Terry from Salisbury writes

Can I apply Tenacity Herbicide as a post emergent to kill actively growing weeds now and will it work to prevent crabgrass from germinating or do I need to wait until the crabgrass is actively growing in June to treat with Tenacity Herbicide?


If you are applying Tenacity Herbicide for a crabgrass pre-emergent, then you would apply in late early spring before soil temperatures reach about 55 degrees. Keep in mind that if you are not overseeding in the spring, you usually want to use a different pre-emergent with longer soil residual or add another one for longer and more complete weed prevention. We have more information in our Crabgrass Pre-Emergent Guide here.
