How much would you charge in labor per plant to install 9,000 3 gallon shrubs in one mass planting in one large area. Plants to be all grouped together a few feet apart. How many plants can be installed per man hour? On a slope, so no dingo auger. The tricky part is figuring man hours for plant mobilization. What kind of auger would you recommend? Is there a super light one man auger? I have a stihl 2 cycle Auger but i think its max capacity is a 1 gallon?
