Leaving cucumber chunks in the garden this autumn can help protect plants from slugs and snails, according to a chemical-free farm founder. The simple, non-chemical method draws the pests away from crops such as lettuce, which they find more appealing than the cucumber.
Slugs and snails are a common problem for gardens, feeding on plants like lettuce, hosta, dahlias, and zinnias. Damp weather can make the situation worse, and many gardeners may notice silvery slime trails, nibbled seedlings, or vanishing leaves after autumn downpours.
The Cucumber Hack
Barrie Quinn, founder of Portnoo Market Garden, a small, chemical-free farm, shared the trick on Instagram. He described it as "simple" yet "super effective" and said he wished he had tried it sooner. In his video, Quinn shows a bed of lettuce he is trying to protect from slugs. He places chunks of cucumber around the edges because, as he explains, "slugs love cucumber" and "they're attracted more to it than the lettuce."
Quinn advises that it is better to use cucumbers that are past their best. He added, "[The slugs] will gather all in one place, and all you've got to do is relocate them away from the plants they're eating. Super effective. Non-chemical. Perfect."
How the Method Works
The technique works similarly to companion planting or using trap plants. The cucumber slice acts as a lure, drawing slugs and snails in with its appealing scent and moisture. While it won't eliminate the pests completely, it can help keep their numbers down.
Moving Slugs Away
When relocating slugs and snails, it is advisable to take them at least 20 to 30 feet away from the garden, ideally further. The greater the distance, the less chance they have of finding their way back. For best results, consider moving them 50 feet or more, or to a completely different area, giving the creatures a chance to settle elsewhere while keeping plants protected.
