I want to talk about something I see constantly working across Greater Sudbury — on residential properties in Hanmer, Val Caron, Chelmsford, Lively, Garson, and everywhere in between.
It’s not a complicated problem. It’s not an expensive one to fix. But it quietly damages more lawns in this area than almost anything else I can think of, and most homeowners don’t even realize they’re doing it.
I’m Ryan Lingenfelter, owner of Cutting Edge Lawn & Landscaping in Garson. I’ve been cutting grass professionally across Greater Sudbury since 2020. And in that time, if I’ve seen this mistake once, I’ve seen it a thousand times.
Here’s what it is, why it matters specifically in Sudbury, and exactly what to do differently.
The Mistake — Cutting Too Short
The single most common mistake I see Sudbury homeowners make with their lawns is cutting the grass too short.
I know that sounds almost too simple. But I want you to understand how widespread this is and how much damage it causes before you write it off as obvious.
The most common reason people cut short is the same reason I understand completely: they want to go longer between cuts. If you mow the lawn down to an inch and a half, it takes longer to grow back to the point where it looks shaggy. You mow less often. That feels efficient.
The second reason I hear is appearance. Some people think short grass looks neater. More manicured. Like a golf course. And in certain contexts — actual golf courses, specifically maintained sports turf — short grass is appropriate because those surfaces use specific grass varieties and maintenance regimes designed for it.
The grass in your Sudbury residential lawn is not golf course turf. It’s cool-season turf — Kentucky bluegrass, fine fescue, perennial ryegrass blends — and it has completely different requirements. Cutting it short doesn’t make it look like a golf course. It stresses it, weakens it, and over time it kills it.
Here’s why.
What Scalping Actually Does to Your Lawn
When you cut grass very short — what’s called scalping — you’re removing most of the leaf blade. That leaf blade is not just the part you see. It’s the engine of the plant.
Grass leaves are where photosynthesis happens. The longer the leaf blade, the more surface area the plant has to capture sunlight and convert it into energy. Cut that blade down to an inch and a half and you’ve drastically reduced the plant’s ability to feed itself.
Here’s the cascade of problems that follows:
The Plant Goes Into Stress Mode
When grass is cut severely short, it redirects all available energy from root development into trying to regrow leaf surface as quickly as possible. That sounds okay — regrowth is good, right? — but it comes at a cost. Root development stops. The plant is burning energy reserves just to survive, not to strengthen its root system.
In Sudbury specifically, this matters enormously. Our summers get genuinely hot in July and August. A lawn with deep, established roots can access soil moisture from several inches down and handle heat stress. A lawn that’s been repeatedly scalped has shallow roots sitting in the top inch or two of soil — which dries out first and fastest. That lawn is going to go brown and struggle the moment we hit a dry stretch in summer, regardless of how much you water the surface.
The Soil Gets Exposed
Short grass means more sunlight hits the soil surface directly. Warm soil dries out faster. It also creates ideal conditions for weed germination — many common lawn weeds, including crabgrass and creeping charlie, thrive in bare or thin turf with exposed soil. Scalped lawns almost always have more weed pressure than lawns maintained at the right height. The short grass isn’t keeping the weeds out — it’s inviting them in.
Disease Pressure Increases
Short, stressed grass is more susceptible to fungal disease. This is particularly relevant in Sudbury where we can get stretches of humid weather in summer. Dollar spot, brown patch, and other common turf diseases establish more easily in weakened, scalped lawns than in healthy ones maintained at the right height.
The Damage Compounds Over Time
One scalping doesn’t ruin a lawn. But repeated short cutting over a season — or several seasons — does cumulative damage that gets harder and harder to reverse. I’ve walked lawns that have been cut short for five or six years and the soil compaction, the shallow root system, the thin coverage — it all adds up. What started as a maintenance habit ends up requiring a full restoration to fix properly.
The Right Mowing Height for Sudbury Lawns
Here’s the number I want you to remember: 3 inches.
