I don't know about the cedars, but I have been actively putting in Christmas each of the last 4 winters - not too many any one year. At about 3 years I am noticing the needles and smallest parts of these trees have decayed away but a decent skeleton still remains. However, when snagged they are pretty soft and break easily now. That may be good for retreiving lures, but I gotta think the trees will only have value for another year or two. Thus the continual replenishing each year. That might seem like a bit of a hassle, but they are free, convienient and readily available each year at exactly the time I like to put them in!
