With spring fast approaching, many gardeners are preparing to revive their outdoor spaces, but one persistent pest threatens their efforts: slugs. However, former royal gardener Jack Stooks has shared an effective, natural method to rid gardens of these slimy invaders without harming other wildlife.
Jack, who spent over 20 years working in the royal gardens at Highgrove Estate, recommends using the leaves of the brassica family, like cabbage, and cauliflower, as a simple yet powerful slug trap.
Jack advised placing brassica leaves in the corners of growing patches, weighed down with a rock or another sturdy object. By checking these daily, gardeners can expect to find up to five or six slugs beneath each leaf.
Once collected, the slugs can be disposed of in an eco-friendly manner, either by handpicking them off or placing them in beer traps, which humanely eliminate them.
For those seeking a more long-term solution, Jack suggests using copper slug collars.
These reusable, flexible barriers create an effective deterrent, as the copper emits a mild electric charge that slugs refuse to cross. While not lethal in all cases, it significantly reduces their movement and ability to feed on plants.
Slug pellets remain one of the most common pest control methods, but Jack cautioned against their use due to their impact on pets and wildlife.
While organic slug pellets are available, he believes they do not work as effectively as other natural solutions.
“If you’re looking for an easy, natural way to keep slugs at bay, brassica leaves are a fantastic trick that anyone can try. For a more permanent fix, copper collars offer excellent protection without harming the environment,” Jack said.
By following these expert tips, gardeners can protect their plants and keep their gardens slug-free this season without resorting to harmful chemicals.
