Quick and effect way to kill roots without damaging the ground surrounding them

[James]

What is a Quick way to kill weeds and other things. down on st. croix we consider it a weed but its still a tree. its called tan tan or thats the only name i know for it. it sprouts fast spreds fast and is thick as hell. unless you take out the WHOLE root it comes back stronger and thicker. i have tried burning, pickaxes, and pulling with cars, even a friend of mine tried a frag grenade( denated in the ground and burried close to the tan tan) share your worst roots and weeds and effective way to kill them here.

Spike 20P usually works well on trees or woody stemmed type of plants. Always check the label for application rate information.
