 As the name suggests, selective weed killers are designed only to kill a specific plant or weed.  

Lawn feed and weed killer is often your best bet for getting a weed-free lawn, as it only targets broadleaved plants (typically weeds) while avoiding narrowleaved plants like grasses at the same time.

Often the strongest of all herbicides, residual weed killers are also known as soil-acting weed killers. This means they kill everything, including the soil itself – leaving you unable to grow anything in it for weeks or even months afterwards.  

In general, people only use residual weed killers on paths or if you’re clearing your garden for paving or decking. 


Working only when they’re applied directly to the plant, contact weed killers have no effect on your garden’s soil – which is why they’re one of the best for removing lawn weeds before putting down your feed.  

The one drawback? As the weed killer must work its way into the plant while its photosynthesising, you have to time it right – apply early in the day, during the growing season. 


The opposite of selective weed killers, non-selective kills any plant matter it comes into contact with – so it’s best you only use this to remove weeds and scrub grass from your paths or walkways. This will ensure it won’t harm other healthy plants or your lawn at the same time.

Tackling your weeds from top to bottom, systemic weed killers work their way through the plant’s transport system to kill every single part of it. This means, if you apply systemic weed killer to a weed’s leaves, it will spread right the way down to the roots – so you can be sure you’ve attacked the whole plant at the same time. 


Sick of having to re-apply weed killers several times throughout the Summer? With a persistent weed killer, you can cut down on the effort – as they are designed to create a barrier that prevents weeds from returning for longer and new ones forming.  

Moss Killers

How do you tackle thick patches of moss in your lawn without damaging the grass alongside? With a moss-specific weed killer, of course.  

Targeting the dense green clumps on their own, moss killers can also come with added lawn feed and fertilizer to give your garden a helping hand at the same time. 


If you’ve got pets, you’re likely to be looking for a pet-friendly weed killer. Plenty of common garden weed killers are pet-safe, but only once they’ve dried fully – which can take a few days.  

If that’s not possible, there are several old-fashioned home methods you can try, from boiling water to diluted vinegar or salt. 


Glyphosate is the most widely used herbicide, as studies have concluded that it has a low toxicity for people. However, pets may be at risk of digestive issues if they touch or ingest plants that have recently been covered with this weed killer product. If you are worried about this chemical, non-glyphosate weed killers are a great option.  

Glyphosate-free weed killers are also more environmentally friendly as they don’t contain the same harsh chemicals as more traditional weed killers.
