All trees include a one (1) year warranty. All trees which die or are not 75% alive with the central leader 100% alive, as determined by the Purchaser, within one (1) year after planting must be  replaced the same or the following planting season. Trees determined to be unsatisfactory by the Purchaser will be required to be removed and replaced by the Bidder with the same size tree and species originally planted unless change is authorized by the Purchaser within thirty (3) days of written notification by the Purchaser.  There shall be no additional charges for the necessary replacement trees. The Bidder shall not be required to replace trees damaged by vehicle accidents or acts of vandalism. All replacement trees will carry a one (1) year warranty extension as if the replacement tree was the original planted tree, from the date that the actual replanting is complete.  The same guideline outlined above will be used to determine the tree’s condition for replacement.
