Grass plants naturally thin out over time and without routine overseeding, even healthy lawns can begin to decline within just a few seasons. In fact, many of the bare patches you see after winter aren’t just from snow or ice damage, they’re signs your turf is aging and losing its ability to regenerate.
That’s why overseeding your lawn in spring is a game-changer, especially in regions like Calgary, Edmonton, Red Deer, and Saskatoon, where tough winters and compacted soil take a serious toll on grass health. Spring offers the ideal combination of cool temperatures and moist soil. It gives new seeds the best chance to germinate and establish strong roots before summer heat sets in.

What Is Overseeding and Why Is It Important?
Overseeding is the process of adding new grass seed over existing turf to fill in bare spots, improve thickness, and enhance colour and disease resistance. In spring, soil temperatures warm up, moisture levels are ideal, and grass is in active growth making it the perfect time to seed.
Why overseed your lawn in spring?
- Revives thinning or patchy grass after winter damage
- Improves resistance to weeds, pests, and disease
- Enhances curb appeal with denser, greener turf
- Strengthens lawn health before summer heat
Unlike full lawn replacement, overseeding is less invasive and far more cost-effective, but only when done right.
Step-by-Step: How We Overseed Lawns in Spring
At Yard Dawgs, overseeding is a part of a proven program designed to get real results. Here’s what goes into a successful overseeding treatment.
1. Lawn Inspection & Soil Preparation
Before any seed goes down, we assess your lawn’s condition and tailor your treatment plan.
To prepare the surface for seeding, we offer:
- Mechanical Aeration: Loosens compacted soil and opens pathways for air, water, and nutrients.
- Liquid Aeration: For clients who prefer a no-plug solution that penetrates deeper and supports microbial activity.
- Thatch removal & cleanup: Excess thatch can choke out new seed, so we remove buildup and surface debris before seeding.
Want next-level seed-to-soil contact? Our slit-seeding & lawn seeding services use precision equipment to slice shallow grooves into the soil and deposit seed directly into them, drastically improving germination rates compared to broadcast spreading.
2. Seed Selection & Application
We choose a grass seed blend suited to your yard’s sun/shade conditions, soil type, and regional climate. Whether it’s Calgary’s dry summers or Saskatoon’s cooler temps, our seed matches your needs.
To ensure even coverage:
- We calibrate application rates based on lawn size and condition
- We avoid over-seeding shady or poorly-drained areas that may suffocate new growth
- We coordinate seed timing with other treatments (like fertilizer) to maximize success
How to Care for Your Lawn After Overseeding
New grass seed is delicate and proper care during the first few weeks is critical. Our continuous lawn care plans include everything your new turf needs to thrive.
Post-Overseeding Must-Dos:
- Water Frequently (but Lightly)
Keep the soil consistently moist, especially during the first 2-3 weeks. Light watering once or twice daily helps seeds germinate without drowning them.
- Hold Off on Mowing
Avoid cutting your lawn until new grass reaches 3 inches in height. This allows roots to anchor before they’re disturbed.
- Skip the Foot Traffic
Too much activity can compact soil and crush delicate seedlings. Keep kids, pets, and equipment off the lawn for at least 2-3 weeks.
Supporting Growth: Ongoing Treatments That Make the Difference
Overseeding is just the beginning. At Yard Dawgs, we support new growth with a suite of specialized treatments designed to strengthen turf, prevent weeds, and keep your lawn green and healthy all season long.
