Jun 05, This tree, Abies koreana, can grow to over 30 feet. You will not be able to trim it back severely. Abies can be sheared very lightly, cutting only into the current season's new growth.

But when I did some fact finding on google, found that it could grow much bigger, 10'' in years according to number of nursery web sites. I like the form and look of the tree, so would like to know if it can be kept small over the years by pruning or some other means.
