I love this stuff. BurnOut is a great and accurate name, but they should call it Disintegrator! Here in our Eastern NC transition zone, we have lots of pesky weeds and grasses. Getting Fescue to outcompete the many competing grass species is hard enough. But like sore losers, all the pesky grasses that lose in the yard, set up shop in my beds. Crabgrass, Bermuda, and the highly prolific Japanese stiltgrass. It used to be an endless struggle to keep beds clear for even a week in the height of growing season. Now I do this: let the grass/weeds grow to maybe 4-6 inches everywhere where they take. Around here that doesn't take long. Then I take my push mower and walk it right through the beds and chop everything down. Then I immediately spray what I just cut with BurnOut. And the result is amazing. It doesn't just kill the weeds. It doesn't just burn out the weeds. It freaking DISINTEGRATES THEM. Usually within 48 hours. And by disintegrate, I mean they are dead, gone for the rest of the season, and there is not even a trace that they ever existed. It literally burns them to dust and they blow away in the wind. This used to make me nervous given that my beds are also full of azaelas and boxwoods. I feared that getting this on them would have the same result. But I was pleasantly surprised to find that it doesn't. You can pretty much spray it 'over the top' of many ornamentals, though I would always prove that to yourself before going all in. Also as others have noted, this DOES give year over year cumulative results. I have one large bed that would be covered end to end with Japanese Stiltgrass by mid may. As of today 5/13, only one small patch is just coming in. I just ordered more burnout, so within 4 days (including the 2 that i will spend waiting for delivery) that stiltgrass will be DUST. And likely won't come back next year at all. And for the record this stuff has never clogged any of my sprayers (I need an arsenal of them around here). I absolutely LOVE this stuff though it could stand to be just a little cheaper.One more tip I'll share. First and foremost, ALWAYS use products like these exactly as directed, when directed and where directed. If you don't you're probably just going to waste your money. Once you've done that and gotten an accurate picture of what proper use looks like, then maybe you can cheat a little to stretch your dollar. Here's one such cheat I found: If you have one of those Ortho or Spectracide 1 quart hose sprayer bottles, they are great for this. Empty and clean it (or don't, more weed killer is better right). Then fill it with pure BurnOut concentrate. You should be able to treat a pretty big area this way. BurnOut says this would treat 1500 s/f but I can typically treat 2000-2500 s/f pretty effectively this way. Not sure if Bonide would back me on this, but I've proven it to myself more than once. For the price, and the size of my beds, it helps to be able to stretch it a little this way. The picture above is of one of my beds one week after treatment. This bed had been completely covered with knee high Japanese Stiltgrass. Note that it is effectively disintegrated. And hasn't returned in 2 years BTW. I treated this bed using the Ortho sprayer and the procedure described in the first paragraph. Couldn't have asked for better results.
