I know we're past the time where we put the Halts down. I had been planning on just fertilizing since my lawn is pretty much weed free. But I was at Target tonight and saw that they had several bags on clearance. Since I can get the stuff with Halts for about the same price as regular fertilizer. I was thinking about putting it down instead in mid June. It would prevent any new broadleaf and grassy weeds from germinating in July/August, No?
