Poison ivy #786017

Asked April 06, 2022, 3:19 PM EDT

I am a new homeowner in the area and my backyard is very shaded and has a creek running though it. There is a lot of poison ivy and I want to eradicate it with environmentally friendly methods if possible, but we are open to chemical treatment if natural methods are ineffective or unrealistic. Do you have any staff that can provide guidance or a site visit to help us formulate a plan?

Thank you for your question

Dear Homeowner,

There are a couple of approaches to dealing with poison ivy. You can use a mechanical approach: hand-pulling. Depending on the amount you would need to pull, the terrain, and whether you have other plants nearby that you want to keep, this may be the most environmentally-friendly option.

"Hand-pulling can be used when the plants are in moist or loose soils where the plants can be easily pulled out. Usually the roots can be pulled out in long pieces. Remove as much of the roots as possible when pulling plants because sections of the root left in the ground can re-sprout. Of course the downside to hand-pulling poison ivy is taking a chance on skin contact and getting a rash. When hand-pulling poison ivy, avoid skin contact by wearing gloves, pants, shoes, and maybe even long sleeves could help. After working around poison ivy remember to wash as soon as possible with soap and cool water. Also remember to wash clothes and gloves immediately afterwards to remove the oil left by poison ivy."

If that approach is not sufficient, chemical measures may need to be employed.

"There are several herbicides that can be used to help in controlling poison ivy. Herbicides like glyphosate (Roundup) and triclopyr (Brush-B-Gon Poison Ivy Killer) can be used for poison ivy control. One application of an herbicide will not eliminate it but can be effective over time. The herbicides are more effective in the early summer when there are new shoots and actively growing foliage. Do be aware that these herbicides can harm other plants in your landscape. Carefully spot spray to avoid contact with plants you want to keep and avoid spraying on windy days to prevent drift."

Finally, there is another fun and eco-friendly option: goats!

Thank you for your speedy response! 

Being highly allergic to poison ivy, we have been reluctant to employ the dig method. We have been pouring boiling water on the sprouts that have just started to emerge. There are not massive areas of poison ivy, but sprouts here and there. This has been highly effective in killing the tops. Do you know for what duration this must be done and at what frequency in order for the roots to finally give up and die?

Eliza,I cannot find information on how long the hot water method will be effective. But to improve the chances of total eradication you could also use solarization. This involves smothering the plants and using the sun to burn any remaining roots. Place black plastic or heavy cardboard on top of the area, extending as far beyond it as you can to catch any shoots that may escape. Leave this on for a year. I hope this works as I know how painful poison ivy can be.
