The frequency of mowing should decrease unless we experience an extended warm/dry spell and the height of cut can be raised gradually to between 6mm (¼”) and 12mm (½”) above the summer height.

If the underlying soil is heavy and firm, start to hollow core (spiking with hollow tines), followed by top-dressings using Inturf Premium Soil.

Bulk top-dressings should be applied evenly with an appropriate machine (if the garden exceeds 500 square metres) or by hand and brushed into the sward. NB: Avoid smothering the grass too much!

Coverage on average should be roughly one bag of Inturf Premium Soil per 100 square metres, varying the amounts depending on any depressions or irregularities in surface levels.

It is advisable to add a mixture of Inturf Classic Seed in with the top-dressing material in order to increase the population of grass in any worn areas.

Repeat the process as described earlier in the year.

Worms may become active again at this time of the year. If this is a problem, treat the area with a proprietary brand of worm killer, although cultural methods are just as effective such as brushing, switching and regular good management.

Light rolling may be useful, but only if absolutely necessary and if there are no visible worm casts, which can smother the grass if rolled.

It will no longer be necessary to scarify the area, apart from maybe a light raking to remove worm casts and providing this has been undertaken on a fairly regular basis throughout the spring and summer. NB: Heavy scarification now may cause too much damage and the grass will only recover next spring!

An application of Inturf Establish Fertiliser can be made towards the end of the month. This will provide the nourishment the grass needs and harden the grass plants, making the grass less susceptible to disease.


Regular mowing gradually comes to an end, although when weather conditions are suitable, mow the area as frequently as demanded by the length of growth.

Keep the area free from debris and leaves and try to use this month to “rest” the area in readiness for the winter months.

A further smaller application of Inturf Establish Fertiliser may prove useful to really harden the grass plant off for the winter months.

Make sure there is at least four weeks between your September and October applications of Inturf Establish Fertiliser.


During frost-free and fairly dry periods this month, mow the area as and when necessary – the blades now set at their highest level.

Always remove debris from the surface to help prevent disease.
