I have a large back yard but it has issues of course, that's my luck... We had a few very large trees that we cut, opened up some sun and space, but the roots are of course still running all through the ground. Elm and Silver Maple. I also have a septic tank smack in the middle of the yard, right at a focal point... I don't know where the drain lines run, but as with my luck I am pretty sure they are under where I HAVE to put the garden. The yard is deep but rather narrow and we have a well/propane tank and a driveway and will be adding an outbuilding, so there just isn't anywhere else to put it where it will have access to a water hose. The soil seems good, but just too packed and hard to use. I cant' till it because of all the roots. So I was thinking of adding raised beds. Can I put raised beds over the leach field of my septic? And how deep should the beds be. I am worried that if they are too shallow the packed soil underneath will prevent drainage? I don't think it is clay-like, just has been driven over a lot and that sort of thing. Any ideas?
