Fiesta Weed Control: The Ultimate Guide

August 1, 2022

As we say goodbye to winter and hello to spring and summer, giving your yard a facelift may be at the top of your to-do list. The cold winter weather typically weakens your lawn’s health, drying it out and creating an environment in which weeds thrive. The result is an unhealthy and unsightly lawn when all the snow finally melts.

So, what are your options to bring your lawn back to life? Weeds and grass will battle for nutrients. Thus, one of the first steps is to eliminate pesky weeds to give your lawn a chance to flourish. One of the best ways to do this is to use weed control or pesticides. Fiesta® Lawn Weed Killer happens to be one of the best options on the market in Ontario.

If you’re wondering how this handy herbicide works, read on for our ultimate guide on Fiesta weed control.

What is Fiesta Weed Control?

First, we must answer the most basic question: what is Fiesta weed control? Fiesta weed control is a selective, post-emergent, broadleaf weed killer that eliminates weeds and leaves your lawn looking healthier than ever. In other words, Fiesta is a form of pesticide, which is any product, device, or substance that is manufactured and used to control, prevent, destroy, mitigate, or repel any pest. In this case, the pests are weeds.

Fiesta is a selective herbicide which means it will only kill certain plants – i.e. weeds – without destroying the rest of your lawn. Whereas a non-selective herbicide will destroy any plant matter it touches. It is important to note that Fiesta is also a contact herbicide rather than a systemic herbicide.

Systemic herbicides travel into the plant to leaves, stems, and roots. A contact herbicide does not move into the plant, so it is important to apply with full coverage in order to kill the weed.

What Can Fiesta Weed Control Be Used For?

Fiesta broadleaf weed control treats a wide variety of weeds and can aid in eliminating them from your gardens or grass. Examples of weeds that can be treated with Fiesta broadleaf weed control include but are not limited to:

  • Bull Thistle
  • Canada Thistle
  • Chicory
  • Dandelion
  • English Daisy
  • Moss
  • Thistle May
  • White Clover
  • Wild Chamomile

Since Fiesta can also be used as a spot treatment, it’s extremely easy to target these weeds without having to spray your entire lawn or garden with the pesticides.

Why is Fiesta Weed Control Used in Ontario?

There are very few pesticides that can be used on lawns and gardens for cosmetic use under Ontario law. Fiesta herbicide just so happens to be one of them, having been registered and approved for use in Ontario in 2010 by Health Canada’s Pest Management Regulatory Agency (PMRA).

The reason for Fiesta’s approval is because it was deemed a “low-risk” substance to use on lawns and in gardens. This is due to the fact that Fiesta is an all-natural, iron-based weed killer. If you’re wondering “Is Fiesta safe for humans?” or “Is Fiesta safe for pets?”, the answer is yes, as long as it is administered according to the directions on the bottle. The solution absorbs incredibly quickly (usually within three hours) and does not leave unpleasant odours.

That said, homeowners are still encouraged to put notice signs on their lawn. This will inform neighbours and passersby of the use of the substance.

Does Fiesta Weed Control Work?

We understand that you want to be confident that a product is going to work before you spend your hard-earned cash on it. We’re happy to report that Fiesta weed control works quite well when it comes to eliminating weeds.

The Fiesta iron solution absorbs super quickly and soon creates toxicity in broadleaf weeds. However, the iron solution has no harmful effect on your grass because broadleaf weeds handle iron differently than turfgrass. That means that using Fiesta will knock out the weeds without posing any threat to the quality of your grass, making it a win-win for people looking to spruce up their landscape. 

As you can tell from the table below, the efficacy of Fiesta in curbing the growth of weeds (in this case, dandelions) speaks for itself.

Can You Use Fiesta Weed Control in Cold Weather?

If you can’t wait until the spring or summer to start tending to your lawn, Fiesta weed control is effective even in colder weather. You can spray your first layer on your lawn or garden when the weather is still fairly cool, and you should start seeing noticeable results within a few days. From there, as the weather warms, you can apply more layers as needed. Spraying weeds when they are small tends to offer the best results.

How Is Fiesta Applied?

Fiesta typically needs to be sprayed by a licensed spray technician. The technician will spray the entire surface area that you want to be treated. The substance must then be absorbed, which usually takes roughly three hours before anyone can walk or play on the treated area.

How Often Should I Apply Fiesta?

It is recommended that you treat your lawn three times a year to maintain a healthy and beautiful lawn. You should aim to apply Fiesta in May and June to prepare it and sustain it for the summer months and then again in September to give it another dose before the cold winter months set in.

Where Can I Buy Fiesta in Toronto?

When it comes to where to buy fiesta weed control in Toronto, you’ve got options. Most hardware stores, such Home Hardware and Canadian Tire carry Fiesta weed control. You can also purchase the product from online retailers such as Amazon. However, if you are an unlicensed exterminator you can only purchase in small quantities.
