How do I kill poison ivy that is grown up in a bush that I do not want to kill?

First get some good long gloves. Cut the poison ivy to the ground. Rip off your other shrub and put into plastic bags to dispose of. Now kill the root-you can try round up brush killer sprayed onto the cut off part of the vine, however, I find that Green Light cut stump and vine killer is the one product that works well AND in ONE SHOT. No reapplications are needed.

If you just spray or paint the leaves it will take several applications to kill the vines. Poison ivy is really tough to kill using that method

Reynwater is right... and her method sounds a lot better than the roundup injected under ivy bark via hypodermic needle that I was going to suggest. I'm not usually into using roundup but this is the best application for it I can think of. If you just cut the ivy at the root(s) it would just re-sprout.

pass to a plant nursery and %. up a bottle of "TECNU Poison o.ok.N-Ivy air purifier." (I swear by skill of those products.) pass to abode Depot and purchase a hazmat (unsafe components) tournament. it relatively is a quite inexpensive, skinny white tournament which you slip on over your clothing and it will shop you all varieties of discomfort if it prevents you from getting into touch with the poison ivy. placed the tecnu, a bucket of warm soapy water, a hose, and a roll of paper towel exterior. placed on previous clothing, and gloves and then the tournament. in case your arms are uncovered, placed on gloves which you would be able to throw away once you're completed. make confident your face and eyes additionally are coated by skill of something preserving which you additionally can throw away. Now, intently inwind the poison ivy from the Lilac branches. using severe care to not touch your face or any area of your dermis, intently and punctiliously eliminate the roots of the poison ivy. It comes up exceptionally person-friendly. place each of the plant and roots in a rubbish bag, and then place that rubbish bag into yet another rubbish bag. Take great pains to not get any of the Urushiol (poison ivy toxin) on the 2d bag. Now eliminate the hazmet tournament and placed it in yet another rubbish bag. finally eliminate the gloves and the different piece of preserving clothing that got here into touch with the Urushiol. Use the tecnu to bathe your arms. do not use water. in basic terms rub the technu into your arms and the different dermis that could have been uncovered, then dab the tecnu off your dermis with a paper towel. placed the paper towel into the rubbish bag with the hazmet tournament. Repeat with the tecnu various cases. Then wash your arms in the warmth soapy water and rinse with the hose. with any success, you will possibly are growing to be to be rid of the poison ivy, you will not have broken the lillac, and you will not have contaminated any of your dermis with the undesirable rash.

paint brush, undiluted (UN diluted) roundup, paint on "Ivan's" leaves. (oh, Ivan is poison ivy, you know not to get roundup on your desirable plant. You knew that.)
