Maintenance
It is reported to be susceptible to a pest called Loopers that can strip the leaves from a plant. This may be more of a problem in hotter, drier areas or plants that are in full sun or otherwise stressed. It is said to be resistant to oak root fungus.. Because it spreads by rhizomes, remove any unwanted suckers to contain width. To maintain an upright form, prune wandering side branches in the dry season to avoid infection. This plant tolerates shearing and can be trained into a semi-formal hedge.
