Are you watering your lawn enough—or far too much—this summer in Canada?
Most homeowners aren’t sure. And that uncertainty could quietly be ruining your lawn, wasting water, or driving up your utility costs.
Here’s what many people don’t realize: in Canadian summer weather, your lawn typically needs just 1 inch (2.5 cm) of water per week, including rainfall.
That translates to about an hour of watering, but only when done right, early in the morning when it’s cool, and before evaporation sets in.
Watering too often or too late in the day can invite fungal diseases, weak root systems, and dry or patchy grass. And if your sprinkler system isn’t properly set, you could be overwatering—or under-watering without knowing.
For seniors and families, especially, lawn upkeep can feel overwhelming.
That’s why we (at Custodia) offer free consultations, fast lawn system checks, and expert support across Canada.
Don’t wait for brown grass or city fines. Act now to protect your yard, your budget, and your peace of mind—all summer long.
How Much Water Does My Lawn Need?
In Ontario’s hot summers, what truly matters isn’t just how long you water—it’s how deeply that water reaches.
Many homeowners unknowingly waste water by lightly sprinkling the surface, leaving roots thirsty and lawns vulnerable.
A healthy lawn thrives from soak-and-set watering, letting water reach deeper into the soil. This supports strong root systems, which means greener, thicker grass that stands up better to heat, foot traffic, and even drought.
Here’s the real difference:
Deep Watering
Deep watering allows moisture to soak 6–8 inches into the soil, pushing roots to grow downward. This makes your lawn more resilient, even in drought or high heat.
It reduces the need for frequent watering and helps maintain a thick, green lawn, perfect for family time and summer gatherings.
Shallow Watering
Shallow watering barely moistens the surface, leaving roots weak and close to the topsoil.
This exposes the grass to heat stress, browning, and disease. Lawns watered this way dry out quickly and require constant maintenance, costing you more time, money, and energy throughout the summer.
If you’re unsure how deep your watering goes, Custodia’s lawn specialists near me in Ontario can check it for you.
What Is The Best Time To Water Grass In The Morning?
Knowing when to water your lawn can save you time, money, and a lot of frustration. In Ontario’s summer heat, the best window is early morning—from 4 to 10 a.m.
This simple habit helps reduce water loss through evaporation and, more importantly, prevents lawn diseases that thrive in damp evenings.
Watering early means your grass soaks up the moisture it needs before the sun bakes it dry. Plus, watering at this time keeps fungal growth at bay, which can turn your lush lawn into a patchy mess overnight.
Worst Time To Water Grass?
Avoid watering in the mid-afternoon when the heat causes most water to evaporate before it even reaches the roots. Evening watering might seem convenient but risks fungal infections that take weeks to fix.
How Long To Water Grass With a Sprinkler?
Watering frequency and duration depend on your soil type and sprinkler output.
In Ontario, clay soils retain moisture longer and usually need watering once a week, while sandy soils drain quickly and require watering twice a week.
For example, if your sprinkler delivers about 1 inch of water per hour, aim for 60 minutes total per week, which can be split into two 30-minute sessions. This ensures deep, even watering without wasting precious water.
Here’s a simple trick: place empty tuna cans around your lawn to measure how much water your sprinkler delivers.
Adjust your watering time until each can collects about 1 inch of water. This hands-on approach prevents overwatering and helps keep your water bills low.

Smart Watering Tips Every Canadian Homeowner Should Know
Watering a lawn shouldn’t feel like a guessing game. With rising utility costs, environmental concerns, and seasonal changes, homeowners in Ontario need to get smarter—not just wetter—when it comes to watering routines.
Install Smart Irrigation Controllers
These systems adjust watering times based on real-time weather, reducing waste and overwatering.
Mulch Grass Clippings
Don’t bag your lawn clippings. Let them decompose naturally. This keeps the soil cooler and helps retain moisture longer between waterings.
Use Rain Barrels or Greywater Systems
Capture rainwater from gutters or repurpose household water (from rinsing veggies, for example). It’s eco-friendly and free.
Skip Watering During Rainfall or Bans
Overwatering can drown your grass and lead to fungal disease. During heavy rain or city-issued bans, let nature take over.
These smart habits protect your lawn, your wallet, and your weekends.
And let’s face it—no one wants to spend Saturday fixing sprinkler mistakes. You’d rather spend it enjoying your space. Thankfully, Custodia can assess, install, or fine-tune your system—get expert advice today.
