Salt can effectively kill tree roots, but timing varies. Small roots might take a few weeks, while larger systems could require several months. Ensure safety by drilling holes into roots and packing with rock salt, avoiding soil contamination. Then, water lightly to help salt penetrate without washing away. Monitor the area, and repeat if needed. Remember, this method can damage surrounding vegetation, so use cautiously. Consider consulting a professional for large or significant trees to avoid unintended damage to your landscape.
