In the late summer of 2011 we had this company do some landscaping and plantings for us. Three trees were planted and were guaranteed for one year. All three trees died. We had another arbourist look at the trees and he told us that; one was planted too deeply, another had its roots exposed (too high), the holes for the root balls were barely large enough for the root balls and they were still wrapped in burlap. Before the year was up we asked to have the dead trees replaced and were told "no"...all the trees shouldn't die. They would only replace one tree. The worker who came to plant that tree shared with us that he planted 6 trees on his own property, and 5 of them died. The nursery where he bought the trees replaced all 5.
