Answer: Spruces are shallow rooted trees and I suspect the dry conditions were the problem, although without seeing the trees and their planting conditions it is really impossible to diagnose. (For instance, spruce will not tolerate soggy soil, either.) You might wish to consult with the nursery where you purchased the trees and/or with a professional arborist or with your County Extension (579-0985) to try to establish the cause of the problem before you replant. I'm so sorry about your trees.
