Presentation description:
Container-grown trees are a popular stock type among arborists and landscapers; however, trees grown in standard plastic nursery containers often develop malformed root systems, namely circling roots, which can inhibit young tree establishment. Over the years, several techniques have been promoted to remediate circling roots such as teasing, slicing, shaving, and bare-rooting. In this program, we will summarize the results of over decade’s worth of trials conducted by our lab on the effects of root modification techniques on tree survival, growth, physiology, and root quality.
