I would clear a layer of whole leaves before it settles into a wet blanket over the grass. A few scattered leaves are a different matter, and a light fall can sometimes be chopped with a suitable mower. The useful distinction is whether the grass is still exposed to light, or sitting underneath a covering that stays put.
Look at the grass underneath, not just the number of leaves
A lawn with green showing between loose leaves is very different from a corner where broad leaves overlap like roof tiles. Lift a handful from that corner. If they come away as a damp sheet, I would put that patch first on the list.
Leaves intercept the light the grass needs. A persistent covering can weaken it, which is why the RHS recommends clearing fallen leaves from lawns in October. Waiting for every tree to finish dropping leaves can leave the earliest-covered patches underneath for too long.
I would prioritise the shaded side of the garden, sheltered corners where leaves collect, and any recently repaired patches. Do not judge the whole lawn from the open middle. The part tucked against a hedge may need attention while the rest looks quite clear.
- A few loose leaves, plenty of grass showing: no need to chase every one immediately. Check again after wind or rain.
- Overlapping leaves that conceal the grass: collect the bulk when the ground is fit to work on.
- Fine chopped fragments sitting between the blades: these may be left on an established lawn, provided they are not forming a layer over it.
Can you mow the leaves instead of raking them?
Yes, in the right conditions. On established grass, a suitable mower can chop a light scattering of dry leaves finely enough for the pieces to settle between the blades. University of Minnesota Extension explains this leaf-mulching approach; the practical point is to deal with a modest amount regularly, rather than attempting a deep covering.
I would only do it when the lawn is firm enough for mowing and the leaves are dry enough to break up. Follow your mower’s instructions for mulching. Do not remove its collection box and assume that makes it a mulching mower: the correct plug, discharge arrangement and blade depend on the machine.
Try a short strip first and look back. You want visible grass with small fragments disappearing into it. If you have left a brown coating or clumps on top, collect them. More passes over a soft lawn are a poor trade for saving a little raking.
Keep the cutting height appropriate for the grass; do not scalp it to reach the leaves. Where your mower is suitable for collecting leaves, the collection box offers another route: gather the chopped material instead of leaving it behind. Pick up sticks and other debris first.
New grass needs a gentler approach
If you have recently overseeded or repaired bare patches, give those areas extra attention. Small grass shoots can be hidden by just a few broad leaves, but a vigorous rake can pull them out as well.
For a small patch, I would pick the leaves off by hand, working from the edge where possible. Avoid dragging a heap across it. A blower is not automatically gentler: a strong blast can move loose seed and the surface material around it. Young grass is also not ready for a mower simply because the neighbouring lawn is.
If the repair itself still needs doing, my guide to repairing bare lawn patches in autumn explains how to judge the remaining growing opportunity. Keeping leaves off an existing repair is useful even when it is too late to start another one.
Make collecting leaves easier on a small lawn
Start with a light leaf rake and a collection bag or wheelbarrow close by. Use gentle strokes to draw leaves together; this is a surface tidy, not scarifying. Work in small sections so you are not dragging the same pile the full length of the garden.
For clearing customers’ gardens, I use broad leaf grabbers to load the bags: they lift far more loose leaves than my hands alone and are light enough to keep beside the bag.
I would use these handheld leaf grabbers for leaves and light clippings. Plastic paddles can flex under a heavy load, so take smaller scoops of wet leaves and keep soil and substantial branches out. They still involve bending; if that is difficult, check a long-handled option rather than buying handheld paddles for the wrong reason.
For a larger garden, my leaf blower or garden vacuum guide covers when a powered tool earns its space. I would sort out the collection point first whichever tool you choose.
What if the lawn is too wet to walk on?
If your boots leave deep impressions or water squelches underfoot, postpone walking a heavy bag or mower across it. The RHS also advises avoiding lawn work in waterlogged or frosty conditions.
Lift what you can safely reach from a path, then return when conditions improve. Avoid creating a muddy route with repeated trips to the same collection point.
Keep some leaves for the rest of the garden
Clearing the lawn need not mean stripping the whole garden bare. Leaves have a useful place beneath hedges and in suitable, undisturbed areas, where they provide shelter for wildlife. Keep them off paths and avoid burying small plants or piling wet material against their crowns.
Collected leaves can also become leaf mould. If storage is the awkward part, my bags versus wire cage guide helps you choose a place for them. The RHS leaf-mould guide explains how moisture and air help the process along.
