How to get rid of a huge patch of poison ivy?

I have found that dishsoap by itself rarely does anything. It helps glue the other products to the weeds. https://www.hgtv.com/outdoors/flowers-and-plants/how-to-kill-poison-ivy

Rubber gloves long sleeves and long pants plus enclosed shoes and pull it out by the hands you have to get the roots of the ivy out.

round-up yard strength isn't enough; there are specific sprays for Poison Ivy/woody plants that is the same chemical, but in much stronger concentration; it will take repeated sprayings, as well as keeping an eye out for reseeded or runners that have spread. Contact you local garden supply center --

Use mix of vinegar, dawn detergent and

3 cups white vinegar

1/2 cup table salt

1 tablespoon liquid detergent or soap (I use Dawn) for stick-to-itiveness.

Directions

1. Mix vinegar and salt until the salt is completely dissolved. Stir in liquid dish soap, and pour into a spray bottle.
2. Spray onto the green growing leaves of the plants.
3. Wait a week, then repeat on any survivors. Best time to apply: during a dry spell.

Repeat as necessary.

Here's a post that might help - https://chascrazycreations.com/home-made-weed-killers/

You could try Bonide, that will kill it. You might want to contact your local cooperative county extension to see what they recommend. They have master gardeners to help.

Hello, hope this helps you. Work in sections instead of trying to take out the entire bunch all at once, smaller sections will help you insure you have killed it all. Fill a garden sprayer with undiluted white vinegar. Spray the poison ivy leaves and crown. Avoid overspray on the surrounding soil. Repeat every few days until poison ivy dieback occurs, same goes true for the poison Oak

Hello Lus: Wear protective clothing and maybe even safety glasses. You can use a product called Ground Clear by Ortho. However, it will kill everything it touches, so put it in a spray bottle, or buy the spray, (the refill is cheaper, $5.97 for 24 oz vs $6.97 for a gallon Search Results for ground clear at The Home Depot) and spray the leaves, top and bottom. Put a tarp on the ground to catch any overflow. Also, and this is what I did, was to cut the plant down to about 6" from the ground, putting the cuttings into a bag. Then, I got a syringe filled with the ground clear and injected the remaining stem in several places, and the top. The plant will take the poison to the roots, killing the plant. You may have to do this a couple of times, but it works.

Pay a Gardener to do the Job. Cheaper in the long run!
