chop it down, spray it with weed killer, strip its bark, uproot it and leave it in the sun to wither and die. why do you want to kill an olive tree though. olives are delicious and oh-so-good for you.

Perhaps you are talking about Russian Olive trees. They are on the noxious weed list in several states including Wyoming. A 4" diameter tree will use 150 gallons of water per day. In dry States where Russian Olive trees line the irrigation ditches, it is a major problem. Cut it down! Spray the stump with a specialty herbicide such as tordon or picloram. Check with your local County extension agent to find recommended herbicides. Pile and burn the slash, (The seeds will not be destroyed by the fire). haul the ashes to a landfill.
