How The DIY Works Team Tests & Rates The Weed Killers

Whether you go to your local gardening store or shop online, you will find that there are hundreds of weed killers to choose from. However, to help you find the best, we’ve carried out plenty of testing and hours of research.

Types of testing we’ve carried out included using weed killers on lawns, block paving driveways and many other common locations. We also tested weed killers that came in a spray bottle such as the Roundup Fast Action as well as super strong glyphosate formulas that we applied to the weeds via a pump sprayer as shown in the photos below.

Below is a video that we posted on our YouTube channel that shows us testing a glyphosate-based formula that we diluted and applied using a pump sprayer. As you can see in the video, the application is very easy and we simply pressurised the sprayer using the pump and used the wand to direct the formula into its intended location.

To give you an idea of how fast weed killers take, below are day-by-day results after applying a glyphosate weed killer. As you can see from our testing of the product, it had proven to be very successful and after raking away the dead weeds, the patio area was weed-free and no further weed killing was necessary.

Some of the factors that we considered included their strength, ease of application, effectiveness on all types of weeds, coverage and value for money.

The Best Weed Killers

At DIY Works, our content is 100% independent and we would never recommend a product that we wouldn't use ourselves (read our editorial standards and how we test products).

1. Best Overall: Roundup Fast Action

(How We Review →)

By far the most popular and highly rated weed killer is the Roundup Fast Action. This particular example is a “Pump ‘N Go” option but the brand offers the formula as a refill bottle, trigger spray bottle and a pull-out trigger spray bottle.

According to the brand, it’s designed to kill weeds and their roots with visible results in just 1 to 2 days. This can be achieved with a single application and upon a range of areas such as paths, drives, patios, fences and much more.

  • Ready to use solution
  • During testing, we really liked the extending wand design that made spraying the formula directly onto the weeds much easier
  • Provides up to 10 minutes of continuous spray
  • Child and pet friendly once dry
  • Leaves no harmful residue
  • Contains 7.2g/l of glyphosate to give it the extra power
  • Comes in a large 5 litre bottle that can be refilled
  • Relatively expensive when compared to other weed killers

Although expensive, the Roundup Fast Action in this clever “Pump ‘N Go” bottle is one of the best ready-to-use weed killers on the market. The popularity speaks for itself and it certainly won’t disappoint wherever it’s used.

2. Most Powerful: Rootblast Glyphosate Weed Killer

(How We Review →)

If you want to not only tackle but destroy deep-rooted weeds in your garden, patio or driveway, look no further than the Rootblast Super Strength weed killer. This is because it’s a concentrated formula that contains a large amount of glyphosate and promises effective results on all types of weeds.

According to the brand, when mixed correctly, you can expect a coverage of approximately 1666m2 from just 1 litre.

  • Commercial strength formulation with 360 g/l of glyphosate
  • During testing, we found it to be effective on all types of weeds
  • Penetrates deep into the soil to kill weeds at the root
  • Easy to mix and dilute to the manufacturers guidelines
  • Comes with protective gloves
  • If sprayed on your lawn, it'll also kill the grass
  • Requires a pump sprayer and mixing with water

To conclude, the Rootblast formula is the best weed killer on the market if you require maximum strength for killing all types of weeds. The high concentration of glyphosate means that it’ll easily kill brambles, ivy, horsetail and many other weeds but it’s important to note that you should avoid using it near your lawn as it will kill the grass too.

3. Best For Lawns: Weedol Concentrated Lawn Weed Killer

(How We Review →)

Another popular weed killer is by the reputable Weedol brand and this formula in particular is their weed killer for lawns, which is ideal for killing dandelions, daises and clovers. According to the brand, it contains no glyphosate and is designed to kill weeds and not your lawn.

In terms of using this lawn weed killer, you will want to pour the concentrated formula into a sprayer or watering can. You can then treat any weeds on your lawn without worrying about it killing off the grass.

