Mowing poison ivy is a mixed bag:

It is good to mow it since that will keep it in check. Without leaves it can't survive, so it won't invade your lawn.

Poison ivy loves roadsides. It loves the sunlight. Birds drop the seeds there, often while sitting on power lines overhead.

We often see poison ivy growing over guard rails, but this example was particularly spectactular.

I once got one of the strangest phone calls of my life, and it was because of this website.

A fellow explained that he had a question about poison ivy and my answer might determine if he spent the rest of his life in prison.

A viewer sent in this photo of a poison ivy (or possibly poison oak) vine.

What is striking about this image is how the leaves of three come off the main stem clearly alternating left and right. You rarely get such a clear view of how this works since the leaves usually hide the stems.
