Should I Remove Leaves From My Garden Beds?
Fallen leaves can be useful landscape material. The goal is to manage them, not automatically haul every one away.
A completely bare garden bed may look tidy, but fallen leaves are not automatically waste. CSU Extension encourages using leaves in the landscape because they return organic material to the soil and can function as mulch.
The useful question is not 'Should every leaf go?' It is 'Is this amount and type of leaf cover helping this bed?'
A light layer can be useful
Shredded leaves can help insulate soil and newly planted material. Leaves also break down into organic matter over time. In windy Colorado Springs yards, shredding them first makes them less likely to migrate to the neighbor's porch by the next afternoon.
When cleanup makes sense
- A thick, wet layer is matting down and blocking air or water movement.
- Leaves came from plants with a significant disease problem and sanitation is part of managing that disease.
- The leaves are burying small evergreen groundcovers or other plants that need light and air circulation.
- Accumulated dry material creates an unwanted fuel bed close to a structure.
Use what the yard already produced
Leaves can also be chopped with a mower before being moved into appropriate beds or compost. The goal is to keep a useful resource on site where practical rather than treating every autumn leaf as trash.
