Conversely, some tree species aggressively sprout from the roots even after the tree is cut down and the stump ground up.

How much root damage can a tree survive?

Many plants will survive and recover from root damage if the damage does not exceed 1/4 of the total root zone. Most of the important feeder roots of trees or shrubs are within the upper six inches of the soil. If damaged, the uptake of water and nutrients is restricted reducing growth.

How far do fir tree roots spread?

This can cause liability and safety concerns. Root pruning is more injurious to old mature trees than it is for younger more vigorous trees.
