How to mulch or remove lawn leaves
Shred a manageable layer of leaves into the lawn, or collect them when they form a mat. The finished grass should be visible through small leaf pieces, not hidden under a blanket.
What you need
Rotary mower suitable for mulching, its approved blade and mulching plug, rake, tarp or collection bags, and suitable eye, hearing and dust protection.
Step by step
- Choose mulch or collect. A loose layer that the mower can shred is suitable for mulching. Rake or collect a wet mat, deep piles, or leaves over delicate seedlings. Do not start with a deep layer just because a trial mulched several inches successfully.
- Clear obstacles. Pick up sticks, stones and litter. Check leaf piles for animals before disturbing them. Keep bystanders away from the mower’s working area.
- Set up the mower. Use the approved mulching configuration and your grass’s normal cutting height. Do not lower the deck to get under the leaves. Isolate power before changing parts or clearing a blockage.
- Make a slow pass. Take a partial-width bite if the mower struggles. Avoid forcing heavy wet material through the deck.
- Inspect the result. Small pieces should settle between grass blades. Make another pass at an angle if needed. Stop mulching and collect excess if the grass remains hidden, the mower clogs or pieces gather in clumps.
- Clear edges and leftovers. Rake or collect material the mower cannot reach. Move it to a tarp or suitable bags. Keep leaves out of drains and the street.
- Use or dispose of collected leaves. Shredded leaves can mulch beds, kept away from plant stems, or go into compost or a leaf-mould bin. Follow local collection rules. Do not dig a thick layer of fresh leaves into a planted bed.
After the job
Check the lawn after the next rain or leaf fall. Rake out any remaining mats. A thin, evenly distributed layer of shredded leaves can remain; it does not need routine collection.
Continue mowing while the grass grows, at a height suitable for its species. At the last visit before winter, clear smothering cover but do not cut every lawn down to 2 inches.
Keep normal nutrition appropriate to the grass. Leaf mulching is not a reason to automatically add extra nitrogen.
Make leaf mould
Put leaves in a ventilated wire bay or suitable pierced bags, moisten dry material and leave it to break down. Shredding helps. Check occasionally that it is damp rather than waterlogged. Use it when decomposed enough for the intended job; leaf mould for a fine lawn topdressing needs to be well broken down and screened.

Common questions
Can leaves stay on the lawn?
A light scatter or finely shredded layer can stay if grass remains visible. Remove thick or wet mats that cover and shade the turf.
Should I cut lower to mulch leaves?
No. Keep the cutting height appropriate for the grass, slow down and take a narrower bite. Collect material the mower cannot shred effectively.
