I intend to kill lawn moss. May I leave the dead moss on the lawn to rot? Unsightly, I know, but I recall you dealing with this some tome ago
Raking or scarifiying helps but is a lot of work.
The grass should be given lawn feed to boost its growth and the moss, if left, will not be noticed.
If the grass is very thin after moss killing, and raking, lawn seed can be over-sown.
