I have a minimal amount of plot experience. I have 10.5 acres we're building a house on and lots of it in cedars bordering a creek and crops. There is approx 1/8th acre section that is cleared I'm wanting to plant on. I've mowed, let it grow back somewhat, and now sprayed with 50% glyphosate. I mixed at about 2oz per gallon. This kills on contact so shouldn't harm soil and future planting right? I'm hoping to burn after it dies and will harrow and plant. I've used arrest at the farm on clover plots but never a roundup type killer. I'm hoping to plant soon as it's been wet and I'd like to have some growth by late sept early oct.
