Weed Control (Fiesta®)

Fiesta® is a low-risk, iron-based herbicide (FeHEDTA) that specifically targets broadleaf weeds while leaving your grass untouched. Fully compliant with Ontario’s strict cosmetic pesticide laws, it’s one of the few proven legal options for residential lawns in Toronto and across the GTA.

Odour-free, pet-friendly, kid-safe, and pollinator-friendly once dry, Fiesta® is the perfect choice for a healthy, beautiful lawn without compromising your environment.

"Smart Weed Control for a Cleaner Lawn!"

How Fiesta® Weed Control Works?

  • Quick Absorption

    The iron solution is absorbed through weed leaves within minutes.

  • Cell Damage & Collapse

    Excess iron ruptures plant cells, causing foliage to darken and wither.

  • Visible Results

    Wilting often begins the same day, with full damage visible within a week.

  • Rain-Fast in 3 Hours

    Sudden showers won’t wash it away, making it ideal for unpredictable GTA weather.

Application Philosopy at
GREEN & BRIGHT SOLUTIONS

We rely on precise spot-spraying for most visits—targeting only visible weeds with accuracy and efficiency. This method helps conserve product, reduce over-application, and keeps your lawn looking clean and consistent.

It also allows for easy repeat treatments throughout the season, focusing only where weeds persist. Spot-spraying becomes especially important during hot or sunny weather, as it helps avoid temporary bronzing of grass blades that can sometimes occur when Fiesta® is applied in high temperatures—ensuring great results without compromising the appearance of your lawn.

On cooler or overcast days (below 27 °C), we may apply a full coverage spray across the lawn to reach hidden or developing weeds beneath the turf canopy.

What You Can Expect?

  • Professional touch – applications are done carefully, leaving no mess or obvious spray marks.
  • Minimal disruption – safe to walk on the lawn once dry, usually within a few hours.
  • Clear check-ins – after each visit, you’ll notice exactly where treatments were applied.
  • Visible contrast – weeds quickly darken and wilt, while your grass stays healthy.
  • Season-long weed control – with regular visits, you'll see fewer weeds and a more even, healthier-looking lawn.

Important Realities:

  • Not Preventive — Fiesta® treats existing weeds; it won’t stop new seeds from sprouting.
  • Multiple Visits Needed — Persistent or creeping weeds often require follow-up treatments to fully suppress.
  • Realistic Results — Even the best legal product can’t promise perfection, but Fiesta® remains one of the most effective options available in Ontario.
  • Lawn Care Partnership — Proper mowing and watering boost Fiesta®’s results and help your lawn resist future weeds naturally.

Beyond Weed Control: Building a Healthier Lawn

Weed control is only half the story. The healthiest lawns come from a strong foundation— thick turf, deep roots, and consistent care.

By pairing Fiesta® treatments with professional fertilization, liquid aeration, pH balancing using lime, or improving compacted soils with gypsum, and compost topdressing, you create an environment where weeds simply can’t compete. Check out our plans and pick the one that fits your lawn best.

Need a chemical-free option for delicate areas? We also offer manual weed removal for gardens, patios, walkways, and sensitive turf zones.
