Anyone tried Tagetes minuta (Peruvian mint aka Mexican Marigold) to eradicate bindweed?

Read it's roots eliminate bindweed among other perennial weeds and immediately ordered 1500 seeds. It can grow as tall as 6' but would be an annual in my zone.

    Tried it years ago. The bindweed choked it out!

    if it were that easy bindweed would have become extinct by now

    @nutcutlet It did seem like a bit of a miracle cure. Worth trying for a season though.

    Anything that can eliminate bindweed in our garden is probably an even worse problem waiting to happen.   We'll just carry on hoeing and forking as we find it.

    It works on ground elder, but I have found the only thing that works on bindweed is glyphosate.

    Devon.

    It secretes a chemical  something out of the roots that the ground elder doesn't like. (allelopathy)

    It did not work on ground elder either when we tried.
