Alan Titchmarsh has revealed the only effective way to stop slugs and snails from destroying gardens. The esteemed gardener, broadcaster, and author shared his hard-won advice in Country Life magazine, stating that after trying every known deterrent, only one item truly works: copper rings.
The Problem with Slugs and Snails
Slugs and snails are a gardener's worst enemy, causing year-round damage that peaks in spring. These pests can devour rows of seedlings overnight, and mature plants are not safe either, as they shred leaves, stems, and flowers. Many natural and chemical remedies are suggested, but Titchmarsh has found most to be ineffective.
Deterrents That Don't Work
Titchmarsh dismissed metaldehyde-based slug pellets as inhumane, leaving slugs writhing in agony and posing risks to birds and wildlife. He also branded natural methods like crushed eggshells, holly leaves, sharp grit, gravel, and sheep's wool as unreliable and often a waste of time. Coffee grounds, another popular remedy, were deemed impractical and off-putting. He explained: "I do not drink enough Colombian or Arabica to carpet my hosta border in coffee grounds and, anyway, I'm not wild about imbuing my garden with an aroma redolent of Starbucks."
The Best Way to Stop Slugs and Snails
According to Titchmarsh, copper rings are the only effective deterrent besides hand-picking pests. He advises pushing a ring of copper into the soil around each plant to keep slugs at bay. He shared: "Apart from going out late in the evening and hand picking the pests (and lobbing them over the hedge onto the country verge), the only things that have worked for me are those rings of copper that resemble a vicar's clerical collar and which can be pushed into the ground around individual plants to discourage the molluscs from coming any closer. They are reputed (if kept clean) to impart a kind of electric shock to any slug or snail attempting to scale their dizzying height of 1in."
Protecting Potted Plants
For container plants, Titchmarsh suggests using pot feet as a simple deterrent. He notes that very few slugs and snails can scale large containers, making this an effective solution for potted plants.
