OK, I need some help. Our property is in southeast Kansas. I have two problems: 1.) My chain link fence around the 3 acres of my shop has weeds, more weeds, and MORE WEEDS growing in it. Last year we used KillzAll 41%, some fertilizer and surfactant which killed most of the weeds. But, they came back with a vengeance this year!!!! I want to PERMANENTLY kill the weeds! I have been looking at Krovar and other 'soil sterilizers.' Any suggestions? Would I be better off using diesel? 2.) Did I mention we also have a REAL problem with Eastern Red Cedar and Honey Locust trees??? How do I KILLLLLLLL them!!!!!! I sprayed KillzAll on some of the cedars last year. It seems to be having an affect on them now. I have also tried Pronone Power Pellets (75% Hexazinone). I think they thought it was fertilizer! HELP!! Any and all suggestion are greatly appreciated!!!
