C, that internal heat builds fast and the grass starts dying from the inside before it ever touches your soil.
In cool, overcast conditions — a cloudy 12°C day in early May — you might get 48 hours before serious degradation starts. In full sun at 25°C in June, you’re looking at 12 to 18 hours before the quality starts dropping noticeably.
The honest rule: same day is ideal, next day is acceptable, 48+ hours is a problem.
What Actually Happens to Sod When It Sits Too Long
I want to walk you through this hour by hour — not to scare you, but because understanding what’s happening helps you make the right call when you’re standing in the driveway looking at a pallet of sod.
Hours 0 to 24 — Stressed but viable
Fresh off the farm and delivered, the sod is in good shape. The grass is green, the roots are moist, and it will establish well if installed today. If you need to hold it overnight, this is manageable — keep it in the shade, unstack the rolls if possible, and water the pallet lightly to keep the roots from drying out. Don’t soak it — just keep it moist.
Hours 24 to 48 — Declining
By day two, the internal temperature of the stacked rolls has been building. The grass at the centre of each roll has had no sunlight and limited airflow. You’ll start to see yellowing on the underside of some rolls. The roots are still alive but they’re under stress. Sod installed at this stage can still establish — but it needs more careful watering during the establishment period and it’s less forgiving of mistakes.
In Sudbury’s June heat, this decline happens faster. A pallet that sat through a warm day and a warm night is already showing stress by hour 36.
Hours 48 to 72 — Serious damage
At this point, you’re going to see obvious yellowing and browning in the rolled sections. The grass blades are dying. The roots may still be technically alive at the contact points, but the turf is weakened enough that establishment is significantly less reliable. Some rolls may be past the point where they’re worth installing.
If you install sod at this stage, you’re taking a real risk. Some of it will establish. Some of it won’t. You’ll likely end up with patchy results and potentially need to replace sections within a few weeks — which costs more than doing it right the first time.
72+ hours — Don’t install it
After 72 hours in warm conditions, most sod is dead or dying. The smell will tell you — decomposing grass has a distinct odour. The colour will tell you — it’ll be mostly yellow and brown rather than green. Installing dead sod is essentially laying down thatch. It won’t establish. You’ll be pulling it up and starting over anyway.
I’ve had homeowners call me after installing 3-day-old sod wondering why it isn’t greening up. The answer is always the same — the sod was already dead when it went down.
Sudbury-Specific Factors That Affect How Long Sod Lasts
A few things about Greater Sudbury specifically that affect this timeline.
Temperature swings
Sudbury has significant temperature variation — we can hit 28°C in June and drop to 8°C overnight. Sod sitting through a hot day degrades faster than the standard timeline suggests. If your delivery arrived on a warm afternoon, don’t assume the cool overnight temperature bought you extra time — the damage from the afternoon heat is already done.
Direct sun exposure
A pallet of sod sitting in full sun in a Sudbury driveway in June is in the worst possible conditions. The dark soil on the underside of the rolls absorbs heat rapidly. If you can’t install immediately, move the pallet to shade — the side of the house, under a tree, anywhere out of direct sun. This alone can extend your viable window by several hours.
Humidity
Sudbury is drier than southern Ontario. Lower humidity means the roots in the sod rolls dry out faster. This is another reason the 24-hour window matters more here than in wetter climates. Keep the pallet lightly misted if you’re holding it.
What to Do If Your Sod Has Been Sitting Too Long
If you’re reading this because the sod has already been sitting for a while and you’re not sure whether to install it or call the supplier — here’s how I’d assess it.
Check the colour
Unroll one section from the middle of the pallet — that’s where degradation happens fastest. If the grass is still mostly green with minor yellowing at the edges, it’s likely still viable. If it’s predominantly yellow or brown, it’s past the point of reliable establishment.
Check the roots
The root mat on the underside of the sod should be moist and cohesive. If it’s dry, crumbly, or pulling apart easily, the sod has dried out significantly. Dry roots are dead roots. No amount of watering after installation will bring them back.
Check the smell
Fresh sod smells like grass and soil. Deteriorating sod has a sour, fermented smell. If the smell is off, the sod is decomposing.
If the sod passes all three checks — mostly green, moist roots, normal smell — install it immediately and water heavily during establishment. If it fails any of them, call your supplier before installing. Installing bad sod is a waste of the labour and preparation work that went into the project.
How to Store Sod Properly If You Can’t Install It Immediately
Sometimes a delay is unavoidable. Here’s how to minimize the damage if you need to hold the sod for a day.
- Move it to shade immediately. This is the single most important thing. Direct sun is the enemy of stored sod.
