What are the best methods for preventing salt damage to granite outdoor tree boxes?

Granite outdoor tree boxes add elegance to landscapes but are vulnerable to salt damage during winter. To protect them, follow these best methods:

1. Seal the Granite: Apply a high-quality penetrating sealer annually to create a barrier against salt absorption.

2. Use Salt Alternatives: Replace rock salt with magnesium chloride or calcium chloride, which are less harmful to granite.

3. Rinse Regularly: Flush the granite with water to remove salt residues before they penetrate the surface.

4. Install Barriers: Place physical barriers like rubber mats or plastic liners between the granite and salt-treated areas.

5. Prompt Cleanup: Remove snow and ice manually to minimize salt usage and exposure.

By implementing these strategies, you can preserve the beauty and longevity of your granite tree boxes even in harsh winter conditions.
