My favorite weapon for digging deep-rooted stuff is my trenching shovel. First I water deeply for several days in a row to soften the soil. Then I attack with my trenching shovel, with a 10" long blade, but since it's only 3" wide, it's much easier to force into soil. You can't believe some of the monsters this 60 year old, 5'3" old lady has defeated that way.
