what to do with grass clippings

June 27, 2026

You can treat grass clippings like a free, renewable garden resource rather than waste. They’re great for lawn health, mulching, compost, and even DIY fertilizer.

What to Do With Grass Clippings (Quick Scoop)

1. Easiest option: leave them on the lawn

Mow often enough that clippings are about 2–3 cm (around an inch) long. These small pieces fall between blades and decompose quickly.

They return nutrients (especially nitrogen) to the soil and can replace a big chunk of synthetic fertilizer over the season.

Rake or redistribute any thick piles so they don’t smother patches of grass.

Think of this as “grasscycling”: free fertilizer with almost zero effort.

2. Use as mulch around plants

Spread a thin layer (no more than a couple of centimetres) around vegetables, flowers, shrubs, or fruit trees to conserve moisture, cool the soil, and reduce weeds.

Let clippings wilt or dry for a day before spreading so they don’t mat, smell, or go slimy.

Keep a small gap around plant stems to avoid rot; top up periodically as they break down faster than wood mulch.

3. Turn them into compost “fuel”

Grass is a high‑nitrogen “green” that works best when mixed with “browns” like dry leaves, straw, shredded cardboard, or paper.

Alternate thin layers of clippings and browns and fluff the pile regularly for airflow to prevent bad odours and slime.

Finished compost (dark, crumbly, earthy smelling) is ideal for improving soil or as a rich mulch layer 5–7 cm thick.

4. Make DIY “grass tea” fertilizer

Fill a bucket about one‑third full with fresh clippings, then top with water and let it steep 3–5 days, stirring now and then.

Strain and dilute the liquid roughly 1:1 with fresh water, then apply at the soil surface or as a gentle feed around plants.

Use this occasionally as a quick nutrient boost alongside your usual compost and mulches.

5. Line paths and suppress weeds

Let clippings dry, then spread a thin layer on garden paths, between stepping stones, or between veggie rows to block light and slow weeds.

Re‑apply as they decompose; over time they build organic matter in walking areas that may become future beds.

Avoid using fresh, thick layers on paths, which can turn slick and messy when wet.

6. Build raised beds and new garden areas

Use clippings as part of a layered (“lasagna” style) bed: coarse branches or sticks at the bottom, then alternating layers of grass, leaves, straw, compost, and topsoil.

As the grass layer rots, it feeds soil life, improves structure, and boosts fertility in new beds over time.

Don’t overload with thick, wet layers or you risk creating a compact, smelly, low‑oxygen zone.

7. Seasonal tips & safety notes

Spring: Lush clippings are perfect for compost or light mulching in new plantings.

Summer: Dry them first for path cover or weed suppression; they’re also valuable left on the lawn to help retain moisture.

Fall: Mix with fallen leaves for an ideal compost balance of greens and browns.

Winter: Store dry clippings in breathable bags for early‑season mulch or layer into new beds before frost where winters are mild enough.

Important cautions

If your lawn was treated with herbicides or certain weed‑and‑feed products, let clippings decompose separately for a few weeks before using in compost or around sensitive plants.

Avoid using seedy, weedy clippings as mulch in places where you don’t want those weeds spreading.

Mini forum‑style take

“I used to pay to haul my clippings away. Now they’re the backbone of my compost and mulches, and I barely buy fertilizer anymore.”

Using these approaches, “what to do with grass clippings” turns from a disposal problem into a steady, free stream of nutrients and soil‑building material for your yard and garden.
