RE: Roundup or equivalent
Got a trick for you guys. If you use generic glyphosphates or even Roundup Pro, and you can't kill sedges and bulbous weeds( both Glyphosphate and Roundup cannot kill certain sedges fully because sedge is not a grass, and many forms develop tubers or bulblits that hinder the herbicide), use halosulfuron mixed to the appropriate water needed. If Manage(halosulfuron) doesn't appeal to you, you can buy chemicals like Finale, which is a glufosonate and can replace the use of glyphosphate, of which can effectively kill and manage sedges, broadleaf weeds, grasses and certain shrub-like weeds that Roundup or generic glyphosphate cannot kill effectively. This will not create a toxic medium, since being a topical agent for foliage application, and breaks down very quickly after the plant has died. I can see the weeds die within 1-4 days, where glyphosphate can take up to a week. Just to let you know, there are more effective herbicides on the market, so you don't always have to just buy glyphosphate or the Roundup family.
I am reminded everyday that life is too precious by my best friend, Lt. Ken Ballard, who lost his life while serving in Iraq. He fought for our freedom, to do what we do, and how we do it. Hunt till you drop!
