Buying Information

Getting rid of poison ivy is not an easy task, but it can be done with the right weed killer and some basic knowledge.

Non-Chemical Poison Ivy Control

While it is possible to rid your yard of poison ivy without the use of chemical herbicide, organic methods take copious amounts of time and effort. The most difficult part of eliminating poison ivy is that the whole plant must be destroyed. Without the use of toxic chemicals, you will have to use a lot of elbow grease to pull the plant out of the ground, roots and all. However, even with the most careful weeding, it is still possible to miss some underground parts of the plant. If even the tiniest bit remains, the plant will sprout new growth and need to be pulled again.

Chemical Poison Ivy Control

Chemical herbicides work much faster and with less personal effort. The drawback is that many of these chemicals kill desirable plants as well as poison ivy. Some of them are also toxic to humans, so careful handling is necessary. You will want to wear long sleeves as well as protective gloves and be certain to launder clothing separately from the regular family wash.

Herbicides that contain glyphosate, triclopyr, or a three-way herbicide that contains 2,4-D amine, dicamba, and mecoprop work best on eliminating poison ivy and inhibiting regrowth. The optimal time for application of these pesticides is in late spring and early summer as the poison ivy plants are in their active growth phase.

Be prepared to repeat the application if necessary. Even the most powerful herbicide won’t be able to reach all the roots. Depending on weather and outside temperature, it may take several days or even weeks to see if your removal efforts have been successful. If you see any new growth, respray. Repeated application on new growth will eventually cause this stubborn plant to die back completely.
