Lady has a lawn that has been taken over by moss. 50% of the lawn is straight moss. 25% is more moss then grass. 25% is more grass then moss. I have talked about the need to remove the moss, thin and remove trees, soil test, aerate, all must be done before reseeding. About 15,000 SF of lawn. I know moss will lift of easy with a rake or a BP blower where there is no grass. Will using a power rake/thatcher make the job to remove the moss that much faster/easier? Any other ideas?
