Any plant with 3 leaves I totally leave alone, honey comes and pulls it for me. I sometimes with spray with round up for poison ivy then he will pull the dead plant for me. I have gotten pretty good at spotting it.
Being allergic to flowers totally shocked me. I have never had allergies, have always reacted to poison ivy though. Nothing has ever bothered me, but they say you can start getting them after exposure.
When we were small, my older sister and I rolled down a hill while dad was working on helping build the public pool. Well needless to say, the hill was covered with poison ivy. I had it from the top of my head to my feet, in hair, lips eyes ear, arms legs between fingers toes every bare inch of body exposed. I remember sitting in a bathtub full of oatmeal and being totally miserable. That may have helped start my lifetime reaction to the stuff.
I was grooming plants this weekend, long sleeves, heavy leather gloves, any plant with the small hairs got cut let it drop where it was, picked up with a pitchfork to be loaded into my tractor and dumped down our cliff, a nice dead fall for critters. We nicely have a 10-15 foot cliff right at the edge of our woods (all our land) where I put all the cuttings. They just go away over time, great mulch pile eventually lol.
