Is it ok to cut excess roots off of oak trees before planting them?

Yes, it's generally acceptable to trim excess roots from oak trees before planting, especially if the roots are damaged or excessively long. However, be cautious not to remove too many roots, as this can stress the tree and hinder its establishment. Aim to retain a healthy root system to ensure the tree can absorb water and nutrients effectively after transplanting. Always use clean, sharp tools to minimize the risk of infection.
