Hello. Those are wonderful FAQs, since I've been looking into moss I've gotten pretty fascinated with it, so thank you. My question is this: we have a very old (crumbling, but we like it) brick patio, pretty large, and I've been trying to encourage the moss that grows between the bricks, hoping some day to have all moss outlining all bricks.

But of course I have lots of weeds and grass growing up in the cracks, so all summer I patiently -- well, not so patiently toward the end of summer -- pulled out grass and tucked in moss. But I see now this is an endless job and will never look as good as I want it to. So should I just pull out all the grass once and for all, taking a lot of moss with it, and plant new moss, and if so, what kind. Or I guess I could gather moss from around our house and yard (we have lots) and try to plant that in the cracks. Or ...any ideas about how should I proceed? Is there anything that would kill (or preferably, discourage) the grass but not ruin the soil for the moss? I don't want to put any substance at all down because I don't want to kill any moss and also I don't use any chemicals anywhere on the property except some Roundup in the gravel driveway once or twice a summer (and really the weeds don't seem to mind that much:)) Any advice would be welcome. I'd love to plant different kinds of moss on the patio, especially around the edges where there are a few inches of soil from all the years an old euonymous vine hung over the wall. But I would love to hear from the moss experts. Please forgive someone brand new to cultivating moss, if this is not the right question. Thank you!
