Review: Nuked the horseherb, left my bermuda alone! - Works great! Nuked the horseherb that was taking over large swafts of my yard without bothering my bermuda one bit!
Review: Works great! Here's my method. - This saved us from being overrun by dandelions! We haven't used herbicides for over a decade because of how toxic most are. We were trying to weed dandelions in our grass by hand. We couldn't keep ahead of their spread! (And it was so much work!) I've been using this product since spring of this year and it's now late summer. I spot spray the dandelions in our lawn and in our periwinkle. I really saturate each dandelion. We are making great progress! Our lawn looks much nicer. I'm using a two gallon pump sprayer. I also bought a hose sprayer that mixes as you spray for our rental house where the yard is FULL of dandelions. (But I haven't tried it yet.) With spot spraying I find I need to go around and check ideally sometime between 12 hrs and 2 days for dandelions that aren't fully dying. I spray those again. Often one spray kills the dandelions, two times almost always does. But there may be some extra hardy ones that need to be sprayed more times depending on how well established they are. I think once we get the dandelions eradicated I'll need to do my method twice a year to maintain a dandelion free yard. I'm hoping I'll only need to spray each one one time at that point since they won't be established. I try to spray when it won't rain for at least a couple days and also pause our sprinklers from the time I start spraying until a couple days after my final spray. Also I go around and grab any flowers left behind after a day or two so they won't re-seed. (Especially the ones that ripened after spraying.) They're easy to grab because the stalks rot after spraying. Also watch the temperature. This spray works best when it's between 60-80 degrees outside and where the temperature will stay in that range for at least a few hours after you spray. The pores on the leaves close at hotter/cooler temps and this product must absorb through the leaves. I feel like the lawnweed brew actually kills dandelions better than the deadweed brew, although the deadweed brew works on a lot more weeds and works really well and really fast. (It kills all plants, though, so you can't use it in your lawn without killing the grass.) Also if you spot spray you will have black spots in your grass for a while after you spray until the grass recovers. After that it'll be healthy and beautiful!
