Slugs will leave your garden if you use one forgotten Victorian gardening trick that works wonders. For hundreds of years, gardeners have been coming up with the best tips and tricks to help their outdoor spaces thrive. One annoyance that nearly every gardener has experienced is the struggle of keeping pests away. They can do serious damage to plants, and steps need to be taken to deter them. 

This handy gardening trick has been used since the 1800s, and it will keep slugs out of your garden, experts say. Slugs are an unwanted pest in your garden and can feed off of plants you want to thrive, including flowers, vegetables and herbs. Many people opt for chemical pesticides to deal with their slug problems. However, you can save time, money and your plants by preventing the slugs from arriving into your garden in the first place. 

Lena Wren teamed up with Heat Pump Covers to share the clever hack. She recommends that gardeners bury open top glass bottles in their outdoor space. 

This might seem rather random, but it is a trick that has been proven to be effective for generations of gardeners. She explains that it produces a humming sound that turns the slugs away. 

Us humans would barely notice it but creatures under the ground certainly will. She says: "It creates a subtle vibration through the soil. Moles and even slugs pick up on it and move away. It unsettles them without doing any harm."

Wren says that gardeners can use any kind of glass bottle that has a narrow neck, such as a lemonade bottle or a wine bottle. She advises to bury them halfway into the ground, ideally near areas under threat from these pests. 

Along with this hack, Wren has a a few more suggestions for gardeners when it comes to keeping pests away from their plants. One of her top tips is to use onion peels or coffee grounds to throw off pests' sense of smell, which attracts them to your garden plants. 

She also suggests planting crown imperial flowers, which are known for their strong scent. Wren explains: "It’s about creating an environment that tells pests: you’re not welcome here."
