eastern red cedar or juniperus virginiana has a considerably less compact habit than some of the other junipers commonly used in bonsai. they are strong plants but they tend to get cedar apple rust which, as far as i can tell, will usually not kill the tree. i dont have much experience with junipers so its a lot of trial and error usually. i had one die over the winter and i'm not exactly sure what caused its death. they seem to be hardy to very low temperatures. i speculate that i may have over-worked the roots, which is why i'm leaving this one in a larger pot and no root work has been done since it was collected in spring 2010. i really like this one so i'm trying to take it slower. i feed it alternately with organic and chemical fertilizer. it has responded well to pruning and pinching. i have read that its difficult to train one in a cascade because of being so apically dominant but this one is developing fine so far and the cascading branch is showing no signs of weakness.
