although poison oak grows somewhat differently than poison ivy, my wife and i have successfully cleared several acres of the stuff as follows:

don appropriate PPE (personal protective equipment)

prune back clumps or vines removing most of the above ground parts of plant....

saturate (with sprayer) the pruned stems and any remaining leaves with a double the recommended mixture of "brush be gone" concentrate.

on any sprouts coming back in early spring when leaves are tender, a double strenght mixture of "weed be gone" concentrate finishes off the plants.

good luck mr. miller


GSF are people too!
