Hedge shears don't necessarily need to be hung, but hanging them is a good practice for several reasons:

1.Protection: Hanging your hedge shears on a wall hook or tool rack helps protect the blades. It keeps them off the ground, preventing contact with moisture, soil, and debris that can lead to rust and damage.
2.Accessibility: Hanging your shears in a designated spot makes them easily accessible when you need them. This convenience can save time and effort when you're working in the garden.
3.Organization: Hanging your hedge shears along with other garden tools on a tool rack or pegboard can help keep your gardening area organized. It allows you to see and access your tools more efficiently.
4.Safety: Hanging tools out of reach, especially if you have children or pets, helps prevent accidents. Sharp garden tools like hedge shears can pose a safety risk when left lying around.
5.Space-Saving: Hanging tools on a wall or rack can save valuable floor space in your garden shed or garage, helping you make the most of your storage area.

While hanging your hedge shears is a recommended practice, it's not an absolute necessity. If you choose not to hang them, make sure you store them in a clean, dry place, use a protective cover or sheath to shield the blades, and regularly inspect and maintain them to prevent rust and ensure they remain in good working condition.
