Mulch likely to kill it, after which it will turn to humus and help improve the soil. In fact, moss is a soil builder. Where it grows on rocks long enough a substrate develops that other plants are able to root into.

Thank you, bboy, I wasn't sure if it would just grow and also cover the mulch. I'll get spreading!

Starts on compacted surfaces where there is a film of moisture. Fluffy top of fresh mulch not too good.

As far as I know, moss doesn't cause a problem in the garden. Some people just don't like it. Personally, I think it's beautiful, and I let it grow. I even encourage it. I just got back from a neighbor's house where I took a load of lovely emerald moss off their hands.

I love moss too.

Moss not a problem for me, love it, in fact I'm hoping it takes over the whole lawn.

i agree, moss is great. in fact, i love the feel of a lawn that is being over taken by moss. it feels much better on the feet than grass alone.

as an aside, what is the deal with the obsession with perfect lawns? they are water and fertilizer hogs and are a pain to maintain. i have really grown to appriciate the concept of the eco-lawn.

I don't know what the reason for the obsession is. My DH has it bad. I could easily live without a front lawn at all. The lawn is a constant frustration, I keep wanting to enlarge all of the beds by a foot or two, he says no. It is lumpy, weedy, mossy and I'm afraid I'm going to break an ankle on it one of these days it is so uneven, despite ten wheelbarrow loads of sand and compost spread on it last year.
