Frequently Asked Questions
What grass seed should I use for my city in Canada?
It depends on your region and situation. On the BC coast, a perennial ryegrass + fine fescue blend; on the Prairies and the north, cold-hardy Kentucky bluegrass (Zone 3) + fine fescue; in Ontario and Quebec, a bluegrass + ryegrass blend; in Atlantic Canada, a bluegrass/fine fescue/ryegrass blend with creeping red fescue near salt water. For shade choose fine fescue; for drought choose tall fescue. Pick your city in the tool above for your exact blend, your seeding date, and where to buy it.
When should I seed or overseed a lawn in Canada?
Sow at least 6 weeks before your first fall frost so grass establishes before winter. That means early-to-mid August on the Prairies, late August to early September across southern Ontario, Quebec and the Maritimes, and into late September on the mild BC coast. Spring (a few weeks after your last frost) is the second-best window. The tool shows your exact date by city.
Is American grass seed okay for Canada?
Often no. Blends sold for US climates frequently contain warm-season grasses (bermuda, zoysia) that die in any Canadian winter, or ryegrass that winterkills on the Prairies. Always buy a cool-season blend rated for your Canadian zone — which is exactly what this tool recommends.
