Artificial Grass Care in Autumn: How to Keep Your Artificial Lawn Clean, Fresh and Ready for Winter
As summer comes to an end and the weather begins to change, your artificial grass needs a slightly different kind of care.
Autumn brings falling leaves, increased rainfall, cooler temperatures and more organic debris into the garden. While artificial grass doesn’t require mowing, feeding or reseeding like a natural lawn, regular artificial grass care in autumn can help prevent odours, drainage problems and unwanted build-up before winter arrives.
At GreenBlade, we recommend using autumn as an opportunity to give your artificial lawn a thorough clean and establish a simple maintenance routine for the wetter months ahead.
Why does artificial grass need more attention in Autumn?
Artificial grass is designed to be relatively low maintenance, but it isn’t maintenance-free.
During autumn, several things change at the same time:
- Leaves and organic debris begin falling onto the lawn.
- Rainfall becomes more frequent.
- Gardens receive less sunlight.
- Artificial grass can remain damp for longer.
- Mud and dirt can be carried onto the lawn.
- Pet urine and organic contamination can continue accumulating beneath the surface.
This combination makes autumn an important time for artificial grass maintenance.
Removing debris and keeping the surface clean helps your lawn continue looking its best while reducing the organic material that bacteria can feed on.
For households with dogs, autumn maintenance can be particularly important because rain doesn’t necessarily remove the source of artificial grass odours.
Does rain clean artificial grass?
One of the biggest misconceptions about artificial grass is that autumn rain will naturally clean it.
Rain can rinse loose surface dirt from artificial grass, but it shouldn’t be considered a replacement for proper cleaning.
This is particularly important where dogs regularly use the lawn.
Dog urine can travel through the artificial grass fibres and into the layers underneath. Depending on the installation and drainage system, residues and bacteria can remain present even after heavy rainfall.
In some gardens, rainfall can actually make an existing smell noticeable again as dried organic residues become wet.
If your artificial grass smells worse after rain, the problem may therefore be contamination within or underneath the grass rather than something sitting visibly on the surface.
1. Remove fallen leaves regularly.
One of the simplest things you can do for your artificial lawn during autumn is remove fallen leaves before they accumulate.
A few leaves aren’t a problem.
However, a thick layer of wet leaves can trap moisture against the surface and eventually begin decomposing.
This creates organic debris that can contribute to:
- Unpleasant smells
- Dirt and residue
- Moss or organic growth around problem areas
- Reduced drainage
- A generally dirty-looking lawn
Use a suitable artificial grass brush, plastic rake or leaf blower to remove leaves without damaging the grass fibres.
During periods of heavy leaf fall, checking the lawn every few days can prevent a much bigger cleaning job later.
2. Brush your artificial grass.
Regular brushing helps keep artificial grass looking upright and well maintained.
Over summer, garden furniture, paddling pools, children’s toys, pets and general foot traffic can flatten areas of the lawn.
Autumn is a good opportunity to brush the fibres and remove loose debris.
Brush against the natural direction of the pile using a suitable artificial grass brush. Pay particular attention to frequently used paths and areas around doors, furniture and children’s play equipment.
Brushing also makes it easier to spot areas that may require deeper cleaning.
3. Give your artificial grass an autumn deep clean.
The transition from summer into autumn is an ideal time to properly clean your artificial grass.
During warmer months, your lawn may have accumulated:
- Dust
- Food and drink spills
- Pet urine
- Pet waste residue
- Dirt
- Pollen
- Organic debris
- Bacteria and odour-causing contamination
A specialist artificial grass cleaner can help remove contamination rather than simply masking unpleasant smells with fragrance.
GreenBlade artificial grass cleaning products have been developed specifically with artificial lawns in mind, providing homeowners with a straightforward way to maintain cleaner, fresher outdoor spaces.
For general seasonal maintenance, clean the entire lawn rather than only treating areas that visibly look dirty.
4. Pay extra attention to artificial grass used by dogs.
If you have dogs, your autumn artificial grass routine should include regular cleaning of the areas they use most frequently.
Dog urine can pass through artificial grass, which is exactly what a correctly installed lawn is designed to allow.
However, urine residues and organic contamination can accumulate within the installation over time.
This is why simply spraying the lawn with water may not completely solve persistent smells.
The amount of cleaning required will depend on several factors, including:
- Number of dogs
- Size of your dogs
- Size of the lawn
- How frequently the lawn is used
- Base material underneath the artificial grass
- Drainage
- Existing contamination levels
If you’re unsure which cleaning approach is right for your garden, use the GreenBlade Odour Index Calculator to assess your lawn and identify the most appropriate cleaning solution.
