What are the best methods for preventing rodent burrowing in stone outdoor tree boxes?

Rodents can cause significant damage by burrowing in stone outdoor tree boxes, compromising plant health and garden aesthetics. Here are the best methods to prevent this issue:

1. Install Hardware Cloth: Line the bottom and sides of the tree box with a sturdy hardware cloth (1/4-inch mesh) to block rodents from digging.

2. Use Gravel or Rocks: Fill the base of the box with gravel or small rocks, creating an inhospitable environment for burrowing.

3. Apply Natural Repellents: Sprinkle cayenne pepper, peppermint oil, or commercial rodent repellents around the box to deter pests.

4. Maintain Cleanliness: Remove fallen fruits, seeds, and debris near the tree box to eliminate food sources attracting rodents.

5. Regular Inspections: Check for signs of burrowing and repair any gaps or cracks in the stone structure promptly.

By implementing these strategies, you can protect your stone tree boxes from rodent damage and maintain a thriving outdoor space.
