I have a new customer who has a pebble yard (there are alot of these in Florida) anyhow she just purchased the home and paid me to clean up the back yard (Overgrown Grass) and I did such a nice job I talked her into paying me $300 to remove the weeds in the front of her home and re-mulch 2 small islands. I also charged $75 for a gallon of concentrated Round-up. Anyhow my question is Do you think the round-up will do the job? I plan on just using my trimmer to cut down weeds and spray the entire front yard. has anyone been here before? any suggestions to make job easier?
