Encouraging the Moss to Grow
Shade, Shade And More Shade … Then LOTS Of Patience 
Moss grows best in shady locations. Think about where you would find moss in a natural setting – normally in a shady, cool-ish and damp location, right? Like the woods, or by shady areas next to a stream; or under a tree where it is shaded, damp and cool. Blazing hot locations are not the place where we would find moss! So think about this when you are deciding where to set your item to begin the “growing” process.
After you have applied your mixture to the item, place it in your specially chosen nice cool, shaded area. You’ll need to keep an eye on it and mist it often enough to keep it slightly damp. Again, just think about how moss grows in the wild. It is found in damp, shaded spots.
Additional Comments
With any of the above recipes, nothing is so “set in cement” that a slight variance here or there will make much of a difference. This is not rocket science! Mix up the quantity you’ll need following the ratios given a closely as possible.
Let me say it one last time! The important thing is to keep your item in a shady and cool spot and to MIST it regularly. Then, PATIENCE is a must as moss grows very slowly. It may take a few months to over a year for moss to begin growing.
And you know, it’s not just hypertufa or concrete garden containers or clay pots that you can add moss to. There are so many wonderful ways you can utilize this technique. Think about this … you can even encourage moss to grow on stones, rocks, even your garden walls! You can really help Mother Nature along by using this technique if you want lots of mossy areas or items in your garden.
I wish you fun and the best of luck with this ‘how to grow moss’ project.
