Best Strong Weed Killer Reviews UK
Gardening is a great pastime for many people in the UK. While the wet weather may limit our time in the garden, those that do get the reward of seeing all their hard work bloom into a beautiful garden teeming with plants, flowers, trees and more.
Of course, if there is one thing that anyone hates about gardening it is the weeding. Weeds are a highly invasive form of plant that quickly spread around every garden. They take up valuable soil space, fighting with plants for nutrients, sunlight, and growing space, making them a huge nuisance that a lot of work to remove.
Anyone that’s weeded before will know it can be a back-breaking task that takes hours to complete, and even then, it only works as a temporary solution as the weeds are going to keep growing back.
Plus, the bigger the garden the more wees you’re likely to have. They aren’t selective either, growing in almost every outside area of a home, including lawns, flower beds, vegetable boxes, pots, planters, handing baskets, and in and around paths, driveways, and gravel.
There’s almost no area of a garden that isn’t invaded by weeds and they can certainly ruin the appearance of the space, not to mention potentially limiting the growth of our plants and flowers.
This is where weed killers come into play. Available for almost every type of weed, weed killers are usually liquid solutions that are applied directly to the weed to kill it. These contain any number of chemical ingredients that kill a part of the weed or the entire plant.
There are also weed killers that can be used before weeds have the chance to develop, working pre-emptively to ensure not weeds grows in an area you’re planning on using.

Weedol Pathclear Weedkiller Liquid Concentrate
As the name suggests, the Weedol Pathclear is weed killer designed for quick and easy application around pathways and driveways. Consisting of several tubes of concentrated glyphosate, the weed killer is simple to use – just add a tube to a litre of water and apply to the weeds.
Each tube provides enough weed killer to cover an area of roughly 20sqm, so a couple of tubes should be enough to eliminate weeds from most average UK gardens. The fact you just add the contents to water makes it simple to use, avoiding the hassle of measuring your own precise solution.
One drawback is that because most people use it in a watering can is that it won’t have the most accuracy, especially if applying to areas with lots of plants you don’t want to harm. If you want more accurate application then it’s a good idea to invest in a spray bottle!
That said, the weed killer is designed for simple use on paths and driveways, which is where the watering can is the best method of application, as it has a wide area of coverage and you can easily apply it to wider areas with lots of weeds and no plants.
As a systemic weed killer, it works to kill both the foliage and roots of the plant. This takes several weeks to fully kill off the weed, although you can see visible results in just a few days.

This weed killer from Deadfast consists of 12 concentrated sachets that can be either applied directly to a weed or diluted with water for a wider coverage. A single sachet mixed with water offers a good coverage too, with enough liquid weed killer to cover an area of up to 60sqm.
Using a single sachet on a weed is also possible, although you won’t get anywhere near the same level of coverage. Still, there are instances where you may require a potent weed killing solution to remove a particularly stubborn weed – think large growths of brambles or even on a tree stump to kill it off.
If you have a large area with lots of weeds, such as a patio or driveway, then these sachets really come into their own. Simply add the sachet to watering can or spray bottle and apply the weed killer accordingly.
The results may take some time to appear initially, with the weed killer taking around 1-2 weeks to fully work its way through the outer extremities and into the weed system. Bigger weeds may take even longer, so always be patient and give the weed killer time to work, as it may take up to 4 weeks for complete contorl to happen.
Also, be mindful that rainfall can reduce the effectiveness of the weed killer, so if it rains within six hours of application you may need to apply a second dose to kill the weeds.

This means it’s easy to get confused with all the weed killer options available for UK gardens. To make the process easier, check the buying guide below for all the info you need to purchase the best weed killer for your garden:
Weed Killer Types
There are several types of weed killers with various ingredients that produce different results. So, it helps to know what type of products are available and their main uses, as you can choose something that meets your own requirements.
Pre-Emergent and Post Emergent
Broadly speaking there are two main types of weed killers, known as pre-emergent and post-emergent. As the names suggest, these are used either before or after the weed has emerged from the ground.
The most common weed killers in the UK are all post-emergent, so if you already have weeds to deal with then go for this option. Pre-emergent are good for preventing growth in the first place, so can be used as you’re sowing and planting early in the growing season.
A contact weed killer will kill the plant after contacting it. These are probably the most common types found in spray bottles, where you just apply it to the weed and wait for it to die. They tend to have quick results but they may not be long-lasting, mainly because the chemicals only attack the above soil portion of the plant.
In most instances, contact weed killer starts working in a just a few hours, with notable wilting occurring shortly after application. The weed will remain for a few weeks before dying off completely.
These weed killers are much more powerful than contact killers although they are applied in the exact same way, spraying the above soil part of the plant. The main difference is that the chemicals are then absorbed by the weed foliage and transported throughout the root system.
This kills the entire weed, including the roots, to ensure that no future growth is possible. Unlike contact killers, systemic weed killers take longer to kill the weed, often taking several weeks before results appear.
Systemic weed killers are useful for those hardier weeds that take more effort to remove by hand, such as dandelions, thistle, and brambles.
Selective and Non-Selective
All the above mentioned weed killers are categorised as either selective or non-selective. As the name suggests, selective weed killers work on certain types of weeds while non-selective killers kill off almost anything it comes into contact with – that includes plants, grass, flowers, fruits and vegetables!
Selective weed killers are suitable for things like lawns and flower beds where you don’t want to risk killing off anything but the weed. Non-selective weed killers are highly effective but also risky to use near other plants as they kill plants indiscriminatel, so should be used with more care and precision.
Tips for Choosing the Right Type of Weed Killer
Now that you know the types of weed killer available you will have a better idea of what you might need for your garden. Check out some of these tips to help you choose a suitable weed killer:
What type of weeds are you dealing with in the garden? If it’s tough perennial weeds such as dandelions, yarrow, or creeping buttercup then you may require a systemic weed killer, while annuals may be manageable with a contact killer
Also, note whether there are multiple types of weeds or a large volume of a single type. If it’s a lot different weeds then be sure to choose a non-selective killer!
Check to see where the weeds are located in your garden and choose a suitable weed killer. For instance, if it’s on your lawn then you will want a selective weed killer to ensure the grass doesn’t die.
Furthermore, there are weed killers designed for certain locations. For example, patio and driveway weed killers are useful for killing offer weeds appearing between cracks, gravel, and similar areas.
Also, be mindful of their location in relation to other plants you have. If you’re controlling a flower bed or vegetable patch then you will want to choose a selective weed killer that won’t damage your plants.
Remember, weed killers use a combination of chemicals that are often dangerous to touch, so always check to see how safe they are to use and whether there are certain instructions you need to follow.
Many are safe for dogs and children, meaning they won’t cause damage if anyone touches the area shortly after application. Be mindful that stronger weed killers may be more toxic, so always take the time to read the safety information before you buy.
