After months of heat, drought, foot traffic and summer stress, it’s common for lawns to look thin, patchy, or worn out. But don’t wait until spring to fix it. Fall can offer some of the best conditions of the year for establishing new turf.
Whether you're starting a brand-new lawn or simply overseeding thin and damaged areas, taking advantage of the fall growing window can help you head into winter with a healthier, more established stand of grass.
Why Fall Is the Perfect Time to Seed
-
More moisture, less stress
Cooler temperatures and increased rainfall generally mean less moisture is lost through evaporation. This helps keep the seedbed consistently moist during germination and reduces the need for constant irrigation compared with the heat of summer. -
Less competition from weeds
As temperatures cool, many summer annual weeds begin to slow down or go dormant. With less competition for resources, newly germinated turfgrass has a better opportunity to establish. -
Less heat, more recovery
Established turf can recover from summer stress while newly seeded grass takes advantage of the milder conditions.
Don’t Let the Clock Run Out! Timing Is Everything
As a general rule, aim to seed approximately 6–8 weeks before your area's expected first frost. This gives the grass enough time to germinate, establish, and develop a healthy root system before winter arrives.
If you seed too late, declining soil temperatures can significantly slow germination and establishment. Once temperatures drop too far, your new seedlings may not have enough time to establish before winter dormancy.
In BC, your ideal seeding window will vary depending on your location, elevation and local weather conditions. Coastal areas and the Interior can have very different fall timelines, so local conditions matter.
Don't Just Throw Down Seed
Successful fall seeding isn't only about when you seed — it's also about what you seed and how you prepare the site.
Before seeding:
- Choose the right seed: Different turfgrass species offer different strengths, including drought tolerance, shade tolerance, traffic tolerance and winter performance. You can learn more about our turf grass species here.
- Mow: Mow the existing lawn at an appropriate height and remove excessive thatch or debris.
- Prepare the soil: Once the seeding area has been raked or top soil has been added, create a firm seed bed to spread your seed onto.
While seeding:
- Seed at the correct rate: Too little seed can leave gaps; too much can create excessive competition between seedlings.
- Help the seed establish: After seeding at the recommended rate, rake and lightly cover to a maximum depth of ¼ inch. Finally, roll to press the seed into firm contact with the soil.
- Water: Make sure you water enough to wet the entire area, but take care not to wash away the seed. Use a gentle stream rather than a harsh spray.
After seeding:
- Keep the seedbed consistently moist: Avoid letting newly seeded areas dry out during germination.
- Fertilize appropriately: Providing the right nutrients can support establishment and root development, but fertilizer selection and timing should be based on your soil and turf needs. For example, RG 16-32-6 Turf Starter is a great sod starting fertilizer.
