The most famous thistle patch in MN

[SD51555]

In my experience, thistle and burdock both thrive in compacted, old pasture settings. Have you ever dealt with burdock? Your take on thistles makes good sense to me, and I'm not concerned with them. Burdock is an entirely different matter. Is there a no-till approach you would recommend? The amount of seed in the seed bank makes it feel hopeless.

I’ve got burdock in my yard plot. It’s a low calcium plant. I’ve got the benefit of this being a 1/10th acre plot. I spread 200 lbs (or 1-ton rate) gypsum on this plot in September specifically to try to change the geology to not favor burdock anymore. I have hit that plot with high dose calcium (lime and gypsum) at least twice before. It’s responded well, but the burdock is still around. It’s not advancing, but it’s also not gone yet.

I think this was throw and roll day.

This was a few weeks later.

Maybe a month later. By this point, the gypsum hadn’t received any rain to start it working.

I’m anxious to see this patch green up this year.

Those old Canada thistle bones are thatch now.
