Small amounts of leaves can be mulched by digging them into lawns and gardens. However,
leaves should not be raked or swept into the street because street sweepers cannot pick up large amounts of leaves. Leaves left in gutters can clog storm drains, leading to drainage problems and flooding after rain or snow storms.
In the fall, excess leaves can be recycled through the city's annual
LeafDrop program. Leaves that are collected are composted into soil that is available for free for any Denver resident.
