Seasonal Lawn Care: Autumn
After a long summer of family barbecues, children playing, and long dry spells, your lawn is likely looking a little tired. Autumn is the 'golden window' for lawn recovery. The soil is still warm from the summer sun, but the frequent autumn rain provides the perfect conditions for grass to repair itself before the harsh winter weather arrives.
At Online Turf, we have been farming turf for two decades, and over this time we have learnt exactly what your lawn needs to recover from summer stress and survive the winter ahead.
Here is our practical, step-by-step guide to autumn lawn care.
1. Clear the Leaves
It sounds simple, but keeping your lawn clear of fallen leaves is one of the most important parts of autumn lawn maintenance.
If leaves are left to sit on the grass, they block out vital sunlight and trap moisture against the turf. This creates a damp, suffocating blanket that encourages lawn diseases, such as snow mould, to thrive. Rake your leaves regularly and add them to your compost bin; your grass needs to breathe!
2. Scarify to Remove Thatch and Moss
Over the summer, a layer of dead grass, moss, and organic matter, known as thatch, naturally builds up at the base of your lawn. While a tiny amount of thatch is fine, too much of it acts like a sponge, stopping rainwater and nutrients from reaching the roots.
Autumn is the perfect time to scarify your lawn:
- For small gardens: Use a spring-tined rake and pull it vigorously through the grass to rip out the dead moss and thatch.
- For larger lawns: Hire or buy a mechanical scarifier. Work in straight lines up and down the lawn, pushing the blades just a few millimetres into the soil.
Note: If you have laid new turf this year, skip this step. You do not need to scarify a lawn in its first year, and doing so can damage the establishing roots.
3. Aerate to Fix Soil Compaction
Heavy summer foot traffic compacts the soil beneath your grass, squeezing all the oxygen out of the ground. Aerating is the process of spiking holes into the soil to relieve this pressure, allowing oxygen, water, and nutrients to reach the deep root system. Read our blog for more on aerating and scarifying.
You can use a garden fork to puncture holes 4–5 inches deep across the lawn, wiggling it slightly to lift the earth. If your soil is heavily compacted clay, use a hollow-tine aerator to pull physical plugs of soil out of the ground. This instantly improves drainage and stops your lawn from becoming a waterlogged mud bath in November.
Does Your Lawn Need a Complete Fresh Start?
If your lawn is more than 50% weeds or moss, autumn is the perfect time to replace it. The warm soil and frequent rain make it the easiest time of year to lay fresh, farm-grown turf.
We harvest our turf the day before delivery, guaranteeing a fresh, weed-free finish.
4. Repair Bare Patches (Overseeding)
Once you have scarified and aerated, your lawn might look a little bare. This is entirely normal, and it is actually the perfect time to thicken it up.
Overseeding involves spreading fresh grass seed over your existing lawn to fill in the gaps before weeds can take over. Scatter a high-quality mix, such as our Rye Gold® Lawn Grass Seed, evenly across the thin areas. Then lightly brush a thin layer of Enriched Topsoil over the seed to protect it from hungry birds and provide a nutrient-rich bed for germination. Keep the area moist, and the autumn rain will do the rest of the hard work for you. For more information on over seeding read our blog.
5. Apply an Autumn Lawn Feed
If you want to give your grass a fighting chance against frost and snow, you need to apply a specialised autumn lawn feed.
A common mistake is using leftover spring fertiliser in October. Whilst not a major issue, it's better to use an autumn feed as it's formulated to aid the plant at this time of year. Spring feeds are high in nitrogen to encourage rapid leafy growth, which is the exact opposite of what you want right now. Instead, you need a winter-specialised formula that is high in potassium and iron. This hardens the grass blades, strengthens the roots, and helps prevent winter diseases without forcing the grass to grow too fast.
6. Adjust Your Mowing Height
As the temperatures drop and daylight hours shorten, your grass will naturally stop growing as fast.
Raise your mower blades to a higher setting for your final few cuts of the year. Leaving the grass slightly longer (around 2 inches) provides more surface area for the blades to absorb weak autumn sunlight, helping the plant store energy for the winter.
Remember to only mow when the grass is dry to avoid tearing the blades and damaging your mower! Read more on our mower blog.
