Spring 2026 — What's Coming & When to Seed

Thanks for checking in on us. Here's what you need to know heading into the season.

When We're Opening

We're restocking our full 2026 lineup and expect to be open for orders in late March, which still gives you enough time to line up your project with optimal Canadian seeding windows (more on that below). If you want to be notified the moment we're live, drop your email below — we'll send you one email when the store opens, nothing before.


What's New for 2026

We've been working on some things we're genuinely excited about this year.

We're introducing a new seed option that a lot of you have been asking us about over the last couple of years, as well as something to help take the guesswork and complexity out of regular lawn feeding. And SeedLaunch Pro, our professional starter fertilizer, has been reformulated for 2026 with an updated format and improved slow-release performance.

More details on everything when we open. For now, the most useful thing we can share is when you should actually be putting seed down this spring.

When to Actually Seed This Spring

One of the most common spring seeding mistakes is starting too early. Warm air on a sunny March afternoon can feel like it's time — but grass seed germinates based on soil temperature, not air temperature. Soil warms up much more slowly than the air, and planting into cold soil means seed sitting dormant, exposed to birds, washout, and rot.

Cool-season grass seed needs consistent soil temperatures of 10°C (50°F) or higher to germinate reliably. That typically requires daytime air temps holding steady in the 15–20°C range for a sustained period — not just one or two warm days.

Here's a realistic look at when seeding conditions arrive across Canada:

Vancouver & Lower Mainland April onward. March soil is typically still too cool and saturated — even on the coast.
Southern Ontario & Quebec Late April through May. Often mid-May. Soil takes time to warm after snowmelt.
Prairies Mid-May to early June. Later start, but long days make up for it.
Atlantic Canada May. Spring arrives later, but conditions are excellent once they settle.

The good news: even if you're seeding in mid-to-late May, you have plenty of time for strong establishment before summer heat. There is no rush. Seed planted into properly warm soil with consistent watering will outperform seed planted three weeks earlier into cold ground — every time.

For what it's worth, I live in the Greater Toronto Area, and in each of the last three years I've waited until the last two weeks of May to seed my own lawn. That's when I felt temps were where I wanted them. Use the time between now and your seeding window to prep. Rake out debris, address any grading issues, and plan your watering setup. When the soil is ready and our store is open, you'll be set to go.
