I had used a lot of cardboard in my beds........... it won't stop sedge.
@kidfishing what is Snap Shot? And do you happen to know the name of the other sedge killers? The guy that I was talking with actually thinks I have "False Sedge" instead of true nutsedge because he says normally nutsedge prefers damp soils. Mine if very sandy and definitely not damp so he is pretty sure it is false sedge, although I just took a picture for him the other day to send to him for him to look at the "bloom" on it and verify that. I just haven't gotten it to him.
The gentleman that I am dealing with works for a company called Crop Production Services - and they sell large volumes to farmers, timber companies, and even the company that I work for. Where I work, they have to use specialty weed killers because we are close to the river so it has to be something that won't harm the fish or contaminate the water supply. You might do some googling and see if there are any specialty chemical suppliers near you. But they can also sell small quantities - like my 2.5 gals of arsenal. Way more than I needed, but I will eventually use it for other things. I haven't priced any sedgehammer since I never located it...... I need to get back with him to check his prices and to let him see that picture.
I live in a rural area with open fields that have BAD weed problems and my yard is full of all types of weeds and various grasses as well. I have Bermuda, Johnson grass now, lots of sedge, lots of sandburs, and bahai grass, plus tons of other things that I can't even identify......I pulled weeds recently that were close to 6' tall because I have been gone most of the summer and I had a few areas that really got away from me.
I have this dream of having a nice "lawn" without weeds and sedge but I think if I killed all that out I might have bare soil!
I am not sure that I will ever be able to afford to get rid of all the weeds and grasses that I don't want....................
