A gardening expert has advised against throwing used tea bags straight into compost heaps due to the presence of microplastics. Simon Akeroyd, known for his horticultural tips on TikTok, explained that many tea bags are made from materials that do not decompose.
Instead, he recommends tearing open the bags, allowing the leaves to dry, and then sprinkling them around the base of plants. The dried tea leaves contain tannins that can help deter slugs and snails, while also providing nutrients and acting as a soil conditioner.
Fellow expert Christopher O'Donoghue of Gardens Revived confirmed the issue, noting that modern tea bags often contain polypropylene seals and may be treated with chemicals. He advised checking packaging to ensure bags are compostable if used in compost heaps.
The advice has been well-received on social media, with followers expressing gratitude for the eco-friendly tip. Both experts stress that only fully biodegradable tea bags should be composted directly.
