Hi ya'll I need Help. I cut only 8 yards just to supplement income. I only cut, do not spray pesticides, herbisides, or weed killers. Have not had time to learn about the differant programs. I know that I am missing out on some extra income here. The help I need is on my yard which is on NC/SC border. I need a good fert program. I also have some weeds I need help with some stray onions and also some stuff that looks like chick weed, it has little purple flowers. What would be the best thing to spray on it that will not kill my grass. Thanks in advance.
