Generally, the root system will extend at least as far as the canopy of the tree (if unpruned), but some may have a root system up to three times as wide as the canopy, or drip line of the tree. However, with crepe mytle trees, there's no need to worry much about invasive roots, as their root systems are not aggressive, meaning they are not strong enough to pose any major threat to nearby structures or plants. While they do not usually have an extensive root system, it is always recommended that they be planted at least 5-10 feet from foundations, walkways, etc.
