our neighbors just got 4 austrian pines transplanted onto there lawn. the trees are 6"-8" in caliper. the company that moved them did NOT overdig the holes that the treespade made. there is no mulch on them, they are not staked and they have not been watered. is overdiging necessary when using a treespade?? the soil is Black dirt for the first 8-10" and its sand and clay mix after that. were located in southeast michigan. do these trees have a chance at surviving ??? i give them 1 month before there dead. any opnions would be appreciated.
