If there is a problematic area of weeds, cut a piece of cardboard to fit the space and remove any plastic tape or stickers, as these are non-biodegradable. Then lay the cardboard flat on the ground, ensuring it completely covers the affected area and is pressed down securely to prevent any gaps.

If smaller pieces of cardboard are all that are at hand, overlap them by around 15cm to stop weeds creeping through the edges to reach the sunlight. Once the cardboard is in place, cover it with a layer of mulch or compost which helps hold the cardboard down as well as improving its appearance and retaining moisture in the soil, allowing the cardboard to break down naturally.

The cardboard should then be left in place to suppress the weeds while gradually decomposing and adding organic matter to the soil. Chris Bonnett, horticulturist and founder of GardeningExpress said: “Weeds can be really frustrating throughout summer, as plenty of sunlight helps them photosynthesise and grow rapidly.

“They are often an eyesore and, even worse, can take away nutrients from the plants you actually want to grow in the garden. There are many tricks and tips out there to get rid of or prevent weeds, but some can actually cause problems for the rest of your garden, especially when chemicals are involved.

“Using leftover cardboard is an eco-friendly method that allows you to recycle old boxes while helping the soil as the cardboard naturally decomposes. Laying cardboard over problematic areas helps suppress weeds by blocking out sunlight, which is crucial for them to grow.

“After a few months, the cardboard will also begin to decompose, benefiting the soil as ‘brown’ matter, helping to create a healthier growing environment for the rest of your plants.”
