Many gardeners face the challenge of maintaining a healthy, vibrant lawn while also keeping plant-eating pests away. While chemical treatments can be costly and sometimes harmful to the environment, there’s a clever, low-cost alternative that could help solve both problems. Used teabags are humble kitchen scraps that just end up in the bin, but they could also be the secret to a stronger, greener lawn, as well as a natural pest repellent, all for less than £1.
According to gardening expert Chris Ware from Climbing Wild Gardeners, teabags are packed with tannic acid and nutrients that enrich the soil. He explained: “Tea bags contain beneficial compounds that improve soil structure, retain moisture, and provide plants with essential nutrients.”
This makes them a great natural fertiliser, particularly for lawns, offering a cost-effective and eco-friendly alternative to chemical treatments.
“Tea bags are especially beneficial for lawns,” Chris advised. “Burying used tea bags just beneath the soil’s surface helps retain moisture and supports healthy root growth.”
This simple trick can also reduce fungal infections, resulting in a greener and healthier lawn over time.
And, if that wasn’t enough, beyond their fertilising properties, teabags also serve as an effective natural defence against pests.
“The strong scent of tea is unappealing to slugs and snails, making it an effective deterrent,” Chris noted.
By placing used teabags around flower beds and vegetable patches, gardeners can help keep these destructive pests at bay and even discourage cats and foxes from digging up gardens.
Chris also suggested covering the tea bags with a light sprinkling of soil to hide them while still benefiting from their repellent properties.
A box of 80 Stockwell tea bags from Tesco costs just 90p, and a box of 40 PG Tips tea bags from Sainsbury’s costs £1.70, making this an affordable option for any gardener looking to improve their garden’s condition.
Teabags aren’t the only household waste that can benefit your garden. Chris also recommends banana peels as a natural fertiliser.
“Banana peels are rich in potassium, calcium, and phosphorus, which support plant growth and fruit production,” he said. By chopping them up and burying them near plant roots, you can boost your plants’ resilience and support overall plant health.
