No offence intended but. If after aerating the lawn, you then upon mowing it, share it all with your neighbours, Then I wouls say that either you applied far too much top-dressing, and or. Your mower is set far too low. OR both. I believe that I posted a reply to another member a week or so ago, relating to top-dressing etc.
Particularly at this time of the year. Grass, remember your lawn is made up of thousands of tiny plants. Due in part to the soil condition following winter. The soil has clogged. To open it up, spiking assists this. Then using sharp sand, brushed in, the sand penetrates into the soil, assiting in surface drainage. The grass, now that it has started to grow again, plus the soil condition. The tiny grass plants begin to force themselves up and out of the soil. Top-dressing allows for a layer of soil to fill in and around the nodes of the plant. These nodes should always be just below the surface. In the event that the nodes do grow forth. Then sad to say. Along comes your mower and not only cuts the grass, but also severs the plant from the roots. I hope this helps.