For cool-season turf in Greater Sudbury — which is what almost every residential lawn in this area is — 3 inches is the target mowing height through most of the growing season. Some people go as low as 2.5 inches and that’s acceptable. Going lower than that regularly is where the problems start.
In summer — July and August specifically — I actually recommend going slightly higher. 3 to 3.5 inches. Here’s why: taller grass shades the soil surface, which keeps it cooler and retains moisture longer. During the hottest, driest part of a Sudbury summer, that extra half inch of height makes a real difference in how the lawn handles heat stress.
The rule I apply on every lawn I maintain is the one-third rule: never remove more than one-third of the total blade length in a single mow. So if your grass is at 4.5 inches, the lowest you should cut it is 3 inches. If it’s at 3 inches, don’t cut below 2 inches.
This rule matters most in spring when the lawn is coming out of dormancy and in fall when it’s preparing for winter. Cutting too aggressively in those transition periods sets the lawn back significantly.
I’ll also say this: if you’ve been cutting your lawn short for a while and you want to transition to the right height, don’t try to do it in one cut. Raise the deck height gradually over two or three mows. Going from 1.5 inches to 3 inches in one cut actually shocks the lawn because the lower parts of the blade haven’t been exposed to sunlight and the sudden change stresses the plant. Gradual is better.
The Other Thing That Makes It Worse — Dull Blades
Cutting height is the main issue I see. But there’s a second factor that compounds it on almost every residential property I visit: dull mower blades.
A sharp blade cuts grass cleanly. A clean cut heals quickly — the grass blade seals over the cut surface fast, limiting moisture loss and disease entry points.
A dull blade doesn’t cut. It tears. If you look at the tips of your grass blades after mowing and they look ragged, frayed, or brown at the tips within a day or two — that’s a dull blade. The grass isn’t being cut, it’s being ripped, and that torn tissue is an open wound on every single blade across your entire lawn.
Torn grass tips turn brown quickly. They’re more susceptible to fungal disease. They lose moisture faster. And a lawn that’s been mowed with a dull blade consistently looks worse than one that’s been cut cleanly — it has a brownish, hazy appearance even right after mowing.
How often should you sharpen your blade? For a standard residential lawn mowed weekly through a Sudbury season, sharpening once or twice per season is a minimum. If you’re mowing over any gravel, exposed tree roots, or other hard surfaces, sharpen more frequently. It takes thirty minutes and a file, or a few dollars at a sharpening service. It’s one of the highest-return maintenance tasks there is.
At Cutting Edge, we sharpen our blades regularly throughout the season. It’s a basic standard of professional lawn care that makes a visible difference in the result.
How to Know If You’ve Been Cutting Too Short
If you’re not sure whether your current mowing height is causing problems, here are the signs I look for on properties across Greater Sudbury:
- Lawn goes brown quickly after mowing, especially in summer
- Thin, sparse coverage with lots of soil visible between grass plants
- Weed pressure that seems to get worse every year despite treatment
- Lawn struggles badly in July and August even with watering
- Brown or ragged tips on grass blades within a few days of mowing
- Bare patches that keep reappearing in the same spots
- Lawn comes out of winter looking thin and patchy even after good fall prep
Any of these on their own could have other causes. But if you’re seeing several of them and you’ve been cutting your lawn short — that’s almost certainly a major contributing factor.
The fix is simple: raise the deck, sharpen the blade, and be consistent about it. Give the lawn two to three months at the right height and you’ll see a difference. It won’t be overnight, but it will be real.
Want Someone Else to Handle It?
If you’d rather have a professional maintain your lawn at the right height with sharp equipment throughout the season — that’s exactly what we do. Every cut at the right height, every time. No scalping, no dull blades, clean edges, consistent schedule.
Grass cutting starts at $39 for a standard residential property. If you want to know what it would cost for your specific lawn, call or text and I’ll give you a straight number.
