Moss covered rocks lend a sense of age and earthiness to your garden. This is a guide about growing moss on rocks.
Tips for growing moss on rocks.
I've never actually tried this, but I've been meaning to. Here is a recipe I've been told works well to give planters and rocks that aged look.
Put a handful of whatever type of moss you want to grow into a blender with 1/2 teaspoon of sugar and a can of cheap beer (or buttermilk) and mix it up just long enough for it to get thick and soupy. For the sake of your blender, try and remove as much dirt from the moss as you can.
Use a paint brush to spread the mixture over items you want to grow moss on, including on the ground between stones in walkways and paths. Keep these items in the shade and mist them once in a while to keep then from drying out. In anywhere from a few months to a year you should start seeing some moss growth.
I've also read you can paint plain yogurt directly onto planters and rocks and then rub those items with garden dirt containing moss spores. If you're not familiar with what moss spores look like, when they sprout up from the moss, they look like little bristles of hair with wheat seeds on the tips.

The only problem I had was the rocks that got more sun, the moss would dry out and die. But if I kept it damp with the hose now and then it would survive. Not sure what makes it work unless it is the cultures in the buttermilk, but it worked for me. I hope it works for you.

How do you go about growing moss using buttermilk or yogurt? I need moss for bonsai.
I heard that you just paint plain yogurt on rocks with a paintbrush. I tried this one time and discovered that my big sweet dog had followed behind me happily licking it all off so I don't know if it works! I'm curious to see other feedback.
We have a waterfall in our back yard that we have been trying to get moss to grow on for years. Finally it is doing really well. (Good ole buttermilk/yogurt)The birds love to take baths in this waterfall, as it has a couple of places that "fit" them just right. Personal bath tubs if you will, LOL

After starting moss on rocks with the buttermilk recipe can you cover with clear plastic?

I've never heard of doing that, but it seems like a good idea- Like creating a little mini-greenhouse while it gets started. The only thing I would worry about is fermentation... I wouldn't wrap them tightly, but leave a way for air to circulate while still reatining the greenhouse effect. Otherwise, the whole project might rot. Ew.
