> Still, the institute’s research has some potentially useful findings. Jackson’s research on seeding milkweed (the host plant for monarch caterpillars) in road ditches with existing vegetation showed abysmal results without applying herbicides, such as Roundup, prior to planting. “You get precisely no plants,” Jackson said. “You use Roundup once, you get a few more, and, if you round it up a couple of times, you get a few more.”<p>Yeah right. People are doing no dig gardening now by simply putting a layer of cardboard over grass or whatever below you want to get rid off, and placing a layer of compost on top and guess what it works fairly well.<p>But sure, we need Roundup for everything so spray it liberally for "nature". And it's "science" based. Horrific.
