Ok, so I've killed every single spruce I've ever owned. Probably 8 or so. I'm getting them from nurseries, and they are very healthy when I get them. They range from Colorado blue spruce, to bird's nest spruce, Norway spruce, and others. Clearly, I'm doing something wrong with the root systems. Who can advise me on the best way to handle new nursery spruce trees? I love the way spruces look, and I really want to get a handle on them.
