I have crabgrass growing in the barberry. Can't reach in to pull it, thorns, OUCH!
Yes, Dimension 2EW Herbicide can be sprayed directly on the crabgrass that is growing in and around the pygmy barberry and boxwoods. This product should not be sprayed over the top of these ornamentals. Keep in mind that Dimension is a pre-emergent herbicide and will only control newly emerged crabgrass up to the 4-tiller stage.