5. Check your artificial grass drainage before winter.
Autumn is also an excellent time to pay attention to drainage.
Artificial grass should allow rainwater to drain through the surface, but leaves, soil and organic debris can interfere with drainage around the lawn.
After heavy rainfall, look for areas where water remains standing for unusually long periods.
If you notice persistent puddles, check for obvious surface blockages first.
Where drainage problems continue, the underlying installation may need investigating.
Dealing with drainage problems during autumn can help prevent them becoming more noticeable during prolonged periods of winter rain.
6. Clean up after atumn storms.
Strong winds and heavy rainfall can quickly deposit leaves, twigs, soil and other debris onto an artificial lawn.
After particularly bad weather, give the garden a quick inspection.
Remove larger debris and check corners, edges and areas around garden furniture where leaves tend to collect.
A five-minute clean after a storm is much easier than dealing with several weeks of decomposing leaves later.
7. Don't ignore artificial grass odours before summer is over.
Artificial grass odours are often associated with hot summer weather because heat can make smells much more noticeable.
That doesn’t mean the underlying contamination disappears when temperatures fall.
If your artificial grass smelled of dog urine during summer, autumn is the perfect opportunity to tackle the source before winter.
Covering the smell with heavily fragranced household products may temporarily make the garden smell fresher, but it doesn’t necessarily address the contamination responsible for the odour.
Using a cleaner specifically intended for artificial grass is a much better addition to a regular maintenance routine.
How often should you clean artificial grass in Autumn?
For most households, there isn’t one cleaning frequency that works for every garden.
A lightly used artificial lawn without pets may simply need regular debris removal, occasional brushing and periodic cleaning.
A smaller garden used by several dogs may require much more frequent cleaning.
The best cleaning schedule depends on how your artificial grass is actually being used.
As a general autumn routine:
Every few days:
Remove excessive fallen leaves and obvious debris.
Weekly:
Inspect high-traffic and pet areas and remove any contamination.
Regularly throughout autumn:
Brush the lawn and use an appropriate artificial grass cleaner when required.
After heavy rainfall or storms:
Check for debris, drainage issues and returning odours.
The important thing is consistency. Small amounts of regular maintenance can prevent much larger problems developing.
Can you pressure wash artificial grass?
Pressure washing isn’t normally necessary for routine artificial grass maintenance.
Excessive pressure can potentially disturb the grass, infill or installation depending on how the lawn has been constructed.
For everyday autumn maintenance, brushing, debris removal, rinsing where appropriate and using a specialist artificial grass cleaner is usually a more controlled approach.
If you’re considering pressure washing an artificial lawn, always check the recommendations provided by your grass manufacturer or installer first.
What's the best artificial grass cleaner for Autumn?
The right artificial grass cleaner depends on the problem you’re trying to solve.
For general seasonal maintenance, you may simply need a product designed to clean and freshen the surface.
For gardens regularly used by dogs, however, you may need a solution designed to tackle the organic contamination associated with pet urine and persistent odours.
This is why GreenBlade doesn’t believe artificial grass cleaning should necessarily be a one-product-fits-every-garden process.
Your lawn, pets, installation and contamination level all influence what it needs.

Frequently asked questions about artificial grass in autumn.
Do leaves damage artificial grass?
Leaves won’t normally damage artificial grass simply by landing on it. However, allowing large quantities of wet leaves to remain on the lawn can create organic build-up and trap moisture. Regularly removing fallen leaves is therefore recommended throughout autumn.
Why does my artificial grass smell when it rains?
Rain can rehydrate residues and organic contamination already present within an artificial lawn, making existing smells noticeable again. This is particularly common in gardens regularly used by dogs. Cleaning the source of the contamination is generally more effective than simply trying to cover the smell.
Should I clean artificial grass before winter?
Yes. Autumn is an excellent time to thoroughly clean artificial grass. Removing summer contamination, leaves and organic debris before winter can make ongoing maintenance much easier during colder and wetter weather.
How do you remove leaves from artificial grass?
A leaf blower, suitable artificial grass rake or stiff non-metallic brush can be used to remove leaves. Avoid equipment that could cut, tear or excessively pull at the grass fibres.
Does artificial grass need maintenance in winter?
Artificial grass still benefits from basic maintenance during winter. Remove debris, clean contamination when necessary and periodically check that drainage areas remain clear.
What should I use to clean artificial grass after dog urine?
For artificial grass regularly used by dogs, choose a specialist artificial grass cleaner designed for pet-related contamination and odours. The correct product and cleaning frequency will depend on factors including the number and size of dogs, lawn size, installation and severity of contamination.
