What tree has the strongest root system?

The deepest primary roots, called taproots, emerge as radicles from germinated seeds and continue to grow as the tree matures. White oaks (Quercus alba), hickories (Carya sect. Carya), walnuts (Juglans microcarpanigra) and hornbeam cultivars have strong, deep taproots.

Does cutting tree roots damage tree?

Trenching and digging in the soil near trees can cut roots, and this can damage the tree resulting in tree decline or the tree falling over (See: fallen tree from cutting roots).
