Hi
Hopefully you'll get some good tips.lol locating appropriate mosses has proven difficult as well as the usual problems assosiated with S. florida. Not a moss but "moss like " Selaginellas . Tropical species of course to avoid dormant periods. S. Martinsii, for sure
Sails through most cold spells but does go dormant.
I don't grow them as you suggest but in pots and an outdoor terrarium. have had no luck as a garden plant
for several reasons .
Hope you get some good "Moss suggestions!!! gary

One challenge of trying to garden with moss is that you usually can't buy them. They also tend to be fussy regarding the type of substrate on which they will grow. A moss that you find growing on rotting logs might not like growing on soil or rocks. Some will only grow on the bark of trees. In addition it is hard to find someone knowledgeable enough to help you identify them.

Perhaps the best approach is to locate existing mosses growing on the soil or other substrate on which you want them to grow and use fragments to start new colonies. It also help to eliminate competition, so if there is moss growing in a part of your yard and you want it to spread it could help to remove surrounding vegetation.
