I have an oppurtunity to bid on a job mulching around the trees for a HOA. There are a few hundred trees. I have done plenty of mulching in my time but i am wondering how do i figure out how much mulch i need? Can someone who has experience doing this plese give me some help? Trees have not been done in a few years. All trees will need to have an edge dug around them and grass pulled away from trees. Then Mulched. I am thinking 2 guys 20 minutes per tree to Edge, weed and mulch. Does this sound about right? Also, they want a seperate price on mulch and labor. Was told if i was to high on the mulch that they would get the mulch and i would supply the labor. If they supplied the mulch, my labor price would need to go up. My reason for thinking this is because instead of working from a truck, i now have to go and load their mulch from a set location every time i need mulch. Am i thinking right?
