I dislike adding chemicals to my environment so I try to use whatever alternatives I can find that will give me a desired result. I have a proliferation of poison ivy vines and one of the methods I have used to kill those plants is as follows: Vinegar, salt and dish soap Start with a gallon of white vinegar. The “average” vinegar is 5% acidic and will work just fine, but if you can find one that’s 10% or 20% your mixture will be more potent. Pour the vinegar into a pot and heat it over the stove. Add 1 cup of salt and stir until the salt dissolves. Let it cool, then add 2 tablespoons of liquid dish soap. Vinegar, when diluted with a gallon of water makes a good fertilizer for acid-loving plants like azaleas, rhododendrons and blueberries. When mixed full strength with salt, it works very much like Round-Up. The dish soap helps the mixture to stick to the leaves. Pour the mixture into a spray bottle. Set the sprayer to stream (not mist) to for better control. Be careful where you spray because it will damage any leaf that it hits. Be Patient Spraying your plants with a systemic herbicide or the vinegar mixture will not work overnight. After its absorbed into the leaves it takes time before it destroys the root system. Give it 2 weeks, then spray the plant again if necessary. It may take more than one application to do the job. Poison ivy is a tough plant with strong roots.
That works well for me for the poison ivy and oak I have growing around here. I always try to spray when I know it's not going to rain for a few days as that tends to wash the solution off the leaves. Lots of sunshine and heat will combine to shrivel up the biggest leaves on down to the small ones. It seems to work as well as Roundup but without all the negative chemical side effects.
You can compost dead poison ivy, but handle it as if it was still alive, and never burn it. The poison can be carried by smoke.
My dad ended up in the hospital one from breathing the smoke of burning poison ivy. I'm very allergic so I don'd even compost it. I put it in plastic bags and bring it to the dump...errrrr..... recycling center
Goats are pretty much immune to the toxin in poison ivy. I'd love to get a few again. They make great companions as well. I think I'll call my next one NotADog
Notta for short? Make sure it's a billy or it might attract some, ah, disreputable immigrants of the undocumented type.
I had milk goats that would not eat poison ivy. Sniff, snort, shake their head and move on to greener pickings. Possible they had it to soft and could be picky.
Fortunately, due to our strict quarantine laws *glares at Mrs Depp, Boo and Pistol* Australia is not afflicted with Poison Ivy or Poison Oak. Here are some ideas for eradication. P.I.'s pretty resilient, you may have to monitor the "eradicated" area for signs of regrowth, and continue eradication measures until there is no regrowth.
