Yes aeration is the key,we aim to solid tine the greens with the Toro pro core at least once a month.
It's helps with drainage,puts new oxygen to the roots which is vital to healthy turf.
As far as the moss I use a soluble iron which dries the moss out and then scarify to pull it out.The aim of the game is to keep the dew off the grass as that's where moss and disease thrive so brushing and switching the dew off the turf will help prevent it ?
