One of my new customers wants to kill all of the existing dandelions and prevent new ones from coming back. Same goes for all his other broad leaf weeds. I suggested in mid feb. that he needed to aerate and apply a pre m. And he refused. Said that weeds weren't bad in his yard.... LoL. How far from right was he. So now he wants me to apply a weed and feed to take out the dandelions... I am new to the whole idea of fert pre and post m and all. But it is 70 percent rain friday, 60 percent saturday and he would like it to be applied before it rains. Which is fine for a granular weed and feed. But will it work. Thank you, Jonathan P.S. i plan on getting a friend to do it for me who has the proper equip and experience.
