|I have some Thuja green giant trees and would like them to come in fuller how should I prune them? If I take a clipping from them how do you get them to create new roots for planting?|
|Thuja Green Giant naturally grows in a tall, narrow habit. If you want them to become fuller you can lightly shear them in the spring, just as new growth begins. Only take off a few inches. If you prune back to the bare parts of the branches, no new growth will develop. It's difficult to propagate a cutting from an arborvitae. If you'd like to try, you can follow the detailed instructions in the following extension publication: http://www.ces.ncsu.edu/depts/...
Best wishes with your arborvitaes.
