I'm Bill Elzey with Showplace Lawns. How to get rid of poison ivy and poison oak. I will agree that is some of the nastiest stuff there is. The best thing that I have found to do with that is to spray it with the spray product called Finale. And this particular is a concentrate, breaks down into a usable product by four ounces per gallon of water. Spray the poison ivy, the poison oak with the spray. Spray it really good and heavy. Finale goes to work and usually does its job within about four to five days. You will then need to come back with a really good grubbing hoe and shovel, dig this plant up out of the ground because both of these plants have a very nasty habit of not dying all the way down and coming back. So if you hit it with Finale spray, then come back and dig it up, you'll be in a lot better shape, and that's the only way possible of getting rid of it. Finale is what is called a non-selective herbicide, which means that anything that it touches, it's going to take care of. It will wipe out anything you get it on, so if you're in an application where there's plants you need to keep, be very careful and direct it to just where you want it to go. Finale works good around trees. You do not have to worry so much about destroying the tree root because Finale goes to the root of the plant that you spray it on, does it's job and then disperses and disappears on you so there is no build up or no damage within tree roots. Now, having said that, don't go pour gallons and gallons around there. That might be a different story, but again, spray it really good, being careful to get only what you want sprayed, coming back within a week or so and digging the rest of it up, the only way to get rid of both poison ivy and poison oak.
