I’m contemplating installing an in ground mini-bog in a sloped part of my garden which will allow for good drainage (using a pipe across to where it becomes above ground) and good water control. My plan is to use a peat/silica-sand/perlite mix. Am I right in thinking I can go several years between changing out the soil, or is something that needs to be done annually?
