I have a bulb auger I've used, but I mostly use
the tubular d.h. punch doo-dad or the little
trowel for any dirt holes since the soil is sandy
and it's just a couple of seconds to punch a hole.
A drill and battery and auger is also heavier to
tote. Now, making holes in the black dirt at some
areas around here is easier with the drill and
auger. Just depends on where you're standing
