Not sure on this one, the leaves don't quite look the right shape/size and I was looking for more red on the stem but it is spring..... Anyone able to help me out and confirm if this is poison ivy or not?

Thx

From the shape and number of leaflets, the terminal leaflet having a longer petiole (stalk) and there being a typical flower cluster coming in the middle.

One image?

How about taking pictures from additional angles - especially some that show those pinnate compound (trifoliate) leaves and their attachment to the stem?

If you are willing to pull some of this up (wear gloves), you might be able to take some better pictures of all the plant's parts by laying it down on a sidewalk, driveway, or some such. Get shots of the stems, arrangement of leaf attachment along stems, flowers, etc.

Ok adding a couple more pics. They are shiny because I am not taking chances and spraying them with a vinegar/salt/soap solution. Any other suggestions on removal other than obviously digging them up by roots and trashing them? Thankfully so far it just seems to be around the outskirts of the property, we moved in in October and I didn't get a good scope of what was in the back woods until now, just worried my kids are going to stumble into if it is in fact poison ivy.

There are different species of Poison Ivy and leaves are sometimes variable but it sure looks like Toxicodendron to me! I found this page listing three types found in Ontario (also with photos of "look-alikes"): http://ontariotrees.com/main/g... You can probably rule out T. vernix because it grows like a tree.

The following are from our database:

Western Poison Ivy (Toxicodendron rydbergii)



Poison Ivy (Toxicodendron radicans)

My advice is always to leave it alone. Most people way over-estimate their actual exposure to it.

But if it absolutely must be removed (i.e. it's in the middle of the yard or a small child is rolling around in it), I recommend synthetic brush killer applied several times. It's the surest, fastest, way to make sure it's gone. But then again since it is a native species it's very likely everywhere and this little patch is just the part you most easily see.

Well I am covered in what my wife thought was chicken pox but I think I stumbled into this patch of poison ivy with a weedwhacker and sent it all over me... Not overestimating, trust me. In this case, it must die. It was a sad day for any three leafed plant in my backyard today.

Haha. Just be aware that in a few months or couple years it will likely come back. The seeds are dispersed by birds. In any area where it once grew, it will very likely grow again unless you literally pave everything. It's a really resilient plant.
Keep going!
