About Green Guard Lawn
Green Guard Lawn Fertilization & Weed Control is proudly owned by Brian Swain, a lawn care expert with more than 10 years of hands-on experience here in Calgary. Brian started Green Guard because he noticed something was missing: many lawn companies were rushing through jobs without really caring about the details or the clients.
Green Guard does things differently. We value clear communication, respect for your time, and delivering results that make a real difference. Our goal isn’t to become Calgary’s biggest lawn company—we strive to become your trusted partner in maintaining a lush, healthy lawn.
Every Visit Is Photo-Verified!

You get a visual timeline that shows your lawn’s improvement from month to month, so you can feel confident about your investment. Because we take the extra time for this step, you can always trust your lawn is receiving the careful, thorough service it deserves.

Our Lawn Services
Keeping Calgary Lawns Green, Healthy, and Weed-Free
Green Guard’s lawn services are built specifically for Calgary’s tough growing conditions. From invasive weeds and compacted soil to unpredictable weather, each of our specialized treatments directly addresses real challenges local homeowners face. No fluff—just reliable solutions and noticeable results.
Weed Control
Weeds don’t just look bad—they steal water, nutrients, and space from your grass. Green Guard’s treatments quickly eliminate stubborn weeds like dandelions and chickweed, giving your lawn room to grow thicker and healthier. Our seasonal packages include unlimited weed control. Additionally, Calgary’s city bylaws require homeowners to manage invasive weeds. Green Guard proactively helps you stay compliant, giving you peace of mind and a beautiful, weed-free lawn all season.
Overseeding
Overseeding applies fresh grass seed directly onto your lawn, filling patchy areas and boosting grass density. Green Guard strategically includes overseeding in our lawn care packages because it naturally helps grass resist weeds, disease, and Calgary’s harsh weather. By applying high-quality seed at optimal times, your lawn becomes thicker, greener, and more resilient. Overseeding is one of the most effective ways to rejuvenate your grass, giving you a visibly healthier lawn year-round.
Mosquito and Tick Control
Mosquitoes don’t just ruin your outdoor fun—they also pose potential health risks. Green Guard applies an effective, all-organic repellent to mosquito and tick-prone areas on your property. Regular applications significantly reduce pest populations, so you can comfortably enjoy your yard without worrying about bites or insect borne diseases (Zika, Lyme disease, and West Nile virus). Our natural mosquito control treatments are safe for kids, pets, and your landscape, giving you a worry-free outdoor experience.
Fertilization
Fertilization is essential for maintaining a healthy, vibrant lawn in Calgary’s challenging climate. Green Guard applies specialized fertilizers tailored to your lawn’s specific seasonal needs, promoting deeper roots, thicker growth, and improved drought resistance. Unlike generic treatments, our combination of slow-release and fast-acting fertilizers provides steady nourishment throughout the entire season, making your grass healthier, greener, and stronger.
Liquid Aeration
Traditional mechanical aeration risks damaging sprinkler systems and can unintentionally transfer pests like chinch bugs between properties. That’s why Green Guard uses liquid aeration, an innovative and safer approach that loosens compacted soil without heavy equipment. Liquid aeration increases oxygen, water, and nutrient penetration deep into the root zone, creating stronger, more resilient grass. There’s no need to mark sprinkler heads, and it allows us to thoroughly treat even small or hard-to-reach yards, providing superior results without risks or hassle.
Super Biostimulant
Calgary lawns often struggle with extreme weather conditions, from droughts to rapid temperature shifts. Green Guard’s Super Biostimulant treatment helps grass efficiently absorb water and essential nutrients even under stressful conditions. Think of it as a revitalizing boost—it opens the pores of your grass blades, allowing them to take in nourishment more effectively. Packed with micronutrients, this unique treatment promotes sustained healthy growth, resulting in visibly greener, stronger, and more vibrant grass all season.

Green Guard Lawn Fertilization & Weed Control FAQ
How quickly will weeds disappear after treatment?
After your weed control treatment, weeds typically start wilting within a few days within 7–14 days. You’ll notice gradual results rather than instant removal because the weeds need time to naturally break down.
Is weed control safe for kids and pets?
Yes, our weed control treatments are safe once dry, usually about two hours after application. As an extra precaution, we always send you photo verification with a timestamp, so you’ll know exactly when the treatment happened and when it’s safe to enjoy your lawn again.
How often do you treat my lawn during the season?
Treatment frequency depends on your chosen package. Typically, we treat your lawn every 4–6 weeks throughout Calgary’s growing season to keep your grass consistently healthy, weed-free, and looking its best.
Why does my lawn need fertilizer treatments?
Calgary’s rapidly changing weather—from dry, sunny periods to sudden cold snaps—puts extra stress on lawns. Fertilizer treatments provide vital nutrients to strengthen your lawn’s root system, keeping your grass thick, healthy, and green even through Calgary’s temperature swings.
Why do you use liquid aeration instead of traditional aeration?
We switched to liquid aeration because it eliminates pest transfer, protects sprinkler heads, and allows us access to tight spaces and smaller yards. As always, each liquid aeration treatment is verified with photo proof, ensuring you see exactly what we’ve done for your lawn. We are fans of Liquid Aeration but was also offer Deep Core Mechanical Aeration if that is your preference.
When is the best time to overseed my lawn?
The ideal time for overseeding in Calgary is spring or early fall. Overseeding helps fill in bare patches and thickens your lawn, making it stronger and more resilient against weeds and diseases.
How do your mosquito control treatments work?
We use an all-organic mosquito repellent that’s safe and effective.Insert Regular applications throughout the season target mosquito breeding areas, allowing you to comfortably enjoy your yard without those pesky interruptions.
Do I need to be home during treatments?
Nope, you don’t need to be home during your treatment. To keep you informed, we’ll email you a verified photo each time we visit, showing exactly what we’ve done. This transparency means you’ll always know your lawn has been treated properly, even if you’re away or at work.
Can I get a custom lawn care or weed control package?
We’re always ready to design a package that matches your exact lawn care needs. Owner Brian Swain personally ensures each customized solution addresses your specific lawn concerns, whether it’s front-yard-only care, acreage management, or other unique lawn situations.
What if the weather interrupts my scheduled treatment?
Calgary’s weather can change suddenly—whether it’s unexpected rain, hail, or even snow. If weather interrupts your treatment, simply let us know, and we’ll promptly return at no extra cost. Your lawn’s health is our priority, and we never let unpredictable weather get in the way.
