Why Aeration and Overseeding Are Essential for Calgary Lawns
Calgary’s clay-heavy soils and freeze-thaw cycles create compacted ground that restricts water, oxygen, and nutrients from reaching grass roots. Aeration relieves this compaction by creating small holes in the soil. Overseeding introduces new grass seeds to thicken the turf and fill bare spots. Together, these services rejuvenate your lawn, so it’s more resilient to Alberta’s harsh weather, foot traffic, and weed invasions.
Our team at Yard Dawgs uses professional-grade techniques like mechanical aeration and slit-seeding to ensure lasting results. Our weed-free guarantee and personalized care make us a trusted choice for lawn care in Calgary and beyond.
When Is the Best Time to Aerate and Overseed in Calgary?
Timing your aeration and overseeding correctly ensures the best results for your lawn. In Calgary and surrounding areas like Edmonton, Red Deer, and Saskatoon, the ideal windows are:
- Spring (Late April to Early June). After the ground thaws, spring aeration stimulates root growth and prepares your lawn for fertilization and seeding. Overseeding in spring helps establish new grass before summer heat arrives.
- Fall (Late August to Mid-September). Cooler nights and warm soil create perfect conditions for germination. Fall aeration repairs summer damage, and overseeding strengthens the lawn for winter dormancy.
Avoid aerating or overseeding during peak summer heat or late fall, as extreme temperatures or early frost can hinder grass establishment.
Why These Seasons Work
- Soil Temperature – Grass seeds germinate best when soil temperatures are between 10-20°C, common in spring and early fall.
- Moisture Availability – Calgary’s spring rains and fall’s moderate weather provide the moisture needed for seed growth without drought stress.
- Weed Suppression – Overseeding in early fall helps new grass outcompete weeds, aligning with our weed-free guarantee and weed control services.

How to Prepare Your Lawn for Aeration and Overseeding
To maximize the benefits of aeration and overseeding, follow these preparation tips:
- Mow Low. Trim your grass to 1.5–2 inches to allow better seed contact with the soil.
- Clear Debris. Remove leaves, sticks, or thatch to ensure a clean surface for aeration.
- Water Lightly. Moisten the soil a day or two before our team arrives, but avoid overwatering to prevent muddiness.
- Mark Utilities. If you have sprinklers or underground cables, flag them to avoid damage during mechanical aeration.
Post-Treatment Care for a Thriving Lawn
After aeration and overseeding, proper care ensures your lawn establishes quickly and stays healthy:
- Water Consistently. Keep the soil moist with light, daily watering for 2–3 weeks to support germination. Avoid heavy watering that could wash away seeds.
- Delay Mowing. Wait until new grass reaches 3 inches (about 3–4 weeks) before mowing to allow roots to establish.
- Limit Traffic. Keep kids and pets off the lawn for at least three weeks to protect young grass.
- Fertilize Strategically. Our fertilizer and super juice applications post-aeration provide essential nutrients without overwhelming new growth.
Our dedicated success team is always available to answer questions or adjust your care plan, ensuring your lawn remains lush and healthy.

Common Questions About Aeration and Overseeding
How soon can I walk on my lawn after overseeding?
Limit foot traffic for 3–4 weeks to protect new grass. After the first mow, your lawn is ready for normal use.
Can I fertilize right after overseeding?
Yes, fertilizing post-aeration boosts growth. Our super juice and sea kelp treatments are applied at the right time to support new grass without burning it.
What if weeds appear after treatment?
With our weed-free guarantee, we’ll re-spray any weeds that appear between treatments at no extra cost.
How does slit-seeding differ from regular overseeding?
Slit-seeding uses specialized equipment to place seeds directly into the soil, ensuring better germination than broadcasting seeds. It’s ideal for thinning lawns or bare patches.
