Need help on what to charge on fertilizer application. I've got about 1.5 acres to fertilize. There are some weeds but mostly like a wild onion type weed to get rid of. Goal is to have a lush green lawn. I don't do much fertilizer applications so I need help on what you all suggest as far as what to put down and how much to charge. It's fairly hilly and will be pushing with push spreader unless I can rent a rider.
