Whether you're looking to prevent those problem plants from popping up or your garden is slowly (but surely) being taken over, our collection of weed killers has you covered. 

Discover an array of lawn weed killers that'll tackle tough garden invaders with ease (right down to the roots - so you can be sure they won't return!) alongside hard surface weed killers to effortlessly rid your patios, drives, and decking of unwanted guests. 

And with every application method on offer, from liquid weed killers to weed killer granules (and even some nifty weed killer sprays!), you can be sure you'll find the perfect weed control products to suit your patch here.

Our range of garden weed killers even includes tree stump killers - an absolute essential for ensuring those deeply rooted plants are removed properly. Top tip: these are fantastic for saving your space from ivy before it takes hold! 

How long does it take for a weed killer to work?

The time it takes for a weed killer to work depends on the product and the type of weed being treated. Some herbicides provide visible results within hours, while others may take several days or weeks.

Is there a pet-friendly weed killer available?

Yes, there are pet-friendly weed killers on the market. Look for products that are labeled as safe for pets once dried. Additionally, consider natural alternatives like vinegar-based or corn gluten meal-based weed killers, which are generally considered pet-friendly.

How can I prevent weeds from growing in my lawn without using chemicals?

To prevent weeds without using chemicals, maintain a healthy lawn by regularly mowing at the appropriate height, aerating the soil, and overseeding with grass seed. Applying a thick layer of mulch in garden beds can also help suppress weed growth.
