I purchased the root waterer to use to water bushes, etc. I don't think I focused at all on the 'soil breaker' part of this. But OH BOY is this awesome for weeding out those long tap rooted weeds that are 10+ years old! We've save a ton of $$ in chiropractic bills! I'm working now on finding a gentle way to use the waterer that will make my tomatoes happy without disturbing the roots. Pretty sure it's possible and now that our dry summer PNW weather has set in, I'm identifying a bunch of applications... hydrangeas, viburnum, dahlias, roses, etc.
