A few years ago my grandpa maintained a garden in a corner of our property. (He even made the fence for it out of tree clippings) He's gone now and my father had the bright idea of putting a giant pile of dirt in there a few years back still. It's been 3-4 years since this place has been a proper garden. I really want one this year although I need advice. Do I try and spread the dirt over the entire area? Or do I just make a Mini-Terrace garden? Also if the option is the terrace thing, then, how do I do it?
