Eradicating Invasive Mahonia (Leatherleaf Mahonia)

Cut, Pull, and Treat Stumps

Wear leather gloves and a heavy jacket. Lop each stem at the base, pull the shrub out, and immediately spray the fresh stump with a glyphosate product (Roundup, KillzAll, KleenUp). Birds spread seeds from berries; if neighbors let fruit mature, seedlings will keep appearing.
