I yank out deep-rooted plants from Bull Mallow to Bull Thistle to Palo Verde seedlings with my Root Jack. But it helps to remember a few things. First, you need to kind of bang the Root Jack into the stem at a bit of an angle, to make the sides open and grasp it. A bit of a trick. automatic once learned. You may need to hold skinny shoots steady and wiggle the jack onto them. (Still the only sane way to deal with some deep tap-rooted plants!) Some stems are slippery. It may take a few tries to get down to a layer that the Root Jack teeth can grasp. While it's good to have softer soil, some plants are better left dry so the teeth can grip better.
Also, don't forget to take a look at the bottom of the handle once in a while, and oil the hinge parts occasionally so the teeth will open easily. I wish I'd painted my handle pink so I'd have remembered to pick my Root Jack up after I answered the phone and lost it for months. A can of spray paint is a lot cheaper than a new handle. Just the same, ol' RJ has lasted for years and years despite my mistreatment, though I shudder to think of my fate should the handle break before my new one is delivered!
