Birmingham residents dumping garden waste are being warned they could be fined £2,500.
Warning stickers have appeared on abandoned bags of green waste and letters are being sent to suspected tippers.
In February, the Labour-controlled city council introduced a £35 annual fee for garden waste collection.
Previously covered by council tax, the charge followed a £2m reduction in the city's waste budget as part of a £102m cuts plan.
