I transplanted this maple from my neighbors yard about 2 years ago. It was originally planted very poorly: compacted subsoil, hole just big enough for the root ball, didn't take the burlap off, and covered the surface with landscape fabric right up to the trunk. I didn't think it had much of a chance to survive. Something damaged the bark around the trunk severely, and it has this white stuff that might be a fungal disease? There are some dead branches that I'm leaving in to deter the deer from eating leaves in those areas. There were also plenty of bad pruning cuts that still need to be cleaned up. Overall, this has been a great success. I made sure the root zone got some good quality compost, and also gave it a few doses of compost extract to get the life going in the soil. I put another layer of compost on top as mulch, and the seeds it contained made a nice cover crop.
