Weeds not only spoil the look of a well-kept outdoor space, but they can also damage the structure of paths and driveways over time. While many turn to quick-fix solutions like white vinegar or boiling water, these methods are often short-lived and can even be harmful to surrounding plants.

The good news is that there’s a far more effective, long-lasting way to deal with these persistent weeds. And the best part? It requires just one simple item that a gardening enthusiast swears by.

Forget harsh chemicals and kitchen remedies – the most effective method is using a paving knife.

This handy tool is specifically designed to get into the narrow gaps between slabs, hooking out roots and cutting away weeds with precision.

Unlike vinegar or salt solutions, which may only kill the visible top growth, a paving knife allows you to target the entire weed, roots and all.

It also helps prevent damage to nearby plants and soil – a win for eco-conscious gardeners. Better still, it’s a once-and-done approach that keeps weeds from returning as quickly.

A gardening expert at Thrive – The Society for Horticultural Therapy – recommends a hand tool over chemical approaches wherever possible, especially in hard-to-reach areas like patios.

"Using a paving knife or similar hand tool is one of the best ways to remove weeds between paving slabs, as it allows you to get right into the cracks," says the expert.

"Pulling the whole plant out by the root is much more effective than simply killing the top with vinegar or boiling water."

Once weeds are removed, the gaps can be brushed clean and even filled with kiln-dried sand to slow future growth of weeds.

For larger paved areas, a long-handled version of the paving knife can help to prevent back pain from bending over too much in the garden. 

Pairing regular weeding with proper maintenance means your patio stays tidy all season long – without needing to resort to chemical sprays.

So before reaching for vinegar or weedkiller, consider this expert-approved, low-cost tool that can remove weeds without harming nearby plants.
