Weed control in Ontario isn’t as straightforward as it once was, but that doesn’t mean a healthy lawn is out of reach. It just requires a different approach—and a little teamwork.
A lush, green lawn has numerous environmental benefits. However, since the government banned traditional weed control products in Ontario, managing weeds has become more challenging. The good news? By following proper mowing, watering, and seeding practices, you can still maintain a strong, resilient lawn that naturally suppresses weeds. Here’s what you can reasonably expect when it comes to weed control services in Ontario.
How Long Does Weed Control Take to Work?
Before the legislation changes, weed control treatments took about 3-5 days to show results. With Fiesta, the government-approved natural alternative, the process now takes approximately 10-14 days.
After each application, you should see an initial reaction fairly quickly—many weeds will start to blacken around the edges. However, not all weeds absorb the product at the same rate. Giving the treatment its full time to work will maximize its effectiveness.
More Treatments Aren’t Always Better
It might seem logical to apply more product for faster results, but that’s not always the best strategy. The amount of weed control product used—and the timing of applications—are crucial to long-term success.
At Dr. Green, we follow Integrated Pest Management (IPM) guidelines, meaning we apply the right amount of product at the right time for the most effective results. Over-applying can make weeds resistant to the treatment, making them even harder to manage. It also has environmental consequences, which is why we apply only what’s needed to achieve lasting results.
Weed Management vs. Weed Prevention
It’s important to understand that the natural weed control products approved in Ontario manage existing weeds—they do not prevent new weeds from growing. The product must be absorbed through the leaves of an existing weed and travel to the root system to suppress regrowth. The longer the distance between the leaves and roots, the longer the product will take to work (e.g., dandelions take longer to respond than clover). Keeping your lawn regularly mowed improves the effectiveness of each weed control treatment.
The best preventative measure for weeds? Regular seeding.
Why Seeding is Essential for Weed Prevention
Weeds thrive in bare or thin areas of your lawn. The more space they have, the more they multiply. To combat this:
- Seed bare areas in both spring and fall to thicken your lawn.
- Overseed the entire lawn once per year to ensure new grass growth and minimize open spaces where weeds can take hold.
- Set your mower blade to 2.5 – 3 inches and mow regularly. Taller grass develops stronger roots, which naturally outcompete weeds.
Final Thoughts
We understand that weeds are a concern for our customers (and for us too!). However, successful weed management requires patience and consistency. With regular treatments, good lawn care practices, and teamwork, you’ll see a significant reduction in weeds over the season.
