Apply lawn feed - use a fertiliser with a high phosphate content. In late summer it is not advisable to apply a high nitrogen fertiliser to a lawn as it will promote vigorous growth which will not stand up to the rigours of winter. Fertilisers with high phosphate content will instead promote root growth which will toughen up the grass for winter.
