Certified Arborist Practice Test

Question: 1 / 400

What percentage of a tree's root system can be removed when digging a tree for transplanting?

50%

90%

When transplanting a tree, it is generally recommended to remove no more than 30% of its root system. Removing a percentage larger than this can significantly stress the tree and impact its ability to survive and establish after being moved.

Transplanting involves careful consideration of the balance between the above-ground and below-ground portions of the tree. The roots play a crucial role in water and nutrient uptake as well as anchoring the tree in place. A root system that is too small in relation to the tree's size may not provide enough support and resources for the tree to thrive in its new location.

Thus, while transplanting procedures can vary depending on the species and size of the tree, the standard practice emphasizes the importance of minimizing root loss to ensure a greater chance of survival and successful establishment in a new environment.
