I want to ask how often folks repot but since there is no way of knowing how close to the surface there peat was when it was in the wild. I guess it makes more sense to ask What do you look for? How do you know you need to replace the media?
It is one thing to repot potted plants once the peat is to broken down/decayed but replacing the peat in a bog is another.
I have a small bog and would like to make a large one but if I will need to replace the media every year or two I have second thoughts.
Any and all insights appreciated
