A Slugglish Year: A Challenging Year for UK Gardeners

This year has been particularly tough for UK gardeners due to an unprecedented surge in slug and snail populations. The combination of a mild, moist spring and a cool start to summer has created the perfect environment for these slimy pests to thrive.

Unprecedented Slug Activity

With hundreds of slugs species in the UK, not all are plant eaters. However, the wet weather has led to a dramatic increase in slug activity, causing significant damage to gardens, balconies, and fields. Social media is flooded with complaints and cries for help as gardeners seek effective ways to combat these persistent pests. One user lamented, “They’ve decimated my tomatoes and peppers. Hate the slimy demons.” Slugs and snails are particularly active when it’s mild and damp and the very wet summer has created optimal conditions for hem.

Overwhelmed Garden Advice Services

The RHS’s garden advice service has been inundated with inquiries about slugs. “We saw a huge peak in slug inquiries in March, April, and May,” Salisbury notes. Many gardeners are initially unaware that slugs are the culprits behind the damage and seek guidance on prevention and control.

Lewis Normand, president of the Royal Caledonian Horticultural Society, highlights the impact on vegetable growers, mentioning that “courgettes, squash, and young tomato plants have been particularly affected.”

Slug Damage on Balconies and Farms

Slugs are not limited to ground-level gardens. “It’s amazing how high they can actually climb,” Salisbury observes. Slugs leave telltale slime trails even on walls, sometimes reaching rooftops.

In agriculture, slugs are a major pest, particularly the grey field slug (Deroceras agreste), which targets young crops. Tom Allen-Stevens, founder of the British On-Farm Innovation Network (Bofin), states, “The damage that slugs do is very, very early on in the crop’s life. They’re actually a nightmare.”

Sustainable Control Measures

While some gardeners turn to traditional methods like eggshells, grit, and pellets, these are often not scientifically proven to be effective. Salisbury advises against using salt due to its cruelty and potential soil damage. Instead, natural solutions such as ponds, which attract slug-eating amphibians, and introducing leaf litter to encourage predators like hedgehogs, can be effective.

Farmers consolidate soil to eliminate slug hiding spots, a method that may not be as effective in smaller garden spaces. Normand suggests trapping slugs in jam or beer in half-buried jars and warns against using toxic slug and snail killers. For those with ducks or chickens, these animals can significantly reduce slug populations.

Embracing a Balanced Approach

Ultimately we should allow some tolerance and acceptance of some slug damage and balance in the garden ecosystem. Normand agrees, preferring to pick slugs and snails off plants by hand, embodying a pragmatic approach to dealing with these persistent pests.

Gardening can be a game of win or lose when it comes to dealing with slugs. By adopting a mix of traditional, natural, and innovative methods, gardeners can mitigate the impact of these slimy invaders while maintaining a healthy and balanced garden ecosystem.
