How long will the residual of Weed-Out Lawn herbicide with Trimec keep killing weeds?


Typically this product should kill and prevent weeds for 1 season, about 3 to 4 months.  This product will work much better if you apply a pre-emergent first before weeds start to germinate in the early spring and late fall.
