Please discard it in the trash. The number one thing you don’t want to do with an old garden hose is put it in the recycling bin. It can muck things up. In the recycling world, garden hoses are what are known as “tanglers.” Tanglers include hoses, along with ropes, chains, and cords.
A single tangler can cause a massive disruption for recycling facilities, potentially resulting in safety issues for workers and mechanical issues for machinery. All this leads to downtime and extra expense in facilities across the nation.
