When/If To Remove Knotweed After Glyphosate?
Have some Japanese knotweed in my orchard area. I foliar sprayed it and also used a syringe to inject 41% glyphosate. I know I will have to repeat this in the fall (and likely for years to come). I also know how easily it roots even from tiny chunks. Should I remove the above ground portions at some point? I know it can take up to two weeks for glyphosate to completely kill the plant (at least, the parts I sprayed). Do I wait that long to pull anything I see? I also know I need to very carefully dispose of anything I remove (I’ll burn it).
