Ok here it is from the grower's perspective. You already admitted that your trees likely died from drought. Yes that sucks, but why would you expect the grower of the trees to replace them in that instance? That isn't the nursery's fault. With that said places like Stark Brother's are playing the odds with the 1 year guarantee. People like Stark Brothers are charging 2-3 times what the tree is worth when you purchase it, that way WHEN it dies they already have the replacement cost built in. Besides the fact that a certain number of people will not request a tree when theirs dies. More money in Stark Brothers pocket. We basically guarantee our trees to leaf out. Beyond that it was either environmental or owners lack of taking care of the tree that caused its death. Which happens a lot (like in the OPs initial comment), why should the nursery be responsible for that? We occasionally make exceptions, we can generally tell when someone is BSing us. I had a guy claim that 80 of his 90 trees died. Went on a rant on how upset he was and that he would never buy trees from us again. I was more than happy to work with him to resolve the issue. When I asked for more information and pictures he went silent. Found out through another source that his wife left them outside his storage building in the sun for a week (he was called away for work) in the bags they were delivered in. He proceeded to try an order more trees the following year.
