Theyre wrapped in burlap, 4' wide balls on them. Whats the easiest way or machine to use to dig holes large enough for these? I cant get even a garden tractor back there or bobcat or anything. whats the next best thing? I have a customer, that already bought 8 trees, he currently has some cheap 4' tall evergreens in the back yard, im removing 8 and installing 8 much larger trees NOT in the same hole, thus needing to dig probably by hand 8 large holes. What should i charge JUST for labor ? The soil probably isnt digging friendly, lot of NJ junk clay/small rock soil.
