Yea dawg, you definitely don't glyso large ass areas to kill an area to replant something else. If you wanna do that, you cover it in cardboard an woodchips.
I bring up glyso because I know the importance of ecology. I also know when human beings should be able to use chemicals thoughtfully for their utility in combating pesky invasive weeds, especially in areas that aren't supposed to have plants in them. We shouldn't be afraid to be the masters of our domain. That being said, nothing is more beautiful than the butterflies and the bees. As with most things, it's all in moderation. My 2 sats.
