where ever i find the moss i'll note what the conditions are where i found it and i'll do my best to duplicate it. one thing moss does not like it city water chlorine or chloramines kill moss most will grow almost anywhere but hate to be disturbed
I had moss growing back by the shed that I kept removing and throwing out. The moss was in dry shade. Now it is in wet sun. I just took a clump of moss and set it on a wet rock. It just took off. It's been one of the easiest plants that I have grown!
The area behind the waterfall is a sheet of moss. It is gorgeous. I should take a picture of it when the pump is off.
