I am new to the fetilizer and pesticide application aspect of this business and I need a little help on application pricing. I am using Momentum herbicide and lesco fertilizer, so my material cost is about 16.50 per bag of fertilizer and 140.00 for 2.5 gallons of herbicide. Now I just need to know how much to charge for application and mark-up on chemicals. Keep in mind I am located in a rural area in southern ohio, so I can't charge the big city rates. thanks!
