Have a client that has a few patches of dirt with what used to have a lot of weeds in it. She cleared out most of the weeds but not all of them. Thing is there were and still are lots and lots of stickers in the ground. One step in and your shoe is covered. The hard kind that resemble a game of jacks. Not good identifying stickers yet, Sorry. Well, she does not want to pay for sod so we are going to re-seed. How can I seed this area? Is there a method for removing the stickers first? I don't think solarizing will kill them. If I just seed will the grass surface first or will the stickers germinate and cover the area first? Any help please??
