This will not stop all the weeds, but the few that make it through can be easily picked by hand.Australian Buttercup Australian Buttercup You can also try to use wood chips to cover a certain area where you do not want anything to grow. This may take more time than using a synthetic herbicide, but you can feel a little better about using these products. You can also try pouring boiling hot water or spraying white vinegar on the target plants. This is probably one of the most difficult methods because there is no assurance that you will get the whole plant out this way. You can manually pull the plants out of the ground. If you don’t plan on using herbicides, there are a few organic methods you can use to try to get rid of toxic plants. If you follow the instructions precisely, then everything should run smoothly for you. Once you have purchased the herbicide you will want to make sure to follow the label posted on the container. You can find many herbicides meant for yard use by simply searching the term online. This can be especially easy if you own a grass lawn and use an herbicide that targets broadleaf (non-grass) species. The easiest but possibly most controversial way to get rid of poisonous plants is by using herbicides. ![]()
