Hello. I would appreciate some assistance. I live on Long Island, in zone 7.
I have a brick walkway and brick patio, both in full sun. Moss has been
growing between the bricks. My wife and I rather like the look. Whenever
grass or weeds begin to take between the bricks, I use Roundup, as I don't
want them growing there for the way it looks, and so that their growth and
roots don't upset the lay of the bricks. I understand that moss doesn't have
true roots like other plants. Will the moss growth eventually push the
bricks aside, or don't I have anything to worry about in that regard for
some time? I suppose that if it eventually gets bad I can use Roundup at a
later date to kill or control it.

Moss seems to do rather well in our yard, in both full and part shade.
Again, we rather like the look. Is the abundance of moss growth indicative
though of any soil, moisture, or any other problem we should be aware of?
Thanks in advance for any advice you can offer.