- Unstack the rolls if possible. Stacked rolls trap heat in the centre. Laying them out flat in a shaded area allows airflow and slows the internal temperature buildup.
- Water lightly. Mist the root side of the rolls to keep them from drying out. Don’t soak — saturated sod sitting on a hard surface will rot faster than dry sod. Just keep it moist.
- Don’t fertilize it. Some people think adding fertilizer to stored sod will help it survive. It doesn’t. Fertilizer on stressed, uninstalled sod speeds up decomposition. Leave it alone.
- Install within 24 hours no matter what. Even with perfect storage conditions, the clock is running. Get it in the ground as fast as possible.
Why Timing the Delivery Matters More Than Most People Realize
This is something I always talk through with homeowners before we schedule a sod installation. The delivery date and the installation date need to be the same day — or as close as possible.
On jobs I manage, I coordinate the sod delivery to arrive the morning of the installation. The ground prep is done the day before. The crew is on site and ready when the pallet arrives. We’re installing within an hour or two of delivery, which is ideal.
Where I see problems is when homeowners order sod through a landscape supply company independently and assume they can install it themselves over a weekend — sod arrives Friday, they plan to lay it Saturday and Sunday. If Friday is hot, that sod is already compromised by Saturday morning. By Sunday, the back half of the pallet is a write-off.
If you’re doing a DIY sod installation in Sudbury, my strong advice: order the sod for the morning of the day you plan to install it. Not the day before. The day of. And have your ground prep completely finished before the delivery arrives so you can go straight from unloading to installing.
What Proper Sod Installation Looks Like in Sudbury
Since we’re talking about sod, I want to briefly cover what a proper installation involves — because the way the sod goes down is just as important as how fresh it is when it does.
The ground needs to be prepared before the sod arrives. Old material removed, soil loosened, graded properly so water drains away from the house. Any topsoil additions or amendments done and raked smooth.
The sod goes down in a staggered brick pattern — seams offset so you don’t get a continuous line that settles or separates. Each roll is butted tightly to the next with no gaps. Gaps dry out and die, leaving lines in the finished lawn.
Once it’s down, it gets rolled to press the roots into contact with the soil underneath. Air pockets between the sod and the soil are the other main cause of establishment failure besides waiting too long to install.
Then it gets watered — heavily, immediately. The first watering should saturate the sod and the top few inches of soil underneath. From there, daily watering for the first week, tapering as the roots establish.

When to Call Someone vs. Do It Yourself
DIY sod installation is absolutely possible if you’ve got the time, the right tools, and a manageable area to cover. The main things that go wrong on DIY installs are poor ground prep, gaps between rolls, and not watering enough during establishment — none of which are complicated to avoid if you know what to look for.
Where I’d recommend hiring it done:
- Large areas where the logistics of coordinating delivery, ground prep, and installation in a single day are difficult to manage alone
- Properties with slopes, drainage issues, or soil problems that need to be addressed before the sod goes down
- When you want the job done right the first time without the risk of having to replace sections that didn’t establish

Frequently Asked Questions
How long can sod sit on a pallet before it dies?
In Sudbury’s climate, fresh sod should be installed within 24 hours of delivery. In warm weather above 20°C — which is common in June — serious degradation can begin within 12 to 18 hours. After 48 hours, establishment becomes unreliable. After 72 hours in warm conditions, most sod is dead and should not be installed.
Can I store sod overnight in Sudbury?
Yes, with proper storage. Move the pallet immediately to a shaded area, unstack the rolls if possible to allow airflow, and mist the root side lightly to keep it moist. Even with ideal storage, install it first thing the following morning. Don’t push it to a second night.
What does bad sod look like?
Deteriorating sod will show yellowing and browning on the grass blades, dry or crumbly roots on the underside of the rolls, and a sour or fermented smell. Fresh viable sod is green, has moist cohesive roots, and smells like grass and soil. If in doubt, unroll a section from the middle of the pallet — that’s where degradation happens fastest.
What happens if I install old sod in Sudbury?
Sod that’s significantly degraded before installation will fail to establish properly. You’ll see yellowing that doesn’t green up, patchy dead sections within the first week or two, and roots that don’t knit into the soil underneath. In severe cases the sod effectively acts as thatch and will need to be removed and replaced.
How do I keep sod alive if installation is delayed?
Move it to shade immediately, unstack the rolls to allow airflow, mist the root side to keep it moist without soaking, and install as soon as possible — ideally within 24 hours. Do not fertilize stored sod. Do not leave it in direct sun. The goal is to slow the deterioration, not stop it — fresh sod cannot be stored indefinitely regardless of conditions.
