Answer 1

Rooting Habit of Liquidambar styraciflua L., sweetgum

Early root development varies with site conditions. On well-drained bottom-land sites a deep taproot with numerous well-developed laterals usually develops rapidly.

On wet sites with poor drainage, however, the root system is shallow and wide spreading, with little tendency shown for taproot development.

On gravelly ridges, hillsides, and upland piedmont sites, sweetgum develops a particularly strong taproot, with a range up to 10 m, so it is very resistant to wind.
