Unfortunately, once the nimblewill weeds are up and thriving the only way to kill it is to carefully spot treat with a glyphosate product such as Agrisel Gly Pho-Sel Pro. Agrisel Gly Pho-Sel Pro is a non-selective herbicide which means it will kill most types of vegetation including desirable turfgrasses, so care must be used when applying this product to the nimbelwill weeds. Once you’ve killed off nimblewill patches, you can reseed the bare spots a week or so later or patch with sod. Spray at least a few extra inches around your nimblewill patches to take out any runners.
