Advice needed
 

Setting up my pond right now.....the basics of it now to be finished next
spring, I'll be having a rock stepping stone pathway to the pond from my
patio and I want moss grown in between stones. What is the best type moss
to use and the best time to plant?? My pond will have a small top pond
acting as a veggie filter....what is the best plant for that? (no fish in
top pond)

Thanks in advance.....
