Answer: There are many different kinds of moss, and the one you use must be adapted to the planting site. Moss is interesting in that it will appear in areas where it is well suited because the spores blow in on the wind. If you can locate some moss growing in a spot similar to where you want to grow moss, you can transplant small patches of it and they will fill in on their own. The idea of mixing moss with buttermilk (live culture) and whirling it in the blender (use an old blender, it is terrible for the blade) simply makes it easier to "paint" the moss over the area where you want it to cover. That means you can cover a larger area with the same amount of "sod".
If it is a moss that typically grows in a damp and shady spot for instance then you must provide it damp shade. If it normally grows on a certain type of rock then you must have that type of rock. If the area is not suitable the moss will not take. Typically you would need a pH below about 6.0 and keep the area misted for dampness for several weeks while the moss establishes. You will also want to net the surface (cover it with netting) each fall to make clean up of fallen leaves easier, or at least rake it free of seasonal debris. You will also need to weed your moss periodically. Enjoy!
