To control root spread, consider using root barriers, which are physical barriers installed into the soil to prevent roots from growing into unwanted areas. Regularly prune the roots by creating a trench around the plant and cutting any encroaching roots. Planting in containers or raised beds can also help manage root spread, and choose tree and shrub species known for having less invasive root systems.
