You should not need more then one application of Moss-Out per year ...

De-thatching should be done if moss/thatch is thicker then one inch and only if
moss/thatch is killing the grass plants.

Lawns can be alot of work. If you have money, have someone else do the work.

Good morning to the group here. Very nice forum.

I have an older lawn that suffers from moss. I've trimmed out trees (at
considerable expense) but I haven't done a pH test nor have I aerated yet.
I have run a dethatching rake over the area but it seems to remove too much
of the good grass too.

Next, I put down a moss reducing application from a hose-end sprayer. I'm
not sure if I used enough. Anyway, my question is if the moss dies out,
will I need to pull out and remove whatever material remains on the ground?
What will the dead moss areas look like in terms of color? It's spread over
a large area (a cluster here, a cluster there) and I detest the thought of
expending much effort.

Thanks so much.
