September Lawn Advice

Here are Will’s Norfolk Lawns top 6 September lawn tips.

Autumn Fertiliser

 Between September-November is a good time to consider applying a low-nitrogen, autumn fertiliser to your lawn. It is likely your lawn has been under some drought stress during the summer months due to high temperatures and low amounts of rainfall. Applying a specific autumn fertiliser will give your lawn a much needed boost whilst preparing the plants for the colder, darker months of the upcoming winter.

Although temperatures might be gradually dropping, your lawn should still receive a cut every 7-10 days. Remember, the best approach is little and often. Ensure you keep your mower blade sharp and avoid taking off anymore than 1/3rd of the length of the grass during any one cut. Regularly change the direction you are mowing and aim to mow between 25-40mm in height.


 Autumn is a great time to scarify your lawn to remove thatch and dead grass/organic matter. Lawn Scarification will remove unwanted and potentially harmful thatch and moss from your, promoting a healthier, thicker grass coverage. Doing so along with some over-seeding will encourage a thick grass coverage for the winter ahead, allowing your lawn the best chance as possible to remain healthy through into next year.


Aeration is one of the most important practices to be carried out on any turf surface. If your lawn hasn’t been aerated for some time, we advise planning to do so between September-December.

Repair Work

If you have any areas within your lawn that has suffered throughout the summer, now is a great time to repair those patches. Rake over the area to remove any dead grass, moss or thatch. Spike the surface with a garden fork and sow seed into the soil and cover with a thin layer of soil or compost. Any areas of your lawn that are left thin or bare during the autumn and winter months are likely to be taken over by moss and weeds, so it is vitally important to keep a good grass coverage.

Garden Furniture

It is likely that during the summer you have been enjoying the sun, soaking up the rays on some garden furniture in your garden. Remember, once you have finished with the furniture remove them from your lawn. Leaving them on the surface for prolonged periods will cause the grass beneath them to die off.
