Soaker is the best for watering a plant's root ball, plus it's the most water efficient, as you aren't dampening a large area of soil superficially (which is lost to evaporation more quickly without actually watering the plants) but instead soaking a small area deeply to reach the roots. Soaker is my favorite... What are y'all using hoses for..

I just use jet at point-blank and bore my way to the roots. What can be more efficient then spraying the roots directly? /s
