We have a 300-ft. gravel driveway and have occasionally put down fresh gravel and graded it via a sort of big rake contraption that pulls behind a vehicle, weighing it down with cinderblocks. One question I would like opinions on is how to keep potholes from forming and getting deeper... Mostly because I will rake out my plants and ferns along the drive and then my husband will go along and toss all the leaves I raked (those I didn't get in the debris can) back onto the plants because he believes "organic material like leaves will compact into the gravel and make potholes form." Huh? Anyone care to offer thoughts on the introduction of 'foreign materials' into the gravel? Considering we have deciduous trees all along it, this could be a bit hard to do.
