How to kill the ivy on my trees and on my wooden fence?

So summer is near and the ivy is everywhere. The previous owners must have planted it as groundcover for our otherwise bare backyard. However, the ivy has crawled its way and create a jungle going up the trunks of our tall trees. It has crawled its way over our wooden fence and into our neighbor's yard.





I don't want to kill all the ivy in the yard because we don't feel like planting grass. Plus I like all the wildlife that inhabits our backyard. However, I want to kill ALL the ivy by and on the fence and on the trees.





How do I go about doing this? I thought that if I simply cut the ivy vines in half on the trees they would do, but they're still green and that was two-three months ago???





Do I need chemicals? If so, what is the most effective thing to use on the ivy? Is this going to be expensive for me to do? Has anyone ever done this, killing ivy on the trees and other structures?

Okay. Here is what u must do. Cut the bottom of the ivy. Take round up. Concentrated and don't dilute it. Pour the roundup in a spray bottle and when u cut the vines spray the bottom where u cut. The absorbtion will kill the ivy. But wait till there is no rain for about 2 days so the ivy is thirsty. Now. After you do this do it again the next day. And this will do the trick. If you don't dilute the roundup. The concentration of it is too much for the ivy. U can do this for under 10 bucks.
Reply:Yes its easy to kill with a poison ivy herbicide available from the garden store. Spray it ONLY on the base of the ivy; as you do not want to get it on other things. If you want, use a spray bottle left over from an after shower product; and do not use the bottle again. Make sure all of the chemicals are out of the shower bottle before adding the herbicide. Label it so children do not get into it. Don't spray when windy or there is a chance of rain or erosion from run-offs.
Reply:Roundup dosen't work that ivy is so resiliant .I would constantly hack it to the ground if you can reach it .I would find someone with there Q.A.L. Qualified applic ators license. They might be able to get there hands on some good stuff.It may be a little more but for the time and re- application it would be worth it. Round up is just a wast of time. If you wanna go green I would hack it off of the trees and keep your eye on it so you dont't have to do any applicating at all. I've heard that diesel fuel will do the trick but thats totally illegal .
Reply:What you need is Roundup. The thing with ivy is that it grows into long runners and from the runners it sends out new roots and they'll dig into anything. Find the place where you want the ivy to stop growing and find the closest root. Cut the plant there and shoot only the root on the part you want to die with the Roundup. If you do that, you won't kill the rest of the plant. Only the part you don't want will die and then you can keep the ivy you want in your yard. I wish you luck with that situation. Ivy is extremely durable and can be hard to control once it gets out out of control.
