Have you tried watering it? It may not be the type of tree, but the fact that no one has given the tree any water. Maybe if this trees neighbors were kind enough to give it a drink, it would survive.

Have you looked closely? The soil surrounding these trees is rather moist. Therefore, it's unlikely a water problem since a nearby tree planting, another species, is doing fine. And by the way, it's "tree's neighbors."

Sad to say that the 2 trees I reported on last month have now died; another one (of the same species as the dead 2) is in the process of of dying. :(

Of the 4 trees "replanted," there's only 1 healthy tree which is a different species than the other 3.
Keep in mind that that whoever planted them has wasted at least 4 trees in a little more than 1yr.
For the next re-planting, I'd really suggest and prefer that trees identical to the only healthy & surviving one are used.

UPDATE March, 2012: Oops, I was WRONG. The trees I mentioned above are now sprouting. I guess they naturally shed during the colder months. I assumed they were evergreens, nope. Consider this issue closed and a non-issue at that.
