Prepare Your Lawn for Autumn

How to Prepare Your Lawn for Autumn

As summer fades and cooler days arrive, your lawn needs a little extra attention to stay healthy through autumn and into winter. Taking a few simple steps now can make all the difference, ensuring your grass bounces back strong in spring.

1. Keep Mowing, But Adjust the Height

Don’t put the mower away just yet! Grass continues to grow during autumn, but at a slower pace. Keep mowing until growth stops, and gradually lower your cutting height to around 2.5–3 cm. This prevents the grass from matting under fallen leaves and helps it resist disease.

2. Rake Away Fallen Leaves

A blanket of autumn leaves may look beautiful, but it smothers your grass, blocks sunlight, and traps moisture—ideal conditions for fungi. Rake regularly or use a leaf blower to keep the lawn clear. You can also add leaves to your compost pile for an eco-friendly bonus.

3. Aerate the Soil

Compacted soil prevents air, water, and nutrients from reaching grass roots. Autumn is the perfect time to aerate, either with a garden fork or an aerator tool. Aeration encourages deeper root growth, preparing your lawn to withstand the cold months ahead.

4. Feed with a Seasonal Fertilizer

Summer growth can deplete your lawn’s nutrients. Apply a slow-release autumn lawn feed rich in potassium and phosphorus (rather than nitrogen). These nutrients strengthen roots and boost disease resistance, setting your lawn up for winter survival.

5. Overseed Thin Patches

If you notice bare or thin areas, overseed them in autumn. The cooler weather and increased moisture create ideal conditions for grass seed to establish before winter. Lightly rake in the seeds and water well to encourage germination.

6. Control Weeds and Moss

Weeds and moss can take advantage of weaker grass in autumn. Use a suitable weed killer or moss control product, or simply remove them by hand. A strong, healthy lawn is the best long-term defense against these invaders.

7. Water If Needed

Autumn usually brings more rain, but don’t assume your lawn is getting enough moisture. If it’s a dry spell, water occasionally to help new grass seed establish and keep roots strong.

Final Thoughts

Preparing your lawn in autumn is all about resilience—helping it store energy, strengthen roots, and resist the challenges of winter. With just a bit of effort now, you’ll be rewarded with a lush, green lawn when spring returns.
