A Simple Cardboard Method for Autumn Weed Control
As the gardening season transitions into autumn, horticulturists are sharing a straightforward technique for managing weeds that requires little more than discarded cardboard. The method, endorsed by specialists at uk, works by blocking sunlight from reaching weed growth, a principle explained by the experts at the plant retailer.
Chris Bonnett, horticulturist and founder of GardeningExpress, discussed the challenge weeds pose during warmer months. "Weeds can be really frustrating throughout summer, as plenty of sunlight helps them photosynthesise and grow rapidly," he said. Bonnett also noted that weeds are "often an eyesore and, even worse, can take away nutrients from the plants you actually want to grow in the garden."
Step-by-Step Guide to the Cardboard Technique
The advice shared across several regional outlets is straightforward. Gardeners are advised to cut cardboard to fit the specific area of concern and to remove any plastic tape, labels, or stickers, as these materials do not biodegrade. The cardboard should then be laid flat on the ground, ensuring it fully covers the affected area and is pressed down securely to prevent gaps.
When dealing with areas larger than a single piece of cardboard, the experts recommend overlapping sections by approximately 15cm. This overlap is critical to prevent weeds from finding gaps and pushing through toward the light.
Once the cardboard is in position, a layer of mulch or compost can be applied over it. This layer serves multiple purposes: it helps hold the cardboard in place, improves the visual appeal of the area, and retains soil moisture. The combination also facilitates the natural breakdown process.
The cardboard is then left in place, gradually decomposing over a period of months, as described by the specialists at Somerset Live and other local outlets.
Environmental and Soil Benefits
Beyond weed suppression, the technique offers additional advantages for soil health. Bonnett highlighted the eco-friendly nature of the method, saying, "Using leftover cardboard is an eco-friendly method that allows you to recycle old boxes while helping the soil as the cardboard naturally decomposes."
As the cardboard breaks down, it contributes organic matter to the soil. Bonnett explained that after a few months, the material begins to decompose "benefiting the soil as 'brown' matter," which helps create what he described as "a healthier growing environment for the rest of your plants."
The advice arrives as many gardeners contend with persistent weeds during the growing seasons. Bonnett acknowledged the wide range of weed-control products and techniques available, but cautioned that some methods, particularly chemical ones, can cause problems elsewhere in the garden. He added, "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."

Facts Included:
The plant experts at uk say cardboard is ideal for weed suppression because it blocks sunlight.
Cut a piece of cardboard to fit the space and remove any plastic tape or stickers, as these are non-biodegradable.
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.
Once the cardboard is in place, cover it with a layer of mulch or compost.

AI-extracted; can misattribute a claim — see Methodology.
Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status is Contested when two claims on this page negate each other; otherwise it counts the mastheads we found asserting that specific claim — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
