What do you'll chg. for installing flats, in my case lots and lots of iy. Usually I charge 1.5x plant cost, plus a little more for pick-up/delivery. That is if the plants are not guaranteed....For guaranteed plants the price is 2.5 x..... The problem with flats is that it is soooo time consuming. I was thinking of charging 1.6 or 1.65 x plant cost so I am still motivated to get the work done quick, but make the extra $ for the added time. Any thoughts of suggestions.
