A lush, green lawn is every homeowner’s dream — but nothing ruins that picture-perfect yard faster than unwanted weeds. In Edmonton and throughout Alberta, weeds thrive in lawns that are stressed, thin, or not properly maintained. While it may seem like an endless battle, preventing weeds is much easier (and more effective) than constantly trying to get rid of them after they appear.
The best defense against weeds is a dense, healthy lawn. When grass is thick and strong, it naturally crowds out weeds by blocking the sunlight and limiting space for them to grow. Achieving this starts with proper mowing, watering, and fertilizing practices.
Thin or patchy areas are prime real estate for weeds. Overseeding these spots each spring or fall helps your lawn become denser and more resistant to weed invasion. Pair overseeding with aeration for the best results — this allows new seeds to establish strong roots and helps improve soil health.

A pre-emergent herbicide can stop weeds before they even sprout. These treatments work by creating a barrier in the soil that prevents weed seeds from germinating. Timing is crucial: in Edmonton, pre-emergent applications are typically done in early spring before soil temperatures rise.
Shallow, frequent watering weakens your lawn and encourages weed growth. Instead, water deeply and infrequently to help your grass develop a deep, robust root system that can outcompete weeds.

Regular lawn care tasks — like mowing, cleaning up debris, and aerating — help prevent weeds by reducing stress on your grass and improving soil health. A well-maintained lawn is less likely to suffer from weed infestations and is better equipped to resist pests and disease.
