Jane from Albany, Ny writes
Crabgrass has taken over front lawn. Applied Tenacity in early August and crabgrass white/brown and dying 2 1/2 - 3 weeks later. Now I want to do a fall overseed. Do the massive areas of dead crabgrass (and some nutsedge) all have to be pulled up before roughing up, spreading top soil and reseeding? Need to reseed soon, but the crabgrass won't have withered and died in time. (in Mid-state NY).
When using Tenacity Herbicide you should remove the thatch layer before reseeding, and it is best to aerate prior to the application as well. You want to be sure that the new seed has the best chance to come in contact with the soil.
