I have been raking the lawn everyday this week, and there were so much moss coming out every day. The lawn is patchy with lots of moss taken out, and also looks brown. I looked closely into the lawn, and there are some normal grass, but most of them are thatch and moss. Why is this happening? It used to be like that in the past but not as bad as this year. What could be causes fir this situation, and what would be best way to deal with the problem? Thanks.
