I'd like to bury the dripline with minimal disturbance to the turf (and minimum labor!) to a depth of no more than a couple of inches. First thought was to pry a slit in the soil with a shovel and simply tuck the line in, then tamp the soil back down. Much easier said than done. Even with considerable prying, the slit is too narrow and closes up before the line is put in. Roots make digging a narrow trench fairly destructive; the kerf is apt to be about as wide as it is deep and hard work to boot.
Does anybody know of a tool for this purpose? I'm aware of vibratory plows, but that seems like overkill if the goal is just a 2" burial depth. Some kind of tool that I can either stand on to press a slot in damp soil or a spreader-like tool similer to an inside out post hole digger might work, but I've never seen such a device and don't know what it would be called. A shovel with a blade about 1/2" thick would be a start.
When it's damp the soil is fairly pliable and there are no rocks, so some kind of soil pusher or piercer has a decent chance of working. Digging in the usual sense promises to be much harder work and there are close to 2000 feet of line to bury. The OD of the dripline is only about 5/8", so the actual volume of soil to be displaced is rather small compared to what is typically moved by digging.
Thanks for reading, and any guidance!
