Can we trim back Buckthorn trees now?

QUESTION:

Our church planted several Fine Line Buckthorn trees behind a bench in a prayer garden. The trees have been in place for three years and have done very well. There is now concern that the trees are getting to tall and should be shortened. Members want the trees to maintain their natural shapes but come down about 12 inches. Any suggestions on how to trim the trees and when would be the best time to trim the trees? Thank you, Nancy

ANSWER:

​If necessary, buckthorns can be pruned just before new growth begins, which means late winter/early spring. During the summer they can be sheared once or twice to maintain the shape if they are grown as a hedge. A mature FIne Line Buckthorn 's height is normally 5' to 7'.
