Weed Control Calgary
Professional Weed Control for Calgary Lawns — Season-Long Results
Calgary lawns face a short, intense growing season and some of the most persistent broadleaf weeds in the country. Dandelions, clover, thistle, and creeping Charlie don't take breaks — and neither does our weed control program.
Cougarstone Lawn Care has been keeping Calgary lawns weed-free since 2011. Every one of our lawn care packages includes unlimited weed control — a full blanket treatment early in the season, followed by spot treatments on every fertilizer visit so weeds never get a second chance.

Our Program
How Cougarstone's Weed Control Program Works
Every Cougarstone lawn care package includes unlimited weed control — not one visit and done. Here's how the program runs through the Calgary growing season.
Early-Season Full Blanket Treatment
At the start of spring, we apply a comprehensive "full blanket" weed control treatment across your entire lawn. This application is timed to stop weeds before they have a chance to establish and spread — targeting common Calgary broadleaf weeds including dandelions, clover, and creeping Charlie. Products used are professional-grade, selective herbicides that target broadleaf weeds without harming your grass.
Spot Treatments on Every Fertilizer Visit
After the initial blanket treatment, any new weeds that emerge during the season are spot-treated on every scheduled fertilizer visit. We walk the lawn, identify active weed growth, and treat it directly. This keeps the pressure on weeds all season long without blanketing the entire lawn with product unnecessarily.
Unlimited weed control is included in every package. If weeds come back between visits, just call us — we'll schedule a free service visit to address it.
Fall Treatment & Season Close
Fall is actually one of the most effective times to apply weed control in Calgary. Weeds are drawing nutrients into their root systems before winter, which means herbicide applications are absorbed more efficiently. A fall treatment significantly reduces the population that re-emerges the following spring — which is why customers who stay on the program year over year see consistently better results.
Seasonal Timing
When to Apply Weed Control in Calgary
Calgary's growing season runs roughly May through October. Timing matters — applying weed control at the wrong time reduces effectiveness. Here's how we schedule treatments through the year.
May–early June. Pre-emptive blanket treatment stops dandelions and broadleaf weeds before they spread.
June–August. Ongoing spot treatments during fertilizer visits target any new weed growth.
September–October. Fall applications are absorbed into roots before dormancy — reduces next spring's weed population significantly.
November–April. No treatments needed. Fall prep determines how weed-free your lawn is when it comes out of dormancy.
Is October too late to spray for weeds in Calgary? No — October is actually one of the most effective times for broadleaf weed treatment in Calgary. Weeds are actively moving nutrients to their roots before freeze-up, which makes them highly receptive to herbicide. As long as daytime temperatures are above 10°C and no frost is imminent, a fall treatment is well worth doing.

Know Your Weeds
Common Lawn Weeds in Calgary — and How We Control Them
Calgary's climate — alkaline soil, cold winters, warm dry summers — creates ideal conditions for a specific set of persistent broadleaf weeds. Knowing what you're dealing with is the first step. Cougarstone's weed control program is designed around the weeds that actually show up on Calgary lawns.
Dandelions
Calgary's most widespread lawn weed. Deep taproots make hand-pulling ineffective — roots re-sprout unless fully removed. Professional selective herbicide treatment is the most reliable solution.
White Clover
Spreads aggressively by runners and seeds. Often mistaken for a harmless ground cover, but it competes directly with grass for nutrients and water. Selective broadleaf treatment controls it without harming turf.
Creeping Charlie
A low-growing perennial that spreads through shaded and moist areas. Difficult to control with a single treatment — requires follow-up spot treatments, which our unlimited program covers.
Canada Thistle
An aggressive spreader with an extensive root system. Common in SE and NW Calgary near open land. Spot treatment with a targeted broadleaf herbicide on repeat visits is the most effective approach.
Plantain
Broad-leafed weed that thrives in compacted soil — common in Calgary lawns with clay soil issues. Best controlled in combination with aeration to reduce the compaction that lets it establish.
Quack Grass
A grass-type weed that blends in until it sends up seed heads. Difficult to selectively control without harming turf — dense, healthy grass through fertilization is the best long-term defence.
A healthy lawn is the best weed defence. Weeds establish most easily in thin, stressed, or nutrient-deficient turf. Cougarstone's combined fertilizer and weed control program addresses both sides of the problem — the weeds that are there now, and the conditions that let them in.
