As spring arrives, flowers bloom, and plants flourish, but with this also comes the arrival of pests. Pests, including slugs, are more prominent in spring, especially when the weather is humid.
Liam Cleary, gardening expert at Old Railway Line Garden Centre, said: “Pests are an unavoidable part of gardening, but there are plenty of ways to protect your plants and your hard work without relying on chemical deterrents.” According to the expert, planting fragrant herbs like lavender and basil can help to keep bugs away from the garden. Liam explained: “Their strong aroma overwhelms pests’ sense of smell, discouraging them from sticking around in search of food.
“Not only does this protect your plants, but it also safeguards the environment by reducing the pollution caused by insecticide use.”
1. Lavender
Whilst we might think the smell of lavender is relaxing and pleasant, pests find it overwhelming.
Plant it in a sunny spot with well-draining soil. Since lavender thrives in dry conditions, do not overwater it and fertilise sparingly.
2. Basil
According to the pro, Basil can help deter several pests, including slugs and mosquitoes.
Plant basil in a sunny spot with well-draining soil. Since it thrives in warmer temperatures, consider starting it indoors and transferring it outside in the summer.
3. Rosemary
The gardening expert continued: “Rosemary releases a strong, woody scent from its essential oils, which many insects find unpleasant, causing them to avoid it.
“Plant rosemary in a sunny spot with well-drained soil. It thrives in full sun and doesn’t like wet roots, so water it sparingly and prune to maintain its shape.”
4. Mint
While we enjoy mint’s many benefits, insects find its strong menthol scent horrible, making your garden “extremely unpleasant.”
Mint is happy in full or partial sun, but make sure to water it well, as it prefers moist soil, especially in the summer.
5. Catnip
Liam said: “Catnip contains a chemical called nepetalactone, which triggers a pain receptor in many insects, causing a stinging sensation when they come into contact with the plant. This deters them from landing nearby.
“Choose a sunny spot and plant catnip sparingly in moist, well-draining soil. After initial growth, occasionally pinch back the stems to encourage growth.”
