well, my almost-free-hay turned out to be a problem..

Are cockleburs same as burdock? Seems like when I was in Kansas we called them cockleburs.
Well, I was too curious to wait for your answer, I looked it up.
Here's a description of both. Mine is bigger than yours - I don't consider that bragging - more complaining!!!

Ok. Burdock has leaves that are very large and the bur is fuzzy-like.

We have both. Cocklebur is 20 times more prolific.

Cocklebur produces 2 seeds in each pod from a much smaller plant, and Burdock produces 20-40 from each pod. Maybe because they flower & produce seed first year? I'm sure either one is invasive.

Cocklebur is 20 times more invasive in our region. I have seen where farmers let it go and it can achieve almost a pure stand of cocklebur. Especially around the barns, feedlots, pens, etc. Burdock is limited to isolated plants randomly dispersed. At least that is the nature of the two plants in this area.