  • Supplied with mixing instructions for application via sprayer or watering can
  • 500 ml concentrate formula treats up to 333m2
  • Breaks down in soil and is child and pet friendly once dry
  • Only requires a single application
  • Results within 2 to 4 days
  • Won't kill weeds at the root

To conclude, the Weedol Lawn Weed Killer is a high-quality and easy-to-use formula that is by far the best option for lawns. It’s important to note that for the best results whilst using this weed killer, it’s recommended that you use it between April and September.

4. Best Weed & Feed: Miracle-Gro Complete 4 in 1

(How We Review →)

If you wish to kill weeds on your lawn as well as feed it simultaneously, Miracle-Gro’s Complete 4-in-1 is a great option to consider. We’ve already rated it as one of the best moss killers for lawns in another roundup and it’s a product that we highly recommend for keeping your lawn healthy as well as moss and weed free.

  • Promotes a healthier and greener lawn
  • During testing, we found it to be very effective as killing weeds on our lawn
  • Kills moss as well as weeds
  • Easy to apply by hand or using a spreader
  • As a standalone weed killer, it would be difficult to target certain areas as you ideally need to treat your entire lawn

If you want to treat your entire lawn, the Miracle-Gro Complete 4-in-1 is the perfect solution. Not only does it kill weeds but it’ll also tackle the dreaded moss and make your grass thicker and greener too. During testing of this product, we used a garden spreader and we would highly recommend it to ensure that the granules are evenly spread.

5. Best For Driveways: Job Done Path Weed Killer

(How We Review →)

It’s not just your garden that’s prone to weeds because your driveway and in particular block paving unfortunately enjoy their presence too. Luckily, there are many dedicated formulas that are designed for patio and driveways that not only kill the weeds but also helps to prevent them from reappearing too such as this Job Done Path formula.

According to the brand, their weed killer destroys all types of weeds in less than 24 hours and protects against new weed growth for up to 3 months.

  • Specifically formulated for driveways, patios and paths
  • Very effective on all types of weeds (even deep-rooted weeds)
  • During testing, we didn't notice any weeds reappear during the 3 month period
  • Available in a 1, 2.5 or 3 litre bottle
  • Ready to use formula
  • 3 litre bottle comes with a trigger for easier application
  • Not suitable for lawns
  • Relatively expensive when compared to other weed killers

For tackling driveways, paths and patios, the dedicated Job Done formula is a great option to consider. Unlike other weed killers, this formula also benefits from the added 3-month protection to keep your driveway weed-free for longer.

6. Best Value: Resolva 24H Ready To Use Weed Killer

(How We Review →)

The Resolva 24H is another very popular and highly-rated weed killer and one of the main reasons for this is its budget-friendly price tag. With bottle sizes that start from 1-litre to 5-litre power pump bottles, there are plenty of options to choose from but if you require a cheap weed killer for a small number of weeds, the 1-litre bottle is more than adequate.

In terms of using this weed killer, it’s best used upon paths, patios or driveways and it’s able to kill off even the toughest of weeds that other ready-to-use solutions may have struggled with.

  • Visible effects within 5 minutes and it'll kill off any weeds within 24 hours
  • Available in multiple bottles sizes
  • Option of a power pump bottle and refills
  • Breaks down naturally in the soil
  • Developed by a reputable brand
  • The trigger on the spray bottle can become quite tiresome to use if you are spraying a lot of weeds at once

To conclude, the Resolva 24H ticks all the boxes and is an affordable weed killer that certainly won’t disappoint. Whether you are tackling grasses, docks, nettles, dandelions, bindweed or other types of weeds, you should see visible results fast and any weeds should be killed off within 24 hours.


Weeds can be a big problem in gardens, patios, driveways and various other areas around your home and they also come in a variety of different types. However, controlling them with any of our recommendations is relatively straightforward.

For the best results, you’ll want to use the formulas as they are growing, which is usually around mid-spring time. If you don’t want to use any chemicals to kill off weeds, you may want to do some research into electric weed killers as they can be very effective because they use fire to instantly burn the weeds in a matter of seconds.
