Natural Slug Deterrent Using Kitchen Scraps
Growing your own vegetables can be tremendously satisfying, with even modest crops delivering a decent yield for your dinner table. Common choices that tend to be straightforward to cultivate include salad leaves, greens, courgettes, peas, or strawberries, but the challenge is that slugs adore them too.
Within just a few hours or during the night, slugs and snails can demolish thriving young plants down to mere stems, leaving your vegetables damaged and frequently unable to recover. These troublesome garden intruders will also devour a crop of ripe strawberries before you have the opportunity to harvest them yourself.
While slugs play a vital role in the ecosystem as numerous birds and other creatures feed on them, outdoor areas can become infested with these gastropod pests, wreaking havoc for gardeners. Specialists warn that slug pellets, including organic varieties, can prove detrimental to wildlife in your gardens, but assistance is available through kitchen waste items.
How Eggshells Work as a Slug Barrier
Eggshells have been discovered to be successful at discouraging slugs from your garden crops. It's a proven technique where gardeners wash then crush the eggshells and place them at the base of vulnerable plants. The eggshell approach helps to stop slugs from reaching the fruit and foliage of the plant.
Some gardeners who have experimented with this technique have left the eggshells in halves, creating a substantial sharp-edged barrier surrounding the plant, and this has demonstrated effectiveness. Slugs dislike navigating over the jagged edges, and that's precisely why it works at keeping them at bay. However, following rainfall, the eggshell technique can prove less reliable as the shells become slippery.
Additional Natural Methods from RHS
The Royal Horticultural Society (RHS) has outlined another natural approach that may also prove effective in keeping slugs away from your vegetables. On their website, RHS reported: 'Traps, such as scooped-out half orange, grapefruit, or melon skins, can be laid out cut side down or jars part-filled with beer and sunk into the soil near vulnerable plants. Check and empty these regularly, preferably every morning.'
These natural traps will lure the molluscs away from your edible crops, allowing salad leaves, vegetables, and strawberries to flourish without being devoured.
Biological Control: Nemaslug
There is also a biological control method available that poses no threat to other wildlife in your garden or outdoor space. 'Nemaslug' is an organic solution comprising microscopic worms that can be watered directly into the soil. These worms, known as nematodes, penetrate the slugs' bodies and infect the slimy gastropods with a bacteria that triggers a fatal disease.
Gardeners are also urged to scatter coffee grounds in the garden in June as an additional deterrent. By combining these natural methods, you can protect your vegetables without harming the environment.
