### Key Considerations:

**Soil Types**: The type of soil (e.g., clay, loam, sand) affects root depth. Clay soils may require less depth compared to sandy soils that drain faster.**Frost Line**: In colder climates, tree planting or root mitigation should consider the frost line (the depth at which the soil freezes) to avoid root damage.**Climate**: Warmer states like Florida and Hawaii do not have significant frost lines, allowing for shallower planting depths.
