The Best Time To Overseed Your Lawn In Alberta
Want a lush, even lawn? Overseeding thickens thin patches and revives grass scorched by Alberta’s summer heat. The best time to overseed your lawn in Alberta is late August to mid-September, when warm soil and cool nights speed germination and suppress weeds.
Our team at Greener Grass can handle the overseeding, from the right seed mix to precise fertilization, so your yard emerges thick, lush, and ready for next spring. This post explains why overseeding works, breaks down each step, and offers pro tips to keep that fresh green carpet looking its best all season long!
What is Overseeding?
Overseeding involves applying seed directly to the existing turf without tearing up the soil or grass. This method is an easy way to fill bare spots, improve the resilience and density of the lawn, and enhance its colour. If you notice that your lawn has become prone to disease or requires increased water and fertilizer, overseeding is a perfect solution.
Some benefits of overseeding include:
- Fewer weeds – A worn-out lawn invites weeds to grow and spread – overseeding results in a thicker lawn, which naturally controls weeds.
- A resilient lawn – A healthy and lush lawn can withstand common stressors such as heat, dry weather, snow, foot traffic, compacted soil, and weather extremes.
- Improved appearance – No more patchy areas! Applying seed directly to the turf fills in bare spots and enhances the overall aesthetic of your lawn.
When to Overseed Your Lawn
While overseeding works almost year-round, timing is everything for success in Canada’s cooler climate. For the best time to overseed your lawn in Alberta, aim for:
- During the growing season in spring, before the summer heat sets in.
- Late summer or early fall (late September to the middle of October).
- When the soil temperature is between 10-20 degrees Celsius.
Overseeding during cooler days helps germinate the grass seed without the risk of the summer heat disrupting growth. Having a strong and healthy lawn during the winter when the weight of snow settles in ensures thick and resilient grass come springtime.

Overseeding FAQ
How should I get the lawn ready before Greener Grass arrives?
Mow shorter than usual, bag the clippings, and rake out any remaining thatch. If you can, give the lawn a quick pass with a core aerator—this opens the soil so our premium seed makes perfect contact and germinates fast.
How do I care for the lawn after overseeding?
Keep the top inch of soil moist with light, frequent waterings. Once the new grass reaches 3 inches, return to regular mowing and a deeper, less-frequent watering routine.
When can kids and pets start using the lawn again?
Limit foot traffic for three to four weeks. After the first mow, the new turf is established enough for regular play.
